Changing the Feed Roll
The wire feed roller is factory set for welding filler wires 0.8 – 0.9mm (.030” - .035”). The
roller has a 0.6mm (.023”) diameter groove on the other side; therefore, the feed roller side must
be changed if you use 0.6mm thick filler wire. In order to thread the filler wire, follow these steps:
1.
Open the wire cabinet housing by pressing on the opening button and install the wire spool
in such a way that it rotates counter clockwise. You can use either a diameter 200mm (8”)
or 100mm (4”) wire reel in the machine.
2.
Attach the reel onto the spool holder being sure to locate drive detent on 200mm (8”) reels
and be sure to install spring pressure plate directly under tension nut.
3.
Unfasten the wire end from the reel, but hold on it all the time.
4.
Straighten the wire end 20 cm out and cut the wire in the straightened location.
5.
Open the pressure control level which then exposes the drive roll wire groove.
6.
Thread the wire through the wire’s rear guide, over the roller making certain it aligns with
groove, feed 10 cm into the gun’s wire guide.
7.
Close the feed gear and fasten it with the pressure control lever. Make sure that the wire
runs in the feed roll groove.
8.
Adjust the compression pressure with the pressure control lever no higher than to the
middle of the scale. If the pressure is too high, it removes metal fragments from the wire
surface and may damage the wire. On the other hand, if the pressure is too low, the feed
gear slips and the wire does not run smoothly.
9.
Make sure the gun nozzle and contact tip are removed.
Note
：
When driving the wire into the gun, do not point the gun at yourself or others.
10.
Press the welding gun trigger to feed the wire into the gun. Once it extends out, reinstall tip
using wrench to tighten. Reinstall nozzle.
