Re: Project: Tow-Rat (Lil' Blue)
Kinda tought to tell from the pic but it looks like your welds are possibly undercutting a bit. You could try less current which can help the edges of the puddle not melt the base metal around the puddle as much so that area doesnt drain into the puddle and leave a void where it came from. Also, check the arc length or try a shorter arc length to control the heat around the puddle better. do you use some sort of a V or a C pattern with the electrode as you move the puddle around?
