OPERATION

3.1.6 Over Temperature Indicator (Temp)

This amber light will indicate when an internal overheat- ing condition has occurred and one of the thermal switches has opened. User control of the solid state contactor will be interrupted and power source output will shut down to protect critical components. Once cooled to a safe temperature, the thermal switch will automatically reset and output control will be restored.

3.1.7 Voltmeter and Ammeter

A digital voltmeter and ammeter provides an accurate indication of dc output voltage and current.

3.1.8 Fault Indicator

If an optional External Ground Conductor Protection Kit was installed, this red light, when lit, will indicate that current was flowing through the external ground con- ductor. The power source output termirals are deenergized and the fault must be corrected before resuming operation.

3.2 OPERATION SET-UP

Prior to performing the steps below, open the wall disconnect switch or remove the fuse from the fuse box to electrically isolate the power source.

ELECTRIC SHOCK CAN KILL! "Machinery Lockout Procedures" should be employed. If it is not pos- sible to use padlocks, attach a red tag to the line disconnect switch (or fuse box) warning others that the circuit is being worked on.

3.2.1Stick Welding (SMAW) Air Carbon Arc Goug- ing (ACAG) and Scratch Start Tig Welding (GTAW)

A.If stick welding or arc gouging, connect work cable to the workpiece and to the negative (-) terminal of the power source. Connect torch cable to the positive (+) terminal of the power source.

If Tig welding, connect work cable to the workpiece and to the positive (+) terminal of the power source. Connect Tig torch cable to the negative(-) terminal of the power source.

B.Place the Power ON-OFF switch to the ON position or close the main(wall) disconnect switch.

C.Adjust the current control on the power source to the approximate desired welding current.

D.If stick welding, set the Arc Force control at 3 or

4on the dial and readjust as necessary to obtain a softer or harder welding arc.

For air gouging or Tig welding, set Arc Force control at zero (0).

E.If using a remote current control, such as HC- 3B, place current and contactor switches in REMOTE positions. Note that the current range will be limited to the maximum setting on the power source's current control dial.

If not using remote current control, place current switch to PANEL and contactor switch to ON.

F.Place the Power ON-OFF switch to the ON position.

G.To preset the approximate welding current, pro- ceed as follows:

1.Connect the electrode holder to the workpiece to create short.

2.Place the contactor switch to the ON posi- tion.

3.Set the Arc Force control to the minimum position.

4.Place the Power On-Off switch to the ON position.

5.By observing the digital ammeter,adjust Current Control to the desired current set- ting.

6.Place Power On-Off switch back to OFF

7.Then remove the holder from the work- place.

H.After setting the desired current and if using remote, turn switch back to REMOTE.

I.You are now ready to begin welding.

3.2.2Mig Spray Am (GMAW) and Flux Cored (FCAW) Welding with "Off the Are" Wire Feeder.
