Note:
The welding duty cycle is the percentage of actual continuous welding time that can occur in a ten minute cycle.
For example: 15% at 200amps - this means the welder can weld continuously at 200 amps for 1.5 minutes and
then the unit will need to be rested for 8.5 minutes. The duty cycle can be affected by the environment in which
the welder is used. In areas with temperatures exceeding 40 degrees, the duty cycle will be less than stated. In
areas less than 40 degrees, higher duty cycles have been obtained.
All tests on duty cycles have been carried out at 40 degrees with a 50%. So in practical working conditions the
duty cycles will be much greater than those stated above.

INSTALLATION
5.1 MIG Welding Set Up & Operation
5.1.1 Fitting the spool
5.1.1.1 Open the cover door for the wire feed compartment. Remove the wire spool retainer (24) by
threading off anti clockwise.
5.1.1.2 Fit the 200mm diameter wire spool to the spool holder, ensuring the end of the wires exits towards the
wire feeder from the bottom of the spool. Ret the wire spool retainer (25) and tighten hand tight.
5.1.1.3 Set the spool brake tension by rotating the adjustment screw (26) using an Allen Key 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.
5.1.2 Loading wire feeder
5.1.2.1 Release the wire feeder tension arm (21) by pivoting the wire feed tension adjuster (20) as pictured
below.
5.1.2.2 Check the wire drive roller (23) 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 ux
cored ‘soft’ wire, such as that used in gas less MIG welding, the drive roller groove has a serrated prot. For solid
‘hard’ MIG wire, the roller groove has a ‘v’ shaped prole.
5.1.2.3 The drive roller (23) is removed by threading the drive roller retainer(24) off in the anti-clockwise
direction. Once the correct drive roller prole is selected, re-t the drive roller.
5.1.2.4 Thread the MIG wire from the spool through the input guide tube (22), through the roller groove and into
the outlet guide tube.
5.1.2.5 Replace the tension arm (21) and the tension adjustment (20). Double check the wire has located
correctly in the drive roller groove.
5.1.2.6 Adjusting wire feed tension: this is accomplished by winding the knob on the wire tension adjustment
arm (20). 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.

INSTALLATION
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.
!
5.1.3 Loading wire feeder
5.1.3.1 Connect the MIG Torch Euro Connector (28) to the torch socket on the front of the welder (11).
Secure by rmly hand tightening the threaded collar on the MIG Torch Euro Connector clockwise.
5.1.3.2 Check that the correct ux cored, gas less wire, matching drive roller (23) and welding tip (32)
are tted.
5.1.3.3 Connect Torch Connection Power Lead (14) to the negative (-) welding output terminal (13).
5.1.3.4 Connect Earth Lead Quick Connector (30) to the positive (+) output welding terminal (12).
See picture below:
5.1.4 Setup for gas shielded MIG welding operation
5.1.4.1 Connect the MIG Torch Euro Connector (28) to the torch socket on the front of the welder (11).
Secure by rmly hand tightening the threaded collar on the MIG Torch Euro Connector clockwise.
5.1.4.2 Check that the correct gas shielded wire; matching drive roller (23) and welding tip (32) are tted.
5.1.4.3 Connect Torch Connection Power Lead (14) to the positive (+) welding output terminal (12).
5.1.4.4 Connect Earth Lead Quick Connector (30) to the negative (-) output welding terminal (13).
See picture below:
5.1.4.5 Connect Earth Clamp (29) to the work piece. Contact with work piece must be strong contact with
clean, bare metal, with no corrosion, paint or scale at the contact point.
5.1.4.6 Connect the gas regulator (optional) and gas line to the inlet on the rear panel (18). If the regulator is
equipped with a ow gauge, the ow should be set between 8 – 15 L/minute depending on application. If gas
regulator is not equipped with a ow gauge, adjust pressure so gas can just be heard coming out of the torch
conical nozzle (31). It is recommended that gas ow is checked again, just prior to starting weld this can be
done by triggering the MIG torch with the unit powered up.
