3a. Welding Power is Available BUT is Not Adjustable -- Control Models WC.12RO & WC.24RO
3a.1 With the engine OFF, open the Control Module and observe Lamp #2 and
Lamp #3 while holding the Control Handle Power Button “down” and rotating
the Control Dial on the Control Handle.
If Lamp #3 changes in intensity while Lamp #2 does not OR if Lamp #2
changes in intensity while Lamp #3 does not, your Control Module is
malfunctioning. Go to Step 3a.4.
If both Lamp #2 and Lamp #3 change in intensity, your problem is either in the
Power Generator or the Control Module. Go to step 3a.2.
If both Lamp #2 and Lamp #3 maintain a constant light intensity, either the
Control Handle Assembly or the Control Module the is malfunctioning. Go to
step 3a.3.
3a.2 You can easily check for a component failure in the Power Generator by
disconnecting the two Gray wires which are used to connect the Control Module
to the Power Generator’s control terminals, and check in the electrical
resistance between these control terminals with an ohm meter. A normal
reading is between 1.4 and 2.4 ohms. If your meter shows a resistance of
less
than 1.4 ohms , your Power Generator has a component failure, and must be
returned for repair. Go to Step 3a.4.
If the electrical resistance measured between the control terminals is
higher
than the “normal” range of 1.4 to 2.4 ohms (for example, 10 ohms or 20
ohms or more) it is an indication of grease or some similar material which has
caused “fouling” coating of the brushes and or internal slip-rings. Cleaning can
be accomplished in the field, if necessary, but is best done under factory
conditions. Such cleaning, will be performed free of any labor charge, with
charges only for return freight cost. Go to Step 3a.4.
If your electrical resistance between the control terminals is correct, you should
also measure the electrical resistance between either of the terminals and the
case of the Power Generator. A normal reading is an “open” circuit (an infinite
resistance). If your meter shows any measurable resistance, your Power
Generator has a component failure, and must be returned for repair. Go to Step
3a.4.
If all resistance readings at the control terminals were found to be “normal” you
have a Malfunctioning Control Module, reconnect all wires, and go to step 3a.4.
3a.3 If Lamp #2 and Lamp #3 maintain a constant light intensity, either the Control
Handle Assembly, or the Control Module, or the Control Cable connection
between the two assemblies is malfunctioning.
NOTE: If you are using a cable extension, or a quick disconnect system, of any
sort, with your welder, remove it temporarily and repeat the tests to insure that
the problem noted is not caused by a fault in the cable extension.
To determine if the Control Cable connection is at fault, temporarily hold down
the Power Button (you may need an assistant to do this) and observe the
behavior of Lamp #2 and Lamp #3 while you partially unplug and re-plug the
two black Control Cable connectors which connect the Control Handle to the
Control Module. If Lamp #2 and Lamp #3 “flicker”, go off, or change in
intensity as you do this, the connection is faulty -- either due to a broken wire, a
