Been having trouble getting the Power Ultra 205P to cut when operating on 120V. Here are the symptoms:

The machine cycles back and forth between the pilot and cutting arc unless the air pressure is reduced to very low levels, about 45 psi. When its this low, the cut is terrible and it splatters all over.

The air is clean and the ground connection is solid.

Oh, and it does have points and they have been adjusted correctly.

I am going to pick up some 0.6mm, 20 amp tips, to see if this will help.

Does anyone have any other ideas to try?

TIA,

Ken
