120v MIG weld on a 3/8" thick (bevel 60deg)

I actually tried to step away, but just a short word. Be careful about assuming it will shut down before damage is done. Might be wise to still try to limit your full amp welding to 10-20% duty cycle regardless of machine shut down; to prevent damage to the welder.

good advise, A machine will usually start acting funny before it shuts down. Pushing it past that point is only asking for trouble and possible damage to the welding machine. Not to mention the fact that any weld make during the spitting and sputtering before shutdown will be of poor quality.

I've had two stick welders now that had problems. A 110v CF 70 amp that the thermal overload stopped working and the insulation on the base of the leads melted. I now have a 220v 20 amp HF 130 amp stick that cooked the on-off switch with no warning; running max amps (funny thing is the arrow indicator was significantly past the max 130 amp line; so which is wrong? Max amps or indicator arrow?) With 1/8" 6011.

Both I repaired; but they also where both transformer welders; CF was AC only; HF is 130 amp AC/115 amps DC. Newer, inverters; hunting down the cooked micro chip might be way harder then cutting off a burnt wire and re terminating.

Glad to see some guys welding test plates (on-topic). Be safe you fellas don't let those rattle out under the tailgate on the highway and kill somebody!

You guys keep it down I'm going dirtbikin'. With no seatbelt. Before I get too old.

But, please wear a helmet! Already enough brain dead folks in the Welding forum!!

Fifelaker;

Would welding a 3/8" plate with a higher amperage machine (set to 3/8" setting) give similar results to welding with a 110V MIG maxed out?

If not why not? I think I know the answer but just trying to understand.

Thanks

All right folks. Third strike for pruning and the thread has struck out. Next batter.
