INSTRUCTIONS
Suitable for
110~240V

SAFETY PRECAUTIONS
Follow these precautions carefully. Improper use of any welder can result in injury or death.
1. ONLY CONNECT MACHINE TO A POWER SOURCE FOR WHICH IT WAS DESIGNED.
THE SPECIFICATION PLATE ON THE MACHINE LISTS THIS INFORMATION. WHEN
WELDING OUTDOORS ONLY USE AN EXTENSION CORD INTENDED FOR SUCH USE.
2. ONLY OPERATE MACHINE IN DRY LOCATIONS AND ON CEMENT OR MASONRY FLOOR.
KEEP AREA CLEAN AND UNCLUTTERED.
3. KEEP ALL COMBUSTIBLES AWAY FROM WORK SITE.
4. DO NOT WEAR CLOTHING THAT HAS BEEN CONTAMINATED WITH GREASE OR OIL.
5. KEEP CABLES DRY AND FREE FROM OIL AND GREASE AND NEVER COIL AROUND
SHOULDERS.
6. SECURE WORK WITH CLAMPS OR OTHER MEANS – DON’T OVER-REACH WHEN
WORKING.
7. NEVER STRIKE AN ARC OVER A COMPRESSED GAS CYLINDER.
8. DON’T ALLOW THE INSULATED PORTION OF THE ELECTRODE HOLDER TO TOUCH
THE GROUND WHILE CURRENT IS FLOWING.
9. SHUT OFF POWER AND UNPLUG MACHINE WHEN REPAIRING OR ADJUSTING.
INSPECT BEFORE EVERY USE. ONLY USE IDENTICAL REPLACEMENT PARTS.
10. FOLLOW ALL MANUFACTURER’S RULES ON OPERATING SWITCHES AND MAKING
ADJUSTMENTS.
11. ALWAYS WEAR PROTECTIVE CLOTHING WHEN WELDING. THIS INCLUDES: LONG
SLEEVED SHIRT (LEATHER SLEEVES), PROTECTIVE APRON WITHOUT POCKETS, LONG
PROTECTIVE TROUSERS, BOOTS AND GLOVES WHEN HANDLING HOT MATERIALS.
12. ALWAYS WEAR A WELDER’S HELMET WITH PROTECTIVE EYE PIECE WHEN WELDING.
WEAR A PROTECTIVE CAP UNDERNEATH THE HELMET.
13. WHEN WELDING OVERHEAD, BEWARE OF HOT METAL DROPPINGS. ALWAYS PROTECT
THE HEAD, HAND, FEET AND BODY.
14. KEEP A FIRE EXTINGUISHER CLOSE BY AT ALL TIMES.
15. DO NOT EXCEED THE DUTY CYCLE OF THE MACHINE. THE RATED CYCLE OF A
WELDING MACHINE IS THE PERCENTAGE OF A TEN MINUTE PERIOD THAT THE
MACHINE CAN OPERATE SAFELY AT A GIVEN OUTPUT SETTING.
16. KEEP ALL CHILDREN AWAY FROM WORK AREA. WHEN STORING EQUIPMENT, MAKE
SURE IT IS OUT OF REACH OF CHILDREN.
17. GUARD AGAINST ELECTRIC SHOCK. DO NOT WORK WHEN TIRED. DO NOT LET BODY
COME IN CONTACT WITH GROUNDED SURFACES.

4 PRODUCT DESCRIPTION
• Before welding, the operator should read the operating instructions.
•Check the machine appearance for deformation and damage.
•For the safety of the equipment the operator must make an appropriate earth according
to the power supply system.
•The welding operation should be carried out in a dry and well ventilated area.
•Check the machine output connection.
•The machine should not be moved or the cover opened when the power is on and
during the welding operation.
•The machine should be maintained, operated and managed by a qualified person.
•Confirm the power source is single phase and 110V or 240V ± 10% and distribution
board current is 5KVA.

6 MACHINE OPERATION
6.1 Connect the machine correctly according the diagram. Switch on the air compressor
until it reaches its rated pressure. It will turn off automatically. Adjust the air pressure
reducing valve to the required value (0.2-0.4MPa)
6.2 Connect the power to the machine and the power indicator light will illuminate and
the cooling fan will start. Select the AIR TESTING setting on the function switch and air
will flow through the torch. Select CUTTING on the function switch and air will flow
through the torch again.
6.3 Select a suitable current with the current control knob for the thickness of the material
and one that is suitable for the consumables fitted to the torch.
6.4 CUTTING: Hold the cutting torch on the workpiece at approximately a 15 degree angle
and press the torch switch. The air will flow first and then the arc will ignite. Start to
move the torch after the material has been pierced maintaining a uniform pace of travel
and distance across the material.
