TS1-CTHA,L1,CTH1,CTH3,
Used to properly jumper for input voltages to the control
CTH2,CTH4/L2
transformer. L1 is internally connected to control fuse F1.
For 208/240 VAC operation - jumper CTH1 to CTH3 and CTH2 to
CTH4/L2.
For 480 VAC operation - jumper CTH3 to CTH2 only.
Used also for connections to external SCR or IGNITRON
CONTACTORS. When required connect wire (minimum 18
AWG)L1 to L1 side of external contactor.
TS1-CTH4/L2
L2 is used to provide control power. Connect wire (minimum 18
AWG) from one side of line common to the L2 welding transformer
lead. On controls furnished with integrally installed isolation switch
or circuit breaker, L2 is factory installed.
