20. Wire feed

Replacement of the wire feed roll
(4)
For the wire used, the wire feed roll
with the appropriate groove has to
be used respectively.
To replace the wire feed rolls, the
knurled screw (5) has to be
unscrewed.
It must be ensured that the groove
of the wire feed role forms an
alignment with the wire guide pipes
(6).
The wire feed rollers have two diameters on a single roller. That means that when installing the rollers, it must be
ensured that the right groove is used. This is the case if the used wire diameter can be read on the roller.
The pressure point of the wire feed role must be configured with the spring pressure unit (7) in such a way
that the wire is fed evenly if the hose assembly is stretched out, on the one hand, and does not kink on the other.
It should slide out if the wire is stuck at the contact tip outlet.
Reel brake
The wire mandrel (2) is equipped with a reel brake that prevents the wire reel (3) from overshooting if the wire
feed motor comes to a halt. By turning it to the right, the hexagon socket screw (1) can increase the braking
power.
Feed of the wire in the torch hose assembly
The frictional resistance of the welding wire is increased in the wire liner in relation to the length of the hose
assembly. The torch hose assembly should therefore be no longer than required.
When processing aluminium welding wire, it is recommended to replace the wire liner with a teflon wire guide.
The length of the torch hose assembly should not be longer than 3 m.
It is recommended to blow out the wire liner and the wire guide line pipe after welding of a roll of wire using
compressed air. The slippage of the wire liner will worsen depending on the amount of wire required and the wire
properties. If an obvious wire feed fault is noticed, the wire liner shuold be replaced.
