Operating Instructions
A. Preparation for Welding
Mount the spool of welding wire on the spool
adapter so the wire will be pulled from the low
side of the coil. Adjust the friction brake on the
wire spool by adjusting the screw in the center
of the spool. If adjusted properly, the spool will
feed smoothly and will not coast or continue to
spin when feeding stops.
Debur the end of the wire, then insert it into the
inlet guide through the feed rolls and the outlet
guide. (Refer to Figure 3).
Press the power switch to the “On” position
and feed the wire into the conduit by press-
ing “Forward” key. Continue to feed the wire
through the conduit and the wire guide tip until
a desired amount extends beyond the tip.
See the Quick Start Guide for various jog
modes.
B. Operation
9629 Control:
The operation of a CWF-50 is not difficult. The
following sequence is suggested:
1.
Turn on power to unit.
2. Using the Forward key, inch the wire
forward a little. Trim the wire if there is
a ball on the end of the wire. This step is
especially necessary if feeding wire and
using an arc length control. A ball on the
end of the wire could touch the tungsten
when feeding initially. If the wire con-
tacts the tungsten, you will get a “ball”
on the end of the tungsten. The operator
should stop the weld and resharpen the
tungsten. This action could also cause
adverse effects with the arc length con-
trol.
When the wire is inched forward, this is
a good time to verify the wire’s position.
Adjust if necessary.
3. Retract wire to desired starting position
using the Reverse key.
4. Check wire and wire spool briefly. Veri -
fy there is enough wire for the next weld
and that the wire is not wrapped around
the spool holder.
5. Check wire feed speed setting, the start
delay setting, and the stop retract setting.
These settings are critical to achieve the
desired weld.
6. At this point, the unit is ready to feed
wire. If the starting and stopping of the
wire is controlled remotely, the control
will go through the start delay. Once
this delay has timed out, the unit will
proceed to feed wire at the rate set on
the dial.
When the remote start signal quits, the
unit will go through the stop delay, then
stop. The unit then proceeds to enter the
wire retract time, pulling the wire out of
the weld zone. This action prevents the
wire from sticking in the weld puddle at
the end of the weld.
Note: If the retract time is set too long,
the wire could retract up into the wire
tip. If this happens, the wire could, on
occasion, get stuck on the tip on the next
weld.
