SECTION 4 − MAKING WELD OUTPUT CONNECTIONS
4-1. Work And Electrode Cable Connections For Single DC or AC Arcs
! Turn Off welding power
source and disconnect input
power before opening access
door.
! High weld output current haz-
ard! Remove all metal jewelry,
such as rings and watches,
and be careful with tools near
output terminals. High current
can cause severe burns from
hot metal if touched to output
terminals and unit is On. AL-
WAYS turn Off welding power
sources and disconnect input
power BEFORE making weld
output connections.
! ELECTRIC SHOCK can kill.
Do not touch live electrical parts.
Turn off welding power sources and
disconnect input power before mak-
ing any weld output connections.
See ANSI Z49.1 and OSHA Title 29,
Chapter XVII, Part 1910, Subpart Q
(addresses at beginning of manual).
Do not handle or come in contact with
two live electrodes at the same time.
! Undersized weld cables can
cause fire.
Work cable or electrode cable must
be able to carry the weld output of the
individual welding power source (see
Section 3-8).
Do not exceed duty cycle of welding
power sources.
! If there are any questions re-
garding this procedure, con-
tact the factory before con-
necting units.
For DC electrode positive:
Connect the proper size and number
of weld output cables (see Section
3-8) to one of the welding power
source electrode terminals.
Connect the proper size and number
of ground cables to one of the welding
power source work terminals.
For DC electrode negative:
Connect the proper size and number
of weld output cables (see Section
3-8) to one of the welding power
source work terminals.
Connect the proper size and number
of ground cables to one of the welding
power source electrode terminals.
For AC output:
Connect the proper size and number
of weld output cables (see Section
3-8) to one of the welding power
source electrode terminals.
Connect the proper size and number
of ground cables to one of the welding
power source work terminals.
