Wire Feed Setup
Once you have verified proper drive roll installation
it is time to set up the wire feed. Setting up the wire
feed consists of three parts:
x
Installing Wire Spool
x
Feeding the Wire
x
Adjusting the Wire Arms
Wire Spool Installation
To install the wire spool, start by unscrewing the red
hub nut from the wire hub (see Figure 26
– Hub
Nut).
FIGURE 28 – HUB NUT
Place the wire spool over the wire hub and thread
the hub nut back over the spool until it is hand tight.
Turn the spool by hand to check the friction. If the
spool can spin too freely then it may unwind on its
own. Tighten the thumb nut on top of the wire hub
to increase the rotational friction.
FIGURE 29 – THUMB NUT
Install the wire spools so that the wire is fed from
the outside of the spool into the wire feeder (see
Figure 28
– Wire 1 Installation and Figure 29 – Wire
2 Installation).

Feeding the Wire
The wire feed unit is specially designed to be self-
feeding without jamming or binding.
1. Cut
wire cleanly.
2. Turn on the wire feed motor in the forward di-
rection.
3. Take the end of the wire from the spool and
feed it through the inlet guide on the wire feed
unit until the rollers catch and pull (see Figure
30
– Inlet Guide).
4. The wire should be fed all the way through the
wire liner and come out the wire guide tip at the
torch.
5. While the wire is feeding watch the wire to
make sure it is not slipping. If it is slipping tight-
