Chapter 10 Reference Materials

This chapter contains the parts list of welding power source, and reference materials for setting the welding conditions.

10.1 Parts List

This section shows the parts list of welding power source.

• When placing an order, provide your dealer with the necessary information: the model name of welding power source, the

name of the part to be replaced, and the part number (or specifications if part has no number).

The period of supplying parts will be at the shortest approximately seven years after the welding power source is
manufactured. It may change, however, if the parts from other companies cannot be supplied.

• The codes in the table correspond to those in the schematic diagram/parts layout drawing.
