Operation
4.02 FirePower Controls
Refer to Figure 4-1
1. Power ON / OFF switch turns the power on and
off. It also lights when the power supply has gone
into overtemp.
2. The Wire Speed Control knob controls the welding
current via the electrode wire feed rate (i.e. the
speed of the wire feed motor).
3. The Voltage Power Switch selects between MIN
and MAX voltage levels to the welding termi-
nals.
CAUTION
The Voltage Power Switch MUST NOT BE SWITCHED
during the welding process.
4. Welding Torch and Cable
5. The Work Cable & Clamp connects to the item
being welded.
6. Main Power Cable.
7. The moveable tension knob applies pressure to
the grooved roller via screw-adjustable spring
pressure. The adjustable spring screw should be
adjusted to a minimum pressure that will provide
satisfactory wire feed without slippage. If slip-
ping occurs, and inspection of the wire contact
tip reveals no wear, distortion or burn-back jam,
the conduit liner should be checked for kinks and
clogging by metal flakes and slag. If this is not
the cause of slipping, the feedroll pressure can
be increased by rotating the adjustable spring
screw clockwise. The use of excessive pressure
may cause rapid wear of the feed roller, motor
shaft and motor bearings.
NOTE
Genuine TWECO contact tips should be used.
CAUTION
Loose welding terminal connections can cause overheat-
ing and result in the cables being fused to the welding
terminals.
(8) The wire reel hub incorporates a friction brake
which is adjusted during manufacture for opti-
mum braking.
