Generator to power MIG welder

If you plug the welder directly into the generator a 20 amp 120 volt outlet will run a SP100 for light welding. Steve

My SP-100 works fine on a Honda 2500 watt genny

AMPS X VOLTS = WATTS. Add a 30% safety margin and you should be able to run its duty cycle.

A 2600 watt generator would not be adequate for full duty cycle in my opinion, but a 3500 should handle it all day long.

I'm not sure about the sp100t, but some inverters (MIG power supplies) can be sensitive to voltage spikes, sags, etc. I had to replace a varistor on my PowCon after it was loaned for some generator-powered field work.

The little Lincoln SP MIG boxes aren't inverters.

The welder itself is limited to 10% or 15% duty cycle at max output.

Correct.
