3.04 Electrical Input Requirements
Operate the welding power source from a single-phase
50/60 Hz, AC power supply. The input voltage must match
one of the electrical input voltages shown on the input
data label on the unit nameplate. Contact the local electric
utility for information about the type of electrical service
available, how proper connections should be made, and
any inspection required.
The line disconnect switch provides a safe and convenient
means to completely remove all electrical power from
the welding power supply whenever necessary to inspect
or service the unit.
Do not connect an input (BROWN or BLUE) conductor to
the ground terminal.
Do not connect the ground (YELLOW/GREEN) conductor
to an input line terminal.
Refer to Figure 3-1 and:
1. Connect end of ground (YELLOW/GREEN) conductor
to a suitable ground. Use a grounding method that
complies with all applicable electrical codes.
2. Connect ends of line 1 (BROWN) and line 2 (BLUE)
input conductors to a de-energized line disconnect switch.
3. Use Table 3-1 and Table 3-2 as a guide to select line
fuses for the disconnect switch.
Table 3-1: Electrical Input Connections
NOTE
Fuse size is based on not more than 200 percent of the rated input amperage of the welding power source
(Based on Article 630, National Electrical Code).
