CHAPTER 5
SERVICE
Section I: Calibration
The Model TC-W100A does not require calibration. Component tolerances and stability are such that the
Capacitor Bank Voltage will not vary from Power Supply to Power Supply by more than 4% for the same
WIRE GAUGE SELECTOR setting.
Section II. Troubleshooting
Thermocouple Weld is Dirty or Inconsistent
Return the unit to AMADA WELD TECH. See Section III, Repair Service .
Poor Welds or Failure to Weld
a Improper wire gauge selection.
b Wrong Wire Clamp Jaws for the thermocouple wire size.
c Poor electrical contact to thermocouple wires.
d Heavy oxide or corrosion on the thermocouple wires. Check gas flow. Keep thermocouple in Weld
Chamber for one second before removing.
NOTE:
A dark residue is normal with type J thermocouples.
e Thermocouple wires are different lengths.
f Thermocouple wires are not touching each other at the tip.
g Handpiece is forced past the clamping position during welding.
No Output
Bad Control Board Assembly, Weld Capacitor, or Arc Button or Wire Clamp Solenoid malfunction.
AMADA WELD TECH strongly recommends that the Power Supply be returned to the factory for service.
See Section III, Repair Service.
Thermocouple Stuck in Wire Clamp Tube
If the weld bead is larger than the inside of the Wire Clamp Tube, the thermocouple wire cannot be removed
without first cutting off the weld bead using a flush cutting wire cutter or a sharp knife. Avoid cutting or
nicking the Wire Clamp Tube.
