QUICK-CONNECTION POSITIVE (+) TERMINAL AND THE
ELECTRODE HOLDER CLAMP CONNECTOR TO THE NEGA-
TIVE (-) TERMINAL.
4. Adjust welding current with ampere selector (Ref. 2 - Picture
1 Page 4.) .
5. Press the illuminated switch to turn on the power source Ref.
1 - Picture 1 Page 4.) .
N.B. Serious damage to the equipment may result if the power
source is switched off during welding operations.
The power source is fitted with an anti-sticking device that dis-
ables power if output short circuiting occurs or if the electrode
sticks, allowing it to be easily detached from the workpiece.
This device enters into operation when power is supplied to the
generator, even during the initial checking period, therefore any
load input or short circuit that occurs during this phase is treated
as a fault and will cause the output power to be disabled.
2.4 REDUCTION OF EMF IN THE WORKPLACE
ELECTROMAGNETIC FIELD CAN AFFECT PACEMAKER OP-
ERATION.
High current flowing through the welding cables during the weld-
ing operation causes a generation of electromagnetic fields. To
reduce the intensity of these fileds in the workplace (if required),
use the following procedures:
1. Keep the cables arranged close together by twisting or taping
them.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep welding power source and cables as far away from op-
erator as practical.
5. Connect earth clamp to workpiece as close to the welded
area as possible.
2.5 LIMITATIONS OF USE
This equipment is designed for use under standard operational
and environment conditions. To ensure its full operational capabil-
ity; to avoid the danger and possibility of equipment's damage
please always follow these recommendations:
1. Do not use the equipment in areas with extremaly low or high
ambient temperature.
2. Do not use the equipment in areas with presence of danger-
ous, flamable and/or explosive gases.
3. Avoid the contact of equipment with water; do not use the
equipment outdoors when it is rainig and/or snowing.
4. Never use the welding power source for pipe thawing; this
equipment is designed solely for welding.

1. Connect the earth lead to the work piece to the negative ter-
minal (-) (Ref. 6 - Picture 1 Page 4.)
2. Connect the torch lead to the positive terminal (+) (Ref. 5 -
Picture 1 Page 4.).
ENSURE THAT THESE CONNECTIONS ARE WELL TIGHT-
ENED TO AVOID POWER LOSS AND OVERHEATING.
3. Use control knob (Ref. 2 - Picture 1 Page 4.) to regulate
welding current.
4. Illuminated switch (Ref. 1 - Picture 1 Page 4.) must be ON
(lamp light) before welding operations can be started.
5. Illumination of the transparent LED (Ref. 3 - Picture 1 Page

MAINTENANCE

DISCONNECT POWER BEFORE MAINTENANCE. SERVICE
MORE OFTEN DURING SEVERE CONDITIONS.
Every three (3) months, perform the operations below:
1. Replace unreadable labels.
2. Clean and tighten weld teminals.
3. Repair or replace cracked cables and cords.
Every six (6) months, perform the operation below:
