Check the problem against the symptoms in the following troubleshooting guide. The remedy may be quite simple. If the
cause cannot be quickly located, shut off the input power, open up the unit, and perform a simple visual inspection of all the
components and wiring. Check for secure terminal connections, loose or burned wiring or components, bulged or leaking
capacitors, or any other sign of damage or discoloration.
The cause of control malfunctions can be found by referring to the sequence of operations and electrical schematic diagram
(Figure 5-1) and checking the various components. A volt-ohmmeter will be necessary for some of these checks.

a. power light (pl1) does not come on.
1. Visually inspect the machine for any damage.
2. Check if the cooling fan is running. If not, then check the following :
a. Check if the machine power cord is plugged to the input power receptacle.
b. Measure the input power at the receptacle. If not present, then check the wall
disconnect switch and it’s fuses.
c. Check Fuse (F1). If fuse is ok, then check the input circuit breaker (CB1) for proper operation. Replace if defec-
tive.
3. If above items check OK , the problem is internal. Send unit to an Authorized Repair Station for repair.
a. If the cooling fan is running, then measure voltage between pins P2-11 and P2-14 of the control board
(should be 115 VAC). If there is no voltage, then replace transformer T2.
b. If the voltage is present, then the pilot light may be burnt out.
B. no air flow
1. Check air inlet supply. Unit requires 360 CFH at 75 psig.
2. Check air hose and connections. Tighten if leaking.
3. Does air flow when “air test” switch is in test position?
a. If not, check torch consumables, replace if necessary.
b. If above items check OK , the problem is internal. Take unit to an Authorized Repair Station for repair.
