Attaching the Shielding Gas Hose and Regulator

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.

1 Connect the hose to the

welder gas intake barb
and secure in place with
the appropriate hose
clamp.

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.

• Check with your local gas supplier for their recommendations

of the required gas mixture and ow 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.

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

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

using the 5kg coil adaptor.

1 Open the side cover

by lifting the side
cover release lever.

2 Remove the wing nut by

rotating anti-clockwise and
remove the drive washer.

3 If a 5kg wire coil is

to be tted, slide the

coil adaptor onto
the wire drive shaft.

Note: This step can

be skipped if a smaller

wire coil is to be tted.

4 Slide the welding wire coil

onto the shaft.

5 Align the drive

washer lug with
the slot in the drive
shaft and secure
with the wing nut
but do not over
tighten.

Note: Over tightening of the wing nut will restrict the wire feed

rate and can cause damage to the wire feed motor or irregular
welding.
