Checking welding current

I'm picking up the radiator for the SA 200 Monday, and will be painting and
reassembling according to the wind speed over the next couple of weeks.
When I get the old gal running, I'd like to do a check on the output through
the leads.

Would I do this with a helper and an amp clamp? Set it up to weld, and then
weld with a helper watching an amp clamp on the lead? Is there another type
of tester I should use just on the main lugs off the machine? I'm just
trying to see if the output is good, and is within the range of the controls
indicate. I will be using 50' leads of #1 cable on each leg. I will be
using 7018 1/8" rod in the flat position, and making a dime size pool, and
trying to burn thirty seconds per setting. Stinger positive.

Does this sound like a plausible idea? Other suggestions, caveats, tips,
procedures or whatever appreciated.

Thanks.

Steve

Put a volt meter across the leads, see what it says. Have your helper
read it while welding.

Frankly..I consider the dials on most welders to be only a a way to
figure out what the needle was pointing at the last time it worked
good. Then I use a grease pencil to make a mark for the size/type of
rod it worked well at.

Now there is "shunt ammeters" but I dont have a clue how to hook one
up for your rig.

Just wire wheel some of your scrap, grab a mixture of rod, and burn
it. Set it at what the dial says..then adjust up or down as needed for
each rod.

My Fluke does DC amps. Has a "Max" mode too, where it remembers the max
current - you wouldn't need a helper to read the meter while you're welding.

You could use an automotive starting/charging current meter, which is
a simple DC magnetic meter with grooves on the back for the wire. They
aren't very accurate but you just place it on the lead. The one I have
reads charging current to 75A with 5A graduations, or 400A starting
current to 25A.

6013 or 7014 rod (and maybe 7018, haven't tried it) will weld by
itself if laid flat on the work, then you could let go and read the
meter.

I'd be more concerned with maximum AC line current.

I found a rather nice hall effect AC/DC clamp probe by TPI at FRy's for
about $60 (plug into any DMM), and it's rated for 1,600A AC / 2,000A DC.
A whole lot cheaper than the Fluke equivalent and seems to work just
fine.

You could use a shunt type meter. The most common meter standard for
these are 50 millivolts. You will need a meter movement and a shunt
covering the maximum current you will be reading. The shunt should be
placed in series with either welder lead observing the polarity from the
welder, shunt and meter movement. This will be the most accurate, but a
clamp on attachment to a DVM, as others have suggested, should be quite
adequate.

I would use a DC shunt, as you said, and a regular multimeter set at
the lowest voltage scale (2000 mV in my case).

These shunts are not very expensive.

If you know the gauge and exact length of your cables, you can short
your welder through those cables and measure voltage drop, and arrive
at a fairly good current number based on resistance of cable of your
gauge.

This is really good advise. I would get an analog voltmeter and measure the
voltage drop just across the work lead. Measure the length, look up the
resistance of that size cable and calculate the current. Note the temp of
the cable and correct for that for more accuracy.

Easy, cheap, and accurate.

Your 50 feet of #1 copper lead would have a resistance of about .0063
ohms, so it will display a drop of 6.3 millivolts per amp.

Use a voltmeter on a low-volts scale to measure the voltage from end
to end of the 50 ft cable while welding. Amps will be
volts / .0063 or volts * 159.

So is car starter current.

If it welds OK with the largest appropriate rod, it's working
properly.

That's a good idea. Voltage drop may be about 1 v olt, easily
measurable with good accuracy. There are ohms per foot tables for
various gauges. Attaching one

Yep. Bright yellow case unit. They have a couple models that look
superficially the same, two are AC only and the third is AC/DC and has
the extra DC zero knob on it. It also apparently was rated something
like 800A, but subsequently upgraded with stickers on the package to the
1,600A AC / 2,000A DC rating.

Cheap, for sure. Not as easy as an ammeter. Not very much accurate,
I'd say. You have unknown accuracy in the wire guage, unknown
resistance in the cable connections and in the clamps. Analog meters
are hard to read precisely and are only accurate to a couple of percent.

And a couple of percent isn't accurate enough for a stick welder?

How about the digital clamp on ammeter working with the high RF environment
of an arc?

Who said the measurement would be made beyond the connectors? You?

Four place resistance figures for the cable aren't accurate enough? Its
easy to see an analog meter and integrate out all the variations with an
unstable DC arc. Seems you have never tried to measure the current of a DC
welder.

Stop picking nits.

You need to measure from lug to lug. A couple of percent accuracy is
more than appropriate.

You could make one for well under 10 bux. You'd need to calibrate it.
Might not be quite as accurate as a commercial instrument, though most
DC amp clamps aren't all that accurate either. Ya don't usually need
to know welding current to 1%. 5% or even 10% is probably often
close enough.

Some minor metalworking required, and you'd need to stick 3 or 4
electronic parts together.

The clamp ring could easily be tailored to have a max range of 200
amps, 500 amps or 1000 amps just by changing the width of an air gap.

