Additional on Hobart 140A-120v

[chas]

I met a Native American grad named Matt, of the local Job Corps welding
program. He was also a Boilermakers apprentice. He was good. Damn good. In
fact while enrolled in the Job Corps a welding instructor in another Jobs
Corps site 120 miles away became sick and this Matt student was sent there
for 5 weeks to sub while the instructor recovered.
. . . I had two 3/8" x 6" x 12" that I wished to make into a foot square
plate. He said I'll do it for you. He took my Hobart 120v 140 amp (with
gas) and connected the two in one pass. He took alot of time preparing the
gap (no Vee) and I believe he used about 1/8" gap and had the wire
positioned down to 1/8" from the bottom to start...one pass. Damn, as a
retired journeyman Ironworker, now I not only have to be jealous of the
Pipefitters but the Boilermakers too.

that's some "narrow-groove welding"!

I've done something kind-of similar in steel fabrication - on similar
thickness - catch the wire on the underside edge to start the arc in
the "root" - but keep the arc running along there and multi-layer the
full-thickness "narrow groove" weld. For welds to no particular
specification and with no great strength requirement...

Any recommended practice for this?
