I was very proud of the way this weld looked. There are so many challenges to overcome on a hotpass. The key for me was to find a amperage I liked that could fuse and move quick with to not suck the root back. Coming out of this welding coupon, I learned that 3/32 filler wire is the way to go with a hot pass. It fuses in the walls of the pipe rapidly and it’s easy to move that little of metal quickly without sucking that root back. There and gone. TWS Proud
