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-



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.


Genuine TWECO contact tips should be used.


Loose welding terminal connections can cause overheat-

ing and result in the cables being fused to the welding


(8) The wire reel hub incorporates a friction brake

which is adjusted during manufacture for opti-

mum braking.
