The MIG welder is supplied with a 0.2kg coil of 0.8mm gasless 

welding wire. Welding wire up to 5kg can be fitted to this welder 

using the 5kg coil adaptor.

2.  SHIELDED GAS WELDING SETUP

3.  FITTING THE WELDING WIRE COIL

Attaching the Shielding Gas Hose and Regulator

1   Connect the hose to the 

welder gas intake barb 

and secure in place with 

the appropriate hose 

clamp.

2   Remove the wing nut by 

rotating anti-clockwise and 

remove the drive washer.

4   Slide the welding wire coil 

onto the shaft.

When using a shielding gas with the MIG welder, you will 

require additional hoses and gauges. These additional 

accessories are available at your local gas supplier and are not 

included with your MIG welder.

•  Check with your local gas supplier for their recommendations 

of the required gas mixture and flow rate for your MIG welder.

•  Check all of the connections to the gauges and the shielding 

gas bottle for leaks prior to commencing to weld.

2   When using a 

shielding gas with 

a disposable argon 

gas bottle, you may 

need to purchase 

a hose reducing 

adaptor from your 

gas supplier.

3   If a 5kg wire coil is 

to be fitted, slide the 

coil adaptor onto 

the wire drive shaft.

Note:

 This step can 

be skipped if a smaller 

wire coil is to be fitted.

1   Open the side cover 

by lifting the side 

cover release lever.

5   Align the drive 

washer lug with 

the slot in the drive 

shaft and secure 

with the wing nut 

but do not over 

tighten.
