I don't so much mind fixing dents...

[68l30]

The trick to those little buzz box migs is to use the right mix of shielding gas and wire.....I like to run a 95/5 mix.Stay away from those tri mixs and the cooler running blends..If your still tring to weld with the flux core set up .......Your better off with coat hangers and torches.. Be sure to check your power supply. If you have a weak circut your in for a rough time as well.In doing field work, I've found those machines run like a whole new animal when coupled to a generator... Hope it helps.
