I tried my 7kW generator just to see how it behaved, and it does good on TIG, decent on MIG, but Stick welding can bring it to it's knees with the huge in-rush when I first strike the arc and the hot-start kicks it up a notch. 125A with a 35% hot-start will eat up the whole 7 kW for 2 seconds upon arc strike. Then it settles down to about 60% of total power available when the amperage drops down to 125A.
