vertical help

admin

So I'm having some issues with vertical.  Basically fillet welds on 3/8 plate.  Now here's the thing.  I can crank my welder up to around 450-500 ipm when i'm vertical welding plate on the bench (nice and clean), but when I try to run high settings when I actually do my verts (flat bed bodies on trucks) I have to crank my welder WAY down.  The only settings I can get it to weld at are 17.4 volts at 260ipm.  The metal on the trucks is not as clean as when I'm bench welding since I have to burn off undercoating and then try and jam a wire wheel up there and get it as clean as I can.  Seems when I start cranking up my welder on trucks the weld will either be extremely concave, or i'll have a terribly unstable puddle thats dripping all over the place.  When I weld at 260ipm runs great, the welds look good, not cold, but I feel like 260ipm is just way to cold for 3/8plate.

Reply:My guess is you are altering some variable. My 1st thought would be increased stickout, but usually running a long stick out gives you a colder weld and you have to turn the machine up, not down..No government ever voluntarily reduces itself in size.
