One of the great things about dual shield flux core is that much less cleaning and prep work is needed before welding on hot rolled carbon steel.
Dual shield flux core creates a much lighter layer of slag than stick welding and its easy to remove with a rake of a chipping hammer.
Pulse spray mig is also great process that can be used in all positions but the main problem with pulse spray is that not all mig welding machines have the capability for pulse spray.
A basic mig welding machine without pulse features works just fine for dual shield flux core welding.
WELD PROCESS = DUAL SHIELD FLUX CORE, FCAW-G ( GAS SHIELDED)
METAL TYPE = CARBON STEEL
THICKNESS = 3/8” WALL TUBE TO 1/4” PLATE
WELD TYPE = FILLET
JOINT TYPE = TEE
POSITION = 2F HORIZONTAL
VOLTS = 22.9 volts
WIRE SPEED = 345 IPM
WIRE SIZE = .045” LINCOLN 71M

TIPS: VERY LITTLE MANIPULATION NEEDED.
CTWD (CONTACT TO WORK DISTANCE) SHOULD BE 3/4”-1” 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
