Continued Torch & Wire Feed Set Up for Aluminium Wire

(10) Loosen off the inlet guide tube retaining screw

(11) Remove the inlet guide tube from the front end machine euro connector using long nose pliers.

(12) Carefully feed the extended PA liner section into the inlet guide tube hole of the machine euro

connector

(13) Feed the extended PA liner all the way up and over the drive roller

(14) Tighten the torch euro connection to the machine euro connector

(15) Cut the extended liner with a sharp Stanley knife just in front of the drive roller

(16) Fit an Aluminium contact tip of the correct size to match the diameter of the wire being used

(17) Fit the remaining front end parts to the torch neck ready for welding

(17) Fit the remaining front end parts to the

torch neck ready for welding.

(11) Install a U groove drive roller of the

correct size for the diameter wire being used.

NOTE: MIG 165 not geared

(7) Place aluminium wire onto spool

holder. Feed the wire through the inlet

guide tube on to the drive roller.

NOTE: MIG 165 not geared

(10)Connect the torch to the machine

tighten and secure the torch euro con-

nector to the machine euro connection.

(16) Fit an Aluminium contact tip of the

correct size to match the wire diameter

being used

(12) Press and hold the inch wire button to

feed the wire down the torch cable through to

the torch head.
