So today I started a new plate and I did the following changes. first went from 125 to 115 on the root pass I focuses on one side of the plate and backing strip and did a foward back motion no circles like last times. So it went way better slag was easy to remove . Uploaded with ImageShack.us Uploaded with ImageShack.us

Reply:I think you are referring to "arc blow". Sometimes if you turn the plate around it will solve the problem. or if you move the ground to the other side of the plate. If you do a lot of grinding on the plate it can magnetize the steel and cause arc blow.CERTIFICATIONS:7018M- H.V.O10718M- H.V.O11018M- H.V.O9N10- H.V.O71T-1-HYM- H.O.V100S1 PULSE ARC 0,035- H.O.V100S1 PULSE ARC 0.045- H.O.VER70S-3 PULSE ARC 0.035 H.O.VER70S-3 PULSE ARC 0.045 H.O.VER5554- H.O.V
Reply:I dont know if its a bad habbit to get into or not, but when I start seeing signs of arc blow I tend to tweak the travel angle down or up , whichever I think will solve it and then jamb it int here and knock that fingernail off the rod |
