1. POWER SWITCH & LIGHT - Turns power on or

off

to the welder. When switched “ON”, the

cooling fan runs and the light will illuminate indicat- ing that the power is on.

2.TIG/STICK SWITCH - Selects the mode of output, either TIG (GTAW) or Stick (SMAW). Refer to

Welding in TIG Mode and Welding in Stick Mode later in this chapter for information on how the machine functions in each of these modes.

3.POLARITY SWITCH - Allows you to select between

welding in AC , DC - , or DC+ polar- ity. In DC + polarity the electrode is positive and the work clamp is negative. Use DC + for most stick welding. In DC - the electrode is negative and the work clamp is positive. Use DC - for TIG welding stainless steel and mild steel. AC polarity is recom- mended for TIG welding aluminum.

CAUTION

Do not switch the polarity switch while welding or damage may result to the

machine.

------------------------------------------------------------------------

4.CURRENT CONTROL - This control is active in both TIG and Stick modes. In Stick mode the cur- rent control sets the welding current. In TIG mode this control sets the maximum current. The Amptroltm will adjust the welding current from the machine min- imum to this maximum setting.

5.OVER TEMPERATURE LIGHT - If the welder overheats due to blocked air flow, high ambient air temperature, or exceeded duty cycle, an internal thermostat will open disabling the welding output and this yellow light will illuminate. The cooling fans will continue to run to cool the unit during this time. The light will go out when the unit cools and the thermostat resets.
