And with flux core? Solid welds,but after grinding flat,there's pinholes. Tried brazing over it and grinding back down,50%sucess. Motorcycle parts that show.
Hey mate, seems there's three of us here. I know your comment is a year old, but currently doing the frame of my Honda XR400. Gasless mig, flux core welding, same situation here. How did you fix the pinhole situation? Can't find a good answer anywhere.
@@codymcgrath6191 on a frame, or anything heavier than sheet metal, the problem goes away. Set it just hot enough to get a good puddle. I made 1/4" thick plates to mount my rear master cylinder on my Triumph, no problems. On the sheet metal i was spotting the seam one weld at a time, which was the problem. Getting feed/heat balanced was tricky, and overlap each spot weld by 1/2 diameter of spot. I still want gas, its cleaner and forgiving. I made the oil tank for the bike from 18ga. Steel.

Exact same situation here
