SAFETY PRECAUTIONS

Follow these precautions carefully. Improper use of any welder can result injury or death.

1. Only Connect Welder To A Power Source For Which It Was Designed. The spesification plate on the welder lists this information. When welding outdoors only use an extension cord interded for such use.

2. Only operate welder in dry locations and on coment 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 fro oil and grease and never coil around shoulders. 6. Secure work with clamps or other means ; dont’t overreach when working. 7. Never strike an arc on a compressed gas cyclinder. 8. Don’t allow the insulated portion of the electrode holder to tourch the

welding ground while current is flowing. 9. Shut off power and unplug machine when reparing or adjusting. Inspect

before every use. Only use idencial replacement parl. 10. Follow all manufacture’s rules on operating switches and making

adjustments. 11. Always wear protective clothing when welding. This includes :

a. Long sleeved shirt ( leather sleeves ), b. Protective apron without pockets c. 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 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.

I. MAIN USAGE AND THE RANGE OF USAGE ZX7-630C inverse argon arc welder produced with international advance technology is a new

variety of welding machine using IGBT. It has performance and high efficiency that the traditional

welder can not be compared with. The welding current is infinitely and independently adjustable.

All ferrous metal, copper and stainless steel material can be omnibearing welding in all position.

The welding current is stable. The welding seam is nice few spatters and low noise occurs during

welding. The welder has outstanding feature of minimum current. The minimum current can be

up to 50A. Protection measures of the welder are perfect. The welder is reliable, ligth in weight

and easy to use. It is particularly suitable for enterprise of plant and mine, build, decoration and

maintenance sectors.

IV. DESCRIPTION OF THE ERECTION a. Before welding, the operator should read the operation intruction.

b. Check the welder appearance for deformation and damage.

c. For the safety of the equipment and the person, the customer must correctly make grounding or

protection according to the power supply system using 4mm2 lead to connect the protectio grounding

of the welder.

d. Welding operation should be carried out in dry and good ventilating area. The surrounding objects

should be not less than 0,5m away from the welder.

e. Checking the welder output connector for tightness.

f. The welder can not be moved and the cover can not be opened during the power is on and welding

operation is carried out.

g. The welder should be cared, used and managed by specialized person.

h. Current of the distribution board : not less than 100A.

VI. METHOD OF THE OPERATION a. Hand welding with electrode

i. Regulating Current Knob “4” ( base current regulator ) to select right welding current select

empiric formula : I = 40D, D is dia. of the electrode.

ii. Notice positif and negatif connection during welding.

iii. Connecting input power for the welder, then switch, then switch on the power and current

indicating light “7” is on.

iv. Pay attention to rated welding current and rated duty cycle of the welder. Overload is not

allowed.

v. After the welding operation is finished, let the welder be ventilated for a few minutes and

then cut off the power switch.
