1INPUT POWER SWITCH AND PILOT LIGHT - Turns the input power to the TIG Module on and off. Red pilot light indicates that input power is “on”.
2HIGH FREQUENCY SWITCH - Used to select Continuous High Frequency, Start Only High Frequency, or High Frequency Off.
3AFTERFLOW CONTROL - Adjust the afterflow time from 5 to 55 seconds. This is the time the shielding gas (and, if equipped, cooling water) flows after the weld is completed. This extra gas flow cools the TIG torch and the tungsten electrode.
4CURRENT CONTROL - This control functions only when the TIG module is used with a power source having remote control capability. It controls the welding current, and is used in conjunction with the Local/Remote Switch.
5LOCAL/REMOTE SWITCH - This switch functions only when the TIG module is used with a power source having remote control capability. When in the Local position, all output current control is done by the Current Control on the TIG Module. When in the Remote position, the Current Control on the TIG Module sets the maximum available welding current, and an Amptrol, plugged into the Amptrol Receptacle, can adjust the welding current. See the Chart labeled “Use of the Current Control, Arc Start Switch and Amptrol on Ranger Welders with Remote Control.
