Flux-Cored Arc welding (FCAw)

This process also known as Open Arc, Innershield, FAB

Shield, etc., is an electric arc welding process which fuses

together the parts to be welded by heating them with an

arc between a continuous flux filled electrode wire and

the work. Shielding is obtained through decomposition of

the flux within the tubular wire. The process is normally

applied semi-automatically; however the process may be

applied automatically or by machine. It is commonly used

to weld large diameter electrodes in the flat and horizontal

position and small electrode diameters in all positions. The

process is used to a lesser degree for welding stainless

steel and for overlay work.

WARNING

Follow these instructions only after referring to the Safety

Instructions and Warnings chapter of this manual, and

the instructions in the Installation chapter

Check List Before Starting

Wire Feed Speed – 1 to 10
Voltage Range Switch Setting – MIN or MAX
Electrode Wire Stick-out – approx 3/8” (10mm)

4.06 Welding Gun Positions

The welding gun should be held at an angle to the weld

joint. Hold the gun so that the welding seam is viewed

at all times. Always wear the welding helmet with proper

filter lenses.

CAUTION

Do not pull the welding gun back when the arc is

established. This will create excessive wire extension

(stickout) and make a very poor weld.

The electrode wire is not energized until the gun trigger

switch is depressed. The wire may therefore be placed on

the seam or joint prior to lowering the helmet.
