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 CONNECTION AND PREPARATION OF EQUIPMENT
FOR GAS TUNGSTEN ARC WELDING (TIG)
• TURN OFF WELDER BEFORE MAKING CONNECTIONS.
Connect welding accessories securely to avoid power loss or
leakage of dangerous gases. Carefully follow the safety regula-
tions.
1. Fit the required electrode and nozzle to the electrode holder
(check the protrusion and state of the electrode tip).
2. Connect the earth lead connector to the positive (+) quick-
connect terminal Ref. 5 - Picture 1 Page 4.) and the earth
clamp to the workpiece near the welding zone.
3. Connect the torch lead connector to quick-connection nega-
tive (-) terminal Ref. 6 - Picture 1 Page 4.) .
4. Connect the torch gas hose to the gas cylinder outlet.
5. Press the illuminated switch to turn on the power source Ref.
1 - Picture 1 Page 4.) .
6. Check that there are no gas leaks.
7. Adjust welding current with ampere selector (Ref. 2 - Picture
1 Page 4.) .
CHECK GAS DELIVERY; TURN GAS CYLINDER KNOB TO
REGULATE FLOW .
NB: The electric welding arc is struck by lightly touching the work-
piece with the electrode (Scratch start).
CAUTION: WHEN WORKING OUTDOORS OR IN WINDY CON-
DITIONS PROTECT THE FLOW OF SHIELDING GAS OR IT
MAY BE DISPERSED WITH RESULTING LACK OF PROTEC-
TION FOR THE WELD.
2.5 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.
2.6 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.

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.
