MIG WELDING CARBON STEEL UPHILL 1/4" THICK OUTSIDE CORNER

Mig welding uphill with c25 gas requires lower settings that shown on a mig settings chart. Especially on an outside corner joint.

Downhill is easy. But you risk lack of fusion on anything thicker than 1/8".

So it pays to be able to mig weld uphill.

FILLER METAL = ER70S6

ADDITIONAL SETTINGS = 

TIPS:A relatively short stickout aka contact to work distance CTWD of 3/8” to 1/2" makes a big difference.

The technique shown is simple series of upside down V motion.This technique sweeps the arc across the front leading edge of the puddle and helps ensure penetration.
