MIG Settings for 3F and 4F Tees

Settings for uphill 3f tee 1/4" thickness

19.5 VOLTS 280 IPM .035”
WELD PROCESS = GMAW, SHORT CIRCUIT MIG, GAS METAL ARC, BARE WIRE MIG

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

THICKNESS = 1/4"

WELD TYPE = Fillet weld

JOINT TYPE = TEE JOINT

POSITION = 3f vertical uphill

VOLTS = 19.5 volts

WIRE SPEED = 280 IPM

WIRE SIZE = .035"

POLARITY = DCEP

GAS FLOW = 20-25 CFH C25 GAS

CTWD  = 3/8”-1/2"

FILLER METAL = ER70S6 .035"

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 motionsThis technique traces the front leading edge of the puddle and helps ensure penetration.

Settings for Overhead 4F tee 1/4" thickness

4f tee fillet mig 035 WS END.mov
