2.4 CONNECTION AND PREPARATION OF EQUIPMENT
FOR STICK WELDING.
TURN OFF WELDER BEFORE MAKING CONNECTIONS.
Connect all welding accessories securely to prevent power
loss. Carefully follow safety regulations described in SAFE-
TY RULES.
1. Fit the selected electrode to the electrode clamp.
2. Connect the earth lead connector to the negative (-) quick-
connection terminal (Ref. 6 - Picture 1 Page 4.) and the earth
clamp of the workpiece near the welding zone.
3. Connect the electrode clamp connector to the positive (+)
quick-connection terminal (Ref. 5 - Picture 1 Page 4.) .
CAUTION: MAKE THE ABOVE CONNECTION FOR DIRECT
POLARITY WELDING; FOR INVERSE POLARITY, INVERT
THE CONNECTION: EARTH LEAD CONNECTOR TO THE
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.
2.5 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 reg-
ulations.
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. - 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

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 yellow LED (Ref. 3 - Picture 1 Page 4.) on
the front panel indicates a fault which prevents the equipment
from functioning.
The yellow LED indicates two fault types:
1. overheating caused by an excessively intense duty cycle. In
this case, stop welding and leave the power source switched
on until the LED switches off.
2. power supply too high/too low.
In this case, wait till the LED switches off, indicating normali-
sation of the supply voltage and then resume welding.

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. Replace damaged gas hose.
4. Repair or replace cracked cables and cords.
Every six (6) months, perform the operation below:
Blow out the inside of the unit. Increase frequency of cleaning
when operating in dirty or dusty conditions.
