I'm using a miller stick welder with 7018 rods. I can't run anywhere close to the amperage most guys say to run without getting severe undercut. My Grandpa had a buddy who was a certified welder, but sadly he passed away a few years ago. He could run 150 amps on drive shaft tubing, but I can't go over 80 amps. On 3/8 inch steel I have to run about 110 amps. Any help would be much appreciated.
