8.1.1.3 set the spool brake tension by rotating the adjustment screw (19) using an Allen wrench. Clockwise
to increase brake tension, anti-clockwise to decrease brake tension. The spool brake tension should be set
so that the spool can rotate freely, but does not continue to rotate once the wire feed stops. This may need
to be adjusted as the wire is used up and the spool weight decreases.
8.1.2 Loading wire feeder
8.1.2.1 release the wire feeder tension arm (14) by pivoting the wire feed tension adjuster (13) as pictured
below:
8.1.2.4 thread the MIG wire from the spool through the input guide tube (15), through the roller groove
and into the outlet guide tube.
8.1.2.5 Replace the tension arm (14) and the tension adjustment (13). Double check the wire has
located correctly in th e drive roller groove.
8.1.2.6 Adjusting wire feed tension: this is accomplished by winding the knob on the wire tension
adjustment arm (14). Clockwise will increase tension, anti-clockwise will decrease tension. There is a
numbered scale on the tensioner to indicate the position. Ideal tension should be as little as possible, while
maintaining a consistent wire feed with no drive roller slippage. Check all other possible causes of slippage,
such as; incorrect/ worn drive roller, worn/ damaged torch consumables, blocked/ damaged torch feed
liner, before increasing feed tension.
Warning! - Before changing the feed roller or wire spool, ensure that the mains power is
switched off
Warning! - The use of excessive feed tension will cause rapid and premature wear of the drive
roller, the support bearing and the drive motor.
8.1.5. Configuration for the TIG welding process with GAS PROTECTION.
8.1.5.1 The TIG torch power cable (not included) is connected to the negative welding terminal.
8.1.5.2 The gas tube is connected to the gas bottle regulator.
8.1.5.3 Then open the gas bottle valve and the gas regulator valve. We can control the gas flow by
regulating from the valve in the TIG torch.
8.1.5.4 Have the tungsten tip touch the work piece, raise the TIG torch little by little, until you see that
the arc remains stable. You can start welding.
8.1.2.2 check the wire drive roller (16) groove matches the
selected MIG wire type and size. The drive roller will have two
different sized grooves, the size of the groove in use is stamped
on the side of the drive roller. For flux cored 'soft' wire, such as
that used in gasless MIG welding, the drive roller groove has a
serrated profit. For solid 'hard' MIG wire, the roller groove has a
'v' shaped profile
8.1.2.3 the drive roller (16) is removed by threading the drive
roller retainer (17) off in the anti-clockwise direction. Once the
correct drive roller profile is selected, re-fit the drive roller.
