6.13  Calibration

1. Calibration

Art # A-11822

Figure 6-12: Calibration

While the power source is turned off, set SW1 position 2 to ON, to allow calibration 
of output volts & amps.

2.  Output Current Calibration

1.  Select STICK mode on the front panel.
2.  Connect a load to the output terminals. The load should be of a resistance to give between 20V – 25V 

at 170A.

3.  Set front panel AMPS control to minimum.
4.  Adjust Imin trimpot until output amps is 5A +/- 0.5A
5.  Set front panel AMPS control to maximum.
6.  Adjust Imax trimpot until output amps is 170A +/- 1A
7.  Recheck settings
8.  Set front panel AMPS control to maximum.
9.  Adjust A potentiometer so Amps display reads within 0.5A of the measured value.
10.  Press the front panel AMPS control for > 2 seconds, so that the meter displays weld volts.
11.  Disconnect the load from the output terminals
12.  Measure output welding voltage and adjust WVF potentiometer so Volts display reads within 0.1V of 

the measured value.

13.  Press the front panel AMPS control for > 2 seconds, so that the meter displays weld amps.
14. Turn off the mains power off to the machine.
15. Set SW1-2 back to the OFF position.

3.  Remote Calibration

1.  Select LIFT TIG mode on the front panel.
2.  Remove the load from the output terminals.
3.  Set front panel AMPS control to maximum.
4.  Connect a remote control device and set the remote control potentiometer to maximum.
5.  Adjust the CAL REMOTE trimpot until the display starts to fall below 170A
6.  Slowly adjust the CAL REMOTE trimpot until the display is “just” reading 170A +/- 0A.
