1.Power Switch - Place the lever in the “ON” position to energize the machine. When the power is on, the fan will operate and the output will be energized in SMAW modes. GTAW mode requires remote trigger to energize the output.
2.Output Control - This controls the output current. Control is provided over the entire output range of the power source with 1 turn of the control knob. This control may be adjusted while under load to change power source output. When using remote control this function becomes the limit setting.
3.Local/Remote Switch - Place in the “LOCAL” position to allow output adjustment at the machine. Place in the “REMOTE” position to allow output adjustment at remote pot or amptrol. In Remote, the machine output control pot is the limit setting for remote control.
4.Mode Switch
GTAW Optimized for touch start use. Triggering at amphenol is required using an Arc Start Switch, Amptrol or similar means. Short circuit current is limited to approx- imately 25 amps to aid in touch starting.
CCSoft Best for EXX18 thru EXX28 stick electrodes. Output energized when machine is on.
CCCrisp Use this mode for stick welding with EXX10 thru EXX14 electrodes. Output energized when machine is on.
5.Hot Start - Controls the amount of starting energy in SMAW. The Hot Start setting will set the amount of extra power given during the initial strike.
A Hot Start setting of 100% will give you an additional striking current 100% above the welding set current*. (Striking current in this example will be 200% of the set current). For a Hot Start setting of 100%, the current will decrease back to the set current in one second.
AHot Start setting of 50% will give you an additional striking current 50% above the welding set current*. (Striking current in this example will be 150% of the set current). For a Hot Start setting of 50%, the current will decrease back to the set current in .5 second.
* The maximum striking current is 300 Amps.
