I'm relatively new to MIG. I've dabbled in the past but never really did much, at least that mattered. I'm making some locking mechanisms to upgrade on cash machines at a bunch of car washes for my part time gig.
I need to weld 3/16 plate to the face of the machine (1/8")
The machine I have is HH140. Settings for this weld were 4/50, 98Ar/2 O2 set at 20 CFH. The weld supply shop did not have tri-mix in a small enough bottle, so that gas is what they recommended.
I don't imagine I'll be doing a lot of stainless in the future, but I'd like to make it work.
Edit: I watched the puddle closely. The 3/16 on top looked like it got a full penetration into the side, but I'm not sure about the 1/8 it' sitting on.
Oh yeah, material unknown, but nonmagnetic, wire is 0.030 Hobart 308L
