Hello.
I'm fixing a small rust hole in a 1995 pickup .
I'm getting holes through the metal, and being a beginner, I can't figure out why.
I'm not sure if the wire speed is too slow or too fast.
The "heat" (amps?) I can't lower any more as the machine is on its lowest setting.
I'm uploading a photo and below are the specs of what I'm working with.
Any advice?
Oddly enough, the first tack welds went beautifully.
Yet after that, I just melt the thin body panel and "eat a hole".
Machine: Lincoln Electric 140 HD
Gas: C25 set at 36 scfh (18 L/min)
Wire: 0.25" (0.6 mm) mild steel
wire speed at 5-1/2 (not sure how this translates to someting measureable)
voltage at 'A' (lowest setting)
