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.

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.

7 PRODUCT DESCRIPTION

This product is sold subject to the understanding that if any defect in manufacture or material shall appear within 24 months from date of consumer sale, the supplier will arrange for such defect to be rectified without charge (except for any damage due to misuse).
