Wire feed Unit Diagram
1. Wire inch button – press button and wire feed rollers will start to allow wire to come
through tip ready for welding.
2. Wire tensioners
-
Do not over tighten wire feed pressure rollers as this can cause
premature motor and roller failure.
Correct way to adjust tensioners is to slacken off pressure so that wire does not feed,
slowly adjust pressure until wire feeds smoothly, you should be able to stop wire
feeding by holding wire and it should slip on rollers.
If you have too little pressure wire will slip when welding causing unwanted Burn back
into tips
If you have too much pressure wire can snag in rollers when wire hits work and cause
wire tangle by rollers.
3. Top pressure rollers, release wire tensioners and arms will move up to allow wire to be
installed.
4. Main rollers – these can be removed by un-screwing retaining screws – ensure correct
size roller is fitted according to wire size on reel.
