3-4-1. Weld Output Connections

To obtain full rated output from this unit, it is necessary to select, prepare, and install proper weld
cables. Failure to comply in any of these areas may result in unsatisfactory welding performance.

A. WELD Cable Selection
Use the following guidelines to select weld cables:
1. Use the shortest possible cables, and place cables close together.
Excessive cable lengths may reduce or cause unit overload due to added resistance.
2. Use weld cable with an insulation voltage rating equal to or greater than the maximum open-circuit
voltage (OCV) of the welding power source.
3. Select welding cable size according to maximum weld output and total length of connecting cables
in weld circuit. For example, if a 7.5mm electrode holder or torch cable is used with a 7.5m work
able
4. Do not use damaged or frayed cables.
Rated current in A
(60% duty cycle)
Table 1 - Relation between size range and rated current
1. The Current is rated for 60% and 100% duty cycle
2. Welding cables, the coverings of which are not capable of withstanding a
conductor temperature of 85 ℃ , will be damaged if the coupling devices
are used at the rating given above at an ambient air temperature of
40 ℃ .