Linear Hall sensors are available for $1.26 from Digi-Key.
http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=620-1020-ND
A Hall sensor produces a voltage proportional to a magnetic field,
which in turn is proportional to current flowing thru a wire that is
encircled with an iron or steel structure. The steel structure might
be an openable (hinged) ring maybe 1" ID and 2" OD (or whatever) with
an air gap. The hall sensor goes in the air gap, perhaps surrounded
with aluminum, brass, plastic or epoxy so the air gap is the same
every time. Turns out the permeability of the iron or steel really
doesn't matter much at all, and since you're interested in DC it
wouldn't need to be laminations. Solid mild (soft) steel or iron
should work fine.

The elex parts might be the little Hall sensor, a 5-volt regulator
as LM78L05 (about 40 cents), a small cap and a 9-volt battery. You'd
measure the output voltage with an ordinary DVM.

On the other hand, time is money and 60 bux ain't much of it.

The ExTech MA220 400A AC/DC digital clamp meter is spec'd with
accuracy of +/- 3.5% + 6 digits in the region between 300 and 400
amps, +/- 2.5% + 6 digits from 0 to 300 amps.

What the other's said about measuring with a voltmeter and a longer
cable. Just clamp one voltmeter probe onto either the stinger or ground
clamp, the other voltmeter probe onto the other end of the same cable.
You can extend the voltmeter probes using any wire that is handy. The
voltmeter draws negligible current so the voltage drop in the probe
wires is negligible.

You should check the current at several points in the scale. Be prepared
for some funny readings. It's unlikely that the actual current is as
nicely behaved as the settings on the panel would suggest.

You could use a high current shunt kind - they are real time so you have to
watch... cut the lead, make two lugs to the ends and use the lugs to attach
to the ammeter. When not using that - one could get a conduit box or the like
and have the two wires coming on either end and the lugs bolted together and
taped...

Good (there are inexpensive ones that are good enough) clamp meters now use
Hall effect devices to measure DC. Many AC ones do as well.

Auto parts stores have an inexpensive DC ammeter you just hold over the

Yeah they work, but they are not very accurate - that's why they are
cheap, they are only accurate enough for the intended job. Within 25
amps either way is plenty close enough to find a bad starter...

If you want something halfway accurate and repeatable (and perhaps
even with traceable metrology calibration) you'll need either a
Hall-effect clamp-amp that reads DC Current (or an accessory clamp
with a good multimeter), or an inline shunt and meter movement set.

I'm actually not as concerned about the exact number output as much as I
want to know if this old machine will still weld what I want to burn long
enough to pay for itself, and get me going without having to fork over twice
as much for a new one.

Since I'm getting replies all over the map on this one, I have decided to do
the following:

Get some of the rods of diameters I'm going to be welding with. 7018, 6010
and 6011, 1/8" and 3/32". Set the settings at the suggested amperage.
Weld, and see how they run. Then intentionally crank the settings up or
down from the accepted parameters, and see how they act.

I got back home today after a few days in Gomorrah taking care of some
things. I'll go pick up the radiator tomorrow, and if this wind will stop
for a few days, I'll get old Sally painted. In the meantime, there's power
washing at the car wash, WetOrDry sanding, and getting some new medium grade
bolts to put all the shrouding back on. (They had put it all back on with
soft Home Depot grade bolts.) Maybe make the tumbler for the gas tank out
of the barbecue spit turner I have .......... something to burn up a few
days of doodling.

Put it up on blocks and maybe go get some new tires. Get a new tongue where
the lock for the ball works. Torch off the old one. Look for some fenders
locally, although Northern Tools have some I like that have skirts in the
back that would bolt on better. Locate some decent lights. Send off for an
official Lincoln decal package.

I'm having some fun getting this old bucket running again. Pictures will be
available when I'm done. I'm into it about $800 right now.

Steve, if the amperage dial is calibrated properly, you should have a
great time welding 1/8" 7018 at 125 amp setting, especially horizontal.

If that is the case, I would say, to hell with shunts and ammeters.

Bottom line is how she runs regardless of what meters might indicate.
You need no book nor meter to know when a welder is running right or
not.

Hold your phone calls, folks. We have a winner!

I used to get applicants for welding jobs. I'd take them to the shop, turn
the dials on the machines, give them some metal, and tell them how I wanted
it welded. Most came back saying how there was something wrong with the
machine. Some came back with the metal welded up. You could put the
symbols in Fijiian, and a real weldor would figure it out.

This is a very reasonable plan and something you will need to do anyway to
learn the capabilities and character of your individual machine. I think
you are cutting yourself short thought, as these machines are also very good
with 5/32" xx10 & xx18 and will run 3/16 well (but with the rain hat
straight up and obviously using lots of power (& gas)). Testing should
really be done over the full range of output but especially at the higher
and lower end.

I suggest that you will find that most heavy work can be done faster and
with much less distortion by using bigger rods whenever suitable. These
bigger rods are often available (free) after questionable exposures to air &
moisture, see the earlier thread subject 'drying E7018'. Bigger rods also
tend to lay down smoother better appearing beads, (especially horizontal
fillets) and usually it is easier to remove the flux and are less likely to
suffer from flux or rust inclusions when welding dirty or rusty steel.

