Mig 4f Tee joint on 1/4" thick steel using .035" er70s6 Quick settings welderskills

Scroll down for exact settings used

With overhead short circuit mig welding, there is a tendency for folks to use cold settings for fear that the weld will sag.

I have found that by using a short stick out also know as "contact tip to work distance" (ctwd), simply lowering the wire speed by about 10% works fine for overhead welds.

WELD PROCESS = GMAW, SHORT CIRCUIT MIG, GAS METAL ARC, BARE WIRE MIG

METAL TYPE = CARBON STEEL, COLD ROLLED STEEL, AISI 1010

THICKNESS = 1/4” .250” 6mm

WELD TYPE = Fillet

JOINT TYPE =Tee

POSITION = 4F overhead

VOLTS = 20 volts

WIRE SPEED = 300 IPM

WIRE SIZE = .035"

POLARITY = DCEP

GAS FLOW = 25 CFH C25 GAS or higher depending on nozzle diameter

CTWD = 3/8”-1/2"

FILLER METAL = ER70S6

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 serves of cursive e’s that keeps arc on the leading edge of the puddle

Overhead short circuit mig seems to go better when a short stick out aka contact tip to work distance is maintained along with settings that are almost as hot as a 2f fillet
