    Hi Todd, Are you REALLY going to weld 1-3/8 solid into 1- 3/4 pipe. Depending on how much solid you are using as to how many Amps you will need. I think you will need to be close to max and you may also need to pre-heat the alloy before welding. I would use an E3 electrode or a "layzir". to get the heat capabilities. 3/32 filler may disappear on you pretty fast at that heat as well. You may be better with 1/8 filler, 4043 or 4943. You will need about 16 cfh of gas.
