To feed the wire from the spool to the welding gun:
1.
Open the pressure arm of the wire feed mechanism and lift the top roll holder to its up
position.
2.
Draw some loose wire from the spool and push it through the straightening rolls at
the back of the mechanism. You can loosen the bottom straightening roll with the
adjustment screw located below it.
3.
Adjust the straightening rolls so that the wire is firmly fed into the drive roll.
4.
Push the wire over the feed roll groove and through the front wire guide until it comes
out from the Euro connector by about 150mm.
5.
Replace the top feed roll holder over the wire and close the pressure arm.
6.
Cut away any deformed wire section and dress the sharp wire tip as described above.
7.
Connect the welding gun and tighten the collar.
8.
Press the Wire inch button and allow the filler wire to feed through the gun cable to the
contact tip.
3.3 Setting the pressure of the feed rolls
To make filler wire run smoothly into the wire liner and to the welding gun you can adjust the
pressure of the feed rolls of the wire feed mechanism.
To increase the pressure
applied to the welding filler wire, turn the black pressure
adjustment knob in a clockwise direction.
To decrease the pressure
applied to the welding filler wire, turn the black pressure
adjustment knob in an anti-clockwise direction.
There is a graduation scale marked on the arm of the adjustment knob. The more pressure
applied, the greater the number of graduation marks visible.
For hard steel and stainless steel filler wires, make sure there is sufficient pressure applied, so
avoiding filler wire slippage in the feed rolls.
NOTE!
Too much pressure may flatten the filler wire, damage its coating, cause friction and
excessive wear to drive roll bearings and therefore reduced life.
3.4 Setting the spool brake force
To prevent the filler wire from uncoiling on overrun following use at high feed speeds, you can
change the brake force of the welding spool.
The spool brake adjustment screw is located inside the spool hub. To adjust the brake force,
unscrew the spool locking mechanism on the tip of the wire spool hub.
To increase the force turn the screw clockwise, and to decrease it, by turn the screw
anticlockwise.
NOTE!
Do not over tighten, and reduce the pressure for light filler wire types.
3.5 Changing the feed rolls
The drive roll has two different sized grooves in it. You can choose which groove to use by
opening the drive roll securing screw and turning the drive roll other way round. The size of
the groove currently in use is facing outward.
