CALIBRATION PROCEDURE

(Stick and Wire Model Only)

1.Set the front control panel as follows:

”Control” dial to 0 (Min.).

“Range” dial to the ‘Wire Welding’ setting. “Idler” switch in the “Auto” position. “Volts/Amps” switch to the ‘volts’ position. “Output Control switch to the “Welding Terminals Remotely Controlled” position.

2.Connect the volt/ohm meter across the “+” and “- WIRE” (CV) terminals.

3.Start the unit.

WARNING

While the unit is running there are high voltages present inside the control

box. THE VOLTAGES ARE HIGH ENOUGH TO KILL. Keep hands out of

the control box while the unit is running.

4.As the unit begins to run, the display will step quickly through its initialization sequence. As soon as the display shows three dashes (“---”) begin to toggle the “Idler” switch from “AUTO” to “HIGH”. You must toggle the switch a total of 5 times in 5 seconds from the time that the dashes appeared on the display. Failure to due so will result in the unit default- ing to normal operation. The switch must be returned to the “AUTO” position once the test mode has been accessed. The display should read “000”, indicating the step number of the self test to be executed.

5.Toggle the “idler” switch to “HIGH” and back to “AUTO.” The display should read “001.”

6.Toggle the “idler” switch to “HIGH” and back to “AUTO.” The display should read “002.”

7.Toggle the “idler” switch to “HIGH” and back

to “AUTO.” The display should read “003.”

8.Set the Output Control switch to the “WELD- ING TERMINALS ALWAYS ON” position.

9.Turn the “Control” dial until the display reads “19.0.” Assure that there is no load applied to the unit.

10.Toggle the “Idler” switch to “HIGH” and back to “AUTO” continually until the voltage on the voltmeter across the studs reads 19.0 ± .2 volts. If 19.0 ± .2 volts is passed by, continue to toggle the “Idler” switch to “HIGH” and back to “AUTO” and the voltage will eventually wrap around to a value below 19 volts. Continue to toggle the “idler” switch and try to attain 19.0 ± .2 volts again. Once the voltage across the terminals does read 19.0 ± .2 volts, proceed to the next step.

11.Set the Output Control switch to the ‘WELD-

ING TERMINALS REMOTELY CON- TROLLED” position.

12.You have now completed the calibration pro- cedure. Disconnect the volt/ohmmeter.
