13 Remote Control Switch S4
Selects Panel or remote amperage
control.
14 Circuit Breakers CB1, CB2,
CB5, And CB7
Protect 50/60 Hz auxiliary power
receptacles RC1, RC2, and RC3
from overload.
15 50/60 Hz Auxiliary Power Re-
ceptacles RC1, RC2, And
RC3
Provide connection points and
power for auxiliary equipment.
16 Circuit Breaker CB3
Protects 100 Hz auxiliary power re-
ceptacle RC4 from overload.
17 100 Hz Auxiliary Power Re-
ceptacle RC4
Provides connection point and
power for auxiliary equipment
while welding.
18 Fine Amperage Control R1
Adjusts amperage within range se-
lected by Ampere Ranges switch
S5.
19 Ampere Ranges Switch S5
Selects coarse range of weld out-
put from weld stator.
20 Reactor AC-Z
Tapped reactor limits weld output
and provides coarse ranges.
