TC-W100A - THERMOCOUPLE WELDER
4-2 990-070
Section II. Weld Chamber Maintenance
Over time, the thermocouple weld bead will become dirty in appearance, signaling an undesirable buildup
of thermocouple weld material on the Arc Button located inside of the Weld Chamber. If the Arc Button is
not periodically resurfaced, the weld quality will deteriorate to where a weld cannot be made.
The buildup rate depends on the number of thermocouple welds made, the thermocouple wire material, and
the thermocouple wire diameter. Buildup occurs faster with large gauge wires such as 20-22 AWG and
usually appears as a bright metallic deposit on the face of the Arc Button.
Should this occur, return the unit to AMADA WELD TECH. See
