Re: 1984 Chevy Custom Deluxe
well as for the pin hole problem, that is a common occurance with flux core welding, try turning up the heat and wire speed just a little on the welder (not sure about the settings on a Harbor Freight welder cause I use a Miller)
and the gun should be held no more than 1/2 to 3/4" away from your work (commonly)
