- Release the wire end from reel and cut off the bent length.
Be careful that the wire does not unwind and spill from the reel!
Straighten about 20 cm of the wire and see that the end of it has no sharp edges
(file off if necessary). A sharp edge may damage the wire guide tube and contact
tip of the welding gun.
- Draw a bit of loose wire from reel. Feed wire through back liner to feed rolls.
Don't release pressure of feed rolls!
- Press the wire drive switch S11 or the gun switch and feed a bit wire until wire goes through
feed rolls to gun.
See that wire is in grooves of both feed roll pairs!
- Press still the wire drive or the gun switch until wire has come through contact tip.

rolls and feed wire manually through feed rolls.
2.2.5. Adjustment of pressure
Adjust the pressure of feed rolls with the control screw (20) so that the wire is fed into the wire
guide tube evently and allows a little braking when coming out from the contact tip without
slipping at the feed rolls.
Excessive pressure causes flatening of the filler wire and damage to the coating.
It also causes undue wear of the feed rolls as well as friction.
2.2.6. Adjustment of tightness of reel brake
Brake force is adjusted through hole in locking device of reel hub by screwing the control screw
(41) with screwdriver.
Adjust the brake force to a point where the wire reel will not continue to overrun once the drive
motor has stopped. If this is too loose the wire will spill from the reel. If this is too tight the
brake puts excess load on the wire drive motor. The brake force may be different for high wire
feed speeds and the varied weights of the wire reels and filler materials.
2.2.7. Burn back time
Electronics of the unit controls stopping of welding automatically so that the wire end doesn't
melt to fastened to the contact tip or the work piece. Automatics work regardless of the wire feed
speed. End automatics eliminate also forming so-called "ball" at wire tip, disturbing next start.
