SAFETY PRECAUTIONS
Follow these precautions carefully. Improper use of any welder can
result in injury or death.
1. ONLY CONNECT WELDER TO A POWER SOURCE FOR WHICH IT WAS DESIGNED.
The specification plate on the welder lists this information. When welding outdoors only use an
extension cord intended for such use.
2. ONLY OPERATE WELDER IN DRY LOCATIONS and on cement or masonry floor. Keep area
clean and un-cluttered.
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 overreach when working.
7. NEVER STRIKE AN ARC ON A COMPRESSED GAS CYLINDER
8. DON'T ALLOW THE INSULATED PORTION OF THE ELECTRODE HOLDER TO TOUCH
THE WELDING GROUND WHILE CURRENT IS FLOWING.
9. SHUT OFF POWER AND UNPLUG MACHINE WHEN REPAIRING OR ADJUSTING. Inspect
before every use. Only use identical replacement parl.
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 pants and boots. When handing hot
materials, wear asbestos gloves.
12. ALWAYS WEAR A WELDER'S HELMET WITH PROTECTIVE EYE PIECE when welding.
Arcs may cause blindness. 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.

1.BRIEF INTRODUCTION
CUT-40M INVERTER AIR PLASMA CUTTING MACHINES are all our own high-new
technical products with special purpose power parts and up-to-date inverter control IC. The
machines hold a safe lead of traditional products and other inverter cutting machines by their
cutting thickness ,seam smooth degree, arc generation and cutting current ,and the machine is
compressed air and the cost of cutting is very low. All stainless steel,copper,Aluminum,titanium,
cast steel,alloy steel,carbon steel and compound metal material can be cutting in all position.
2. OPERATING CONDITION AND WORK SURROUNDING
1.Operating condition: Reliable grounding protection
±

2. For the safety of the equipment and the persons, the customer must correctly make grounding
or protection according to the power supply system:using 4 mm2lead to connect the protection
grounding of the cutting machine.
3. Cutting operating should be carried out in dry and good ventilating area. The surrounding
objects should be not less than 0.5m away from the cutting machine.
4 . Before cutting , the operator should read the operation instructions carefully and use the
machine correctly.

6. METHOD OF THE OPERATION
1. Connect the machine correctly according the sketch. And switch on the air compressor until to
its rated pressure. It will be turned off automatically to adjust the air pressure-reduced valve to the
proper value.(0.2-0.35MPa generally)
2. Join the power switch of the cutting machine. The power indication lamp lights.The cooling
fan begins working. Put the function switch in the position of "air testing" .Then the air spouts
from the cutting torch. Let the function switch in the position of " cutting", and press the torch
switch. The air spouts from the torch also.
3. Selecting suitable cutting current and air pressure according to the thickness and material of
the workpiece and the cutting speed.The selecting standard for the spray nozzle of the torch:
The spray nozzle not change color while cutting.
4. CUTTING: Hold the cutting torch in the beginning position, and let the nozzle towards the
workpiece with 15 angle of inclination. The nozzle touches the workpiece, and press the torch
switch, Now flow the air first and high frequency arc generated.The high frequency can be cut
off automatically after the arc generation ,Begin to move the cutting torch after the workpiece is
pierced through. Loosen the switch after finish cutting.
7.This product is subject to the understanding that if any defect in
manufacture or material shall appear within 12 months from date
of consumer sale , the manufacturer will arrange for such defect to be
rectified without charge on the sales invoice and warranty
card. (except for any personal trouble)
