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 DESIGEND.
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 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 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.

6. Explanation of installation
6.1 MIG/MAG welding
put the switch"7" MIG/MMA SWITCH into "MIG"
★Check the products according to the packing list when open the package.
★
Grounded protection.Attached the diagram 6
The power source is 220Vac/(50~60Hz) .The yellow/green double cable is grounding
cable.Be sure to connect the yellow/green double cable into the grounding connection in the
welding locale .Another way is selecting the M8 bolt on the back on the machine and connect
the grounding as the diagram as following.
★
Install the welding gun on the front panel and screw the welding gun ,then lock the bolt.
★Connect the gas pipe with the gas bottle according to the locale conditions. Check the
air proof conditions to ensure the good airproof.

7. Operatings
★
"ON" and "OFF" indicating switch on the back panel.
★
Preset the welding voltage ,welding current(wire speed).and Arc force.Diagram 4
★
Confirm the specification of the wire feed hose
★Confirm the specification of nib base .It affects the extended length of the wire .
★Confirm the specification of nib. It affects the electric resistance.
★Confirm the wire slot of the roller is suitable for the diameter of the wire. Different
diameter of wire select different wire slot. Otherwise it affects the wire feed result.
★Confirm the pressure of the roller to avoid slipping.
If the pressure is not enough ,the wire feed is slow speed.
If the pressure is too much ,the wire will be anamorphic.
The wire feeder can not work properly.
★
Confirm the flow of the gas and air proof.
We suggest the gas flow to be "L" more than 10D(D-diameter of wire ).If the selection is
not proper,it also affects the welding quality.When using the CO2gas,please confirm if the
heating power works properly or not .
★Straight the hose of welding gun as much as possible .The bending radius can not be
less than 160mm.Otherwise it affects the wire feeder.
7.1 working process
press the switch of the gun ,the normal welding begins.Relax the switch,the arc stops.
7.2 Gas inspection
Press the switch of the gun before the wire roller is firmed,preset the gas flow through the
meter to check if it is gas proof.Otherwise ,it affects the welding result.
7.3Rip into the wire
Select the specification of the wire ,materials according to the craft requirements.Firm the
bolt and press the button on the front panel.The speed of ripping wire can be controlled by the
welding current knob.Unload the nib if necessary and load it again after the wire is out.
