Gas shielded flux core wires from different companies require slightly different settings even when the same diameter is used.
the settings listed below should help get you very close
WELD PROCESS = DUAL SHIELD FLUX CORE, FCAW-G ( GAS SHIELDED)
METAL TYPE = CARBON STEEL
THICKNESS = 3/8”
WELD TYPE = GROOVE WELD COVER PASS
JOINT TYPE = BUTT JOINT 22.5 BEVELS, 1/4” GAP, 1/4” BACKING BAR
POSITION = 4G OVERHEAD
VOLTS = 25 volts
WIRE SPEED = 360 IPM
WIRE SIZE = .045” LINCOLN ULTRACORE 71A85
POLARITY = DCEP
GAS FLOW = 25-30 CFH C25 GAS
CTWD (STICKOUT) = 3/4”-1 “
FILLER METAL = .045” LINCOLN ULTRACORE 71A85
ADDITIONAL SETTINGS =
TIPS:A longer stickout aka contact to work distance CTWD of 3/4” to 1” provides best results Using too short a stickout can result in worm tracks
