Any insight is better than no insight. I was able to get the
AWS SWPS B2.1-5A-222:1999 for chromium molybdenum steel usinEr90-1..
SPECIFICATIONS STATE "ROOT SHIELDING GAS IS OPTIONAL" BUT WHEN I PRACTICE ON AN OPEN ROOT PRACTICE PLATE ALL I GET AN OXIDIZED ROOT IN THE BACK WITH A DASH OF SUGAR. IS IT EVEN POSIBLE TO WELD AN OPEN ROOT ON PLATE SUCCESSFULLY?
