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 concrete 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 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 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 pants and boots. When
handling 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.

MAIN USAGE AND THE RANGE OF USAGE

AC/DC200D Welder is a triple functional machine used as DC MMA, AC TIG, DC/PULSE TIG
Welder. All ferrous metals, copper, aluminium, titanium and stainless steel material can be welded
from all positions. The welding current is stable and the stepless is adjustable. Few spatter and low
noise occurs during welding. The welder is compact, light in weight and easy to move. It is suitable
for pressure vessel, building, shipping and petrochemical industries. It is the priority product to replace
the NSA series welding machine.

OPERATING INSTRUCTIONS

1. Before welding, the operator should read the operation instructions.

2. Check the welder appearance for any damage before operation.

3. To ensure safe operation, the welder must be grounded correctly according to your local

power supply system using a 4mm

2

lead to connect the welder to the ground.

4. Welding should only be carried out in dry and well ventilated areas. Surrounding objects should

not be less than 0.5m away from the welder.

5. Check the welder output connector for tightness.

6. The welder cannot be moved and the cover cannot be opened while the power is on and

welding operation is carried out.