I quite like to use very small (1/16 or 5/64) 6013 for very light work. I
suggest you buy a small box and sub-package the rods using heavy sealable
plastic freezer bags as even a small box has more rods than you will use for
a long time.

I suggest you will find this is a sweet and very versitile machine with lots
of range.

Good quality bolts (and lock waskers, as you discovered) are cheap
innsurance. They are also much less likely to strip the threads out of
older parts, I suggest you also check the heads of the other bolts such as
the water pump or manifolds to see if they have been replaced with soft
ungraded hardware store bolts.

This and the right color of (good quality) grey paint will make Sally look

I still think you have found a great value, and a machine that should last
you a long time and allow you to do some good work. IMHO you should NEVER
(EVER) use it for thawing pipes.

Good luck.

I was a steel erection contractor for nine years. The main thing I learned
was " stick with the gravy jobs."

I could make more by going out and repairing a gate than I could by building
it from scratch. And only have a couple of hours and one trip in it. I do
not want to get into this as a full time job, but rather a sideline where I
can work when I want and don't have to feed the overhead monster that is
created when a business is started. My wife and I were talking about it
yesterday (she was a CPA), and besides putting the dba under the umbrella of
one of our LLCs, we will probably only get handyman licenses, worker's comp
and liability insurance.

I can't lift a lot any more. I was an Offshore Petroleum Institute
certified rigger, crane operator, able bodied seaman, crane operator, and
had OSHA sponsored courses in rigging all along the way. Still, one has to
rig all that stuff up, and move it around. And usually it's harder when
others present haven't got a clue and either watch you bust butt, or just
watch, or worse yet, try to help. I want to stick to smaller stuff that I
can fix in place, or bring to my home shop and buzz up on the wirefeed. The
low work higher hourly rate jobs.

As it goes, I'm sure I'll make adjustments as I don't like to pass on jobs
that are good money even though I may have to go buy some bigger rods or
some of this and that. I do like the round threaded containers with the
gaskets that one can put a few pounds of rods in, and keep them dry, and not
carry the whole 50#. We do get a bit more rain here than I am used to in my
other location, so will have to protect accordingly. A new toolbox,
probably diamond plate aluminum, is on the horizon. Then I'll make hose
hangers and other goodies to keep my stuff straight on the trailer, and make
locking straps to keep the riffraff from bothering it.

Well, time to go to the big city and pick up the radiator, sandpaper, decal
pack, and fasteners. Not sure how it is where you are, but spring has
sprung here, but we are still having occasional cool windy days, and today
is one of those. A good day for parts chasing.

Film at eleven.

It can often be good to hire on as an employee (or part time contract
employee), get your employer to pay for all consumables, licences,
Worker'sComp and PLPD and do the paperwork AND THE ACTS-REC and you may also
get other H&W and unemployment benefits. You can then rent out your rig for
you to use on the same job as a sideline rental business. This is
especially good if the job is union. I do not know what the tradesman
shortage is like where you are but qualified people who can and will work
are in very short supply in my area and the rates charged by rental shops
for a welder, torch and tools is quite sufficient to give a good profit.
One of the side benefits is that you always come home with a full tank of
gas and usually much other stuff. AFAIK, You can still claim your expenses
as deductions from total income as long as you (not your LLC) do the
renting, YMMV. Your background may result in a foreman or leadhand position
and you may be able to rent your rig as more of a perk and you may not even
need to do much with it.

Where I work, the tradesman shortage means that trained older people are
normally given a younger helper (or two or more) to do ALL the grunt work
lifting and grinding. We have paid our dues working hard and now it is a
case of finding the 'lazy' guy (me) and putting him in charge as he will
find the 'easy' and MUCH more importantly SAFE way to get the job done.
Where I run cranes, the basic qualification is grey hair. Employers will no
longer tolerate unsafe operations and the days of expecting accidents and
injuries is long gone.

The great wages paid by the big jobs have sucked the pool of trained labor
dry and even the local small customers and companies have learned they need
to pay top wages to attract trained people and that their apprentices only
stay until they get qualifications to let them go to bigger money jobs.
This has created opportunities at the local level. Don't sell yourself
short, you are not looking for callbacks, get the maximum return from EVERY
job. IMHO, Do not expect customer loyalty.

Big rods (and gasoline and especially OA are expensive and you can go though
them in a hurry on a big job. Many people have abandoned the flat hourly
rate inluding consumables pricing model and now price as hourly labor +
daily equipment rental + ALL CONSUMABLES EXTRA. It makes your base rate
look very competative but prevents the situation where you only get called
for the high consumable cost jobs.

CAUTION, It is tough to secure a trailer against theft as they are quick and
easy to just lift onto a truck with a small picker and welding equipement is
easy to fence no questions asked.

A good clean rig is the best advertising you can have. The tools a
tradesman uses tell a LOT about the kind of job he will do.

Good luck, YMMV
