Yesterday, I bought an old Lenco C-3000, Panelmaster, spot welder.

Does anyone have one of these or info. on it or even a book/circuit diagram?
Is it a good machine?

I need copper tips- where?

It is supposed to be 2400 amps. for some fraction of a second.

ANY help or info would really be appreciated.

Thanks

Thank you, Mr. Idiot.

I was really asking for folk's opinions here in this newsgroup. I figure
any damn fool would have the wit to check Google, as well. Even me.

However, I do appreciate your links and the time you invested. I really
thought that some of the guys on here would have some tidbit of information
about this model and a source for the tips.

I suspect their opinion was that you should wait more than a couple hours
before whining that nobody was sitting around waiting for the chance to
answer a question for you.

Yep. Any doggoned fool would.

I suspect if you had waited more than a couples hours and given folks a
chance to read your post... Most of the guys who really know their stuff in
here have day jobs, and spent a lot of years working to learn what they
know. I bet a lot of them of only even check the group once a day, and some
only every couple days.

> j/b

P.S. Technically is Mr An Idiot. As in, I. R. An Idiot. Didn't want to
come right out and bust your chops over the name thing since its not obvious
to some folks, and you did call me Mister first.

Mr. Idiot: I try to call even a S.O.B."Mr S.O.B." as that monicker tends to
make the real S.O.B.s feel better about themselves since they seem to need
it.

I always get a grin from folks who state the obvious as if they think their
idea only occured to them and no one else.

This group has an inordinate percentage of extremely knowledgeable folks and
I speculated that many would know of this spot welder. If I expected a
reply that didn't fit with your particular timetable regarding the
appropriate time to wait for a reply before asking again, I really
apologize. Perhaps, deep-breathing exercises and Yoga would be of great
benefit to you. Masturbation, even. If that is still possible for you.

Again, thanks.

Sigh, I can only assume that it is in a fit of pique that after having it
pointed out to you, you still fail to use my name correctly. Oh, well.

That would be... "try google" or "give folks a chance to even see your post
before whining that nobody responded?" Also, based on that last statement I
bet you grin madly every time you speak.

> This group has an inordinate percentage of extremely knowledgeable folks

Well, yes I said that. What was that about stating the obvious?

Apologize? For what. You are impatient. It doesn't hurt me a bit, so why
apologize.

> Perhaps, deep-breathing exercises and Yoga would be of great benefit to

That's just not funny man. I'm an asthmatic, arthritic double amputee. If
I could take deep breaths, do bending exercises or whack off I certainly
would.

I have not seen any traffic on spot welders in this group. I have a
little Miller portable spot welder and have not heard of Lenco before this.

Good Luck,

Thanks, BobH.

Lenco is a huge company that has been around since dirt.
I think they merged with Profax.

I did find a place that can order them for me.

I have never used a spot-welder before and wanted to pick some brains.

Take care.

I can't claim to be a master with it, but I use my mine occasionally. I
have never had any training on one, but I may be able to answer basic
questions. Miller has a booklet on spot welding that has some useful
information on the basics:

Hey, BobH!

Thanks for those links. I didn't have any particular questions other than
wanting hints and do's/don'ts/technique.

What amperange is your machine? This one is supposed to be 2400 amps.

What do you normally spot weld?

Hi j/b,
The current varies depending on the length of the tongs. I have the 12"
tongs so it looks like 5800 Amps (I have the LMSW-
52). I use mine for steel sheetmetal, usually 16 - 22 guage. I do a fair
amount of sheetmetal fabrication for hobby stuff and the spotwelder lets
me build pretty professional looking stuff. Mostly I am building
enclosures for electronics. I have used similar spotwelders on autobody
sheetmetal in the distant past. I bought this one used off Craigs List,
I kind of wish it was the smaller machine because it is easy to blow
holes in the work with this one.

A good mechanical fitup, clean metal and not too much pressure on the
tongs gives decent results with the shortest pulse I can get with the
mechanical switch. Clean tips are also important. Too much tong pressure
or dirty tongs result in blowing a hole in the work. The smaller
machines I have used are easier since they actually take 1 or 2 seconds
to reach welding temperature (Orange to yellow hot on the surface).

I want to try spotwelding stainless, but have not gotten to that yet.

Good Luck,
BobH

Stainless steel spotwelds fine but it really likes to spit at you so
wear safety glasses.

One of my favorite clever ideas with my Miller spotwelder was how to
stud weld with it.
Buy an extra set of tips.
Cut one down so it is about 3/8" across the flat.
Take the other an drill through the middle with a 3/16" bit.
Take some short fillister head 8-32 screws and grind the head so it is
half as thick.
You want fillister head because they have a larger diameter head, but
you can also use round-head screws.
Drop the screw into the hole in the lower tip and place a piece of
sheet metal over it.
Apply spot welding current and presto you have a perfect little welded
stud.
Nice for making small light fixtures and anywhere where you don't want
visible fasteners.

Hey, BobH,

Thanks for the interesting reply. The beast that I have does not have
tongs. It has an ordinary ground clamp and an electrode holder with a 3/8"
copper slug-type tip that is to be pressed against the top sheet and then,
the pushbutton fires a monster contactor (vacuum?) and sparks fly for x
mlliseconds. What fun!


Maybe we could trade?

I should have explained that the electrode is an ordinary but very heavy
gauge cable with the attendent handle, tip and pushbutton.
