Front Panel Operation
Units may be used either with the standard torch (supplied with them) or with the Spool Gun.
Welder Controls
1. Main ON/OFF switch and welding voltage adjustment:
2. Wire feed adjustment knob
To increase the wire speed, turn the potentiometer
clockwise; to decrease the wire speed, turn it counter-
clockwise. The same procedure decreases the
values on the welding parameters. Turn knob slowly.
3. Overheating indicator (yellow)
This LED blinks when unit is overheating. It will light up when thermostatic protection shut
down the machine and will cease blinking only after the machine has cooled sufficiently to
continue welding.
4. Ground Clamp
5. MIG Torch/Gun
Remove for spool gun change and disconnect gas and electrical connector. Reconnect gas and
electrical connector after change over.
Welding Preparation
• Connect the ground cable to the proper female outlet on the bottom right-hand corner of the
welder (on some models the ground cable is already connected). Attach the ground clamp to
the bare metal to be welded, making sure of good contact;
• Make sure that the wire-roller groove in the roller corresponds to the diameter of the wire
being used.
• Plug the machine into a suitable outlet.
• Open the gas valve on the gas cylinder regulator, (turn knob clockwise) and adjust the gas
regulator to the proper setting position. Note: this varies with different metals, thicknesses and
currents.
