i have had my welder for about 4 months now and im using it quite a bit but still get the spatter around my welds. i also tried the anti-spatter spray and it helps but something is off. is it my wire speed? the surfaces are ground down to bare metal and clean. what else can cause this? i have welded with gas at at a friends shop and it wasnt as bad but he adjusted everything as far as wire speed, arc volts ect. what am i doing wrong?
