Causes of fire and explosion are: combustibles reached by the

of compressed gases and cylinders; and short circuits.
BE AWARE THAT flying sparks or falling slag can pass
through cracks, along pipes, through windows or doors, and
through wall or floor openings, Out of sight of the goggled

Shock Prevention
Exposed hot conductors or other bare metal in the welding
circuit, or in ungrounded, electrically-HOT equipment can
fatally shock a person whose body becomes a conductor. DO
NOT STAND, SIT, LIE, LEAN ON, OR TOUCH a wet sur
face when welding, without suitable protection.
Clothing
To protect
Wear long-sleeve clothing (particularly for gas-shielded arc) in
addition to gloves, hat, and shoes (1-2A). As necessary, use
additional protective clothing such as leather jacket or
sleeves, flame-proof apron, and fire-resistant leggings. Avoid
outergarments of untreated cotton.
against shock:
Keep body and clothing dry. Never work in damp area with
out adequate insulation against electrical shock. Stay on a
dry duckboard, or rubber mat when dampness or sweat can
not be avoided. Sweat, sea water, or moisture between body

The input voltage jumper links provided on the primary ter
minal board permit the welding power source to be operated
from various line voltages. The various voltages from which
this unit may be operated are stated on the nameplate and on
.
the input voltage label. The input voltage jumper links are
positioned for the highest of the voltages stated on the
nameplate. If the welding power source is to be operated
from a line voltage which is lower than the highest voltage for
which the unit was designed, the jumper links will have to be
moved to the proper positions before operating the unit.
Figure 3-3 shows the various positions of the jumper links on
the standard welding power source. If the input voltages on
the nameplate differ from those shown in Figure 3-3, the
input voltage jumper links must be positioned as shown on
the input voltage label.
NOTE
If only one jumper link is required on each of the
grouped terminals, it is recommended that the unused
jumper links be placed across the terminals which are
to be used. This will prevent losing the jumper links
which are not required for this connection.

OVERLOAD PROTECTION
Thermostat TP1, located in the main transformer, is wired
into the contactor W coil circuit. Should overheating occur,
TP1 would open causing the contactor to drop out thereby
suspending all operations. If TP1 opens, allow the unit to
cool before resuming operations.
Circuit breaker CB protects the welding power source from
excessive secondary current draw. Current transformer CT1
and CT2, located in the secondary of the main transformer,
sense the secondary current draw. Should overloading occur,
CB would open causing the contactor to drop Out thereby
suspending all operations.

To place the welding power source in a ready-to-weld status
should this circuit breaker trip, the circuit breaker should be
manually reset. Should the circuit breaker continue to trip
after each reset, an internal problem in the circuitry is most
probably present. Do not attempt any further welding until
the trouble has been remedied.

DUTY CYCLE
The duty cycle of a welding power source is the percentage
of a ten minute period that a welding power source can safely
be operated at a given output. This welding power source is
rated at 100 percent duty cycle. This means that the welding
power source can be safely operated at rated load contin
uously. Figure 4-2 enables the operator to determine the safe
output of the welding power source at various duty cycles.
