Warning: Please read the follow safety warnings before operation.
Protective clothing - Please wear the appropriate protective clothing when welding:
1.
The welding helmet, face shield and protective goggles must be worn when in the working
area at any time.
2.
The appropriate face shied with filter and skin face shall be used to protect eyes, face, neck, and ears

body.
5.
A nonflammable partition and door curtain shall be used to protect other workers from the electric ray
and sparking.
6.
Protective goggles must be worn when cleaning welding spatter.
Fire and explosion -The heat of frame and arc can cause fire.
1.
Keep the flammable materials including wood, cloth, liquid fuel and gas fuel etc away from
the welding working area.
2.
All the walls and floor in the working area should be untracked to avoid smoldering and fire.
3.
Ensure that all the working pieces are cleared before doing welding, and do not do weld on the sealed
container to avoid burst.
4.
Fire-fighting equipment should be positioned near the welding working area.
5. Do not use the equipments overloading.
6.
The fire monitor should be used after welding.
Electric shock - Please do not use the welding source in the wet or wet areas to
avoid any injury or death.
1.
Ensure the source underpan and earthing system of input source is connected.
2.
Ensure the working pieces and good electric is connected.
3.
Ensure the working cable and working piece is connected.
4.
Always change the damaged or abrasion cable in time.
5.
Keep dry, including cloth, working area, wire, welding torch, soldering turret and power supply.
6.
Keep the body insulated from the work piece and ground.

9.
The power should be turned “OFF” before taking off protective gloves.
Electromagnetic field- It can bring dangerous.
1.
Any workers with a heart pacemaker must consult with their doctor before doing welding; the
electromagnetic field may disturb the normal work of a pacemaker.
2.
The worker shall take the following measures to down times and exposing themself to the
electromagnetic field:
(1) Put the electrode cause and work cable together, and also the tape can be used if possible.
(2) Do not wind the welding torch cable and work cable round yourself.
(3) Keep the welding torch cable and work cable to one side of yourself.
(4) Connect the work cable to the work piece, and make it to the welding area as soon as possible.
(5) Keep away from welding source and cable as much as possible.
Fog and gas -The welding fog and gas can make the worker uncomfortable or ill,
especially in the limited/poorly ventilated spaces.
1.
The aerator natural or mechanical shall be prepared in the working area. Do not do
welding on the following metals (galvanized, stainless steel, copper, zinc, read, beryllium or calcium),
and also do not breathe the welding fog and gas in.
2.
Does not weld near the degreasing or spraying operation to avoid the poisonous gas phosgene or other
imitates gas.
3.
If you feel irritation to the eyes, nose, etc, stop welding at once.
Equipment maintenance -The wrong or inappropriate equipment
maintenance can cause injury or death.
1.
Only licensed people should do assembly, maintenance and similar operation.

(1) After receiving the equipment, you should check if the equipment has been damaged during delivery. If
damaged, you should notify the courier, if parts are missing, please notify customer services at once.
(2) Take the spare parts out from packing box, remove the packing material, and check for any cast in
packing box.
(3) Check every airway in the shell, and make sure packing box cannot block air circulating.
(4) Choose roomy ground to place spare parts in order to install conveniently.

Operation
Do not operate the machine when the shell has been opened, improper cooling can damage the
parts, make sure the sideboard have been closed. When welding, you must wear helmet, gloves
and other guards.

3.1.1 ON/OFF switch
The switch on the “OFF” position means power has been closed, when the switch is in ”ON” position it
means the supply power for the main transformer and control circuit are connected.
3.1.2 Overload light
If welding with large current for a long time and exceed the duty cycle, the overload lamp will light (yellow),
the machine will stop working until cooling to the stated temperature. When the overload lamp lights you
must turn the switch to “OFF” position and wait about 15 minutes, then you can continue.

3.3 Operation
Step 1: Use ground clamp to connect the grounding cable and work piece or connect the metal carriages (as
work table) make sure the clamp has been contacted fully with work piece and clear any rust and paint.
Step 2: Check the position of power switch, position must be on “OFF”, then insert the inlet wire to the socket
(voltage is 230VAC, rated current of socket ≥15A).
Step 3: Discharge the nozzle cover and contact tip at the head of welding torch, pull the soft pipe.
Step 4: The welding tongs that clamp the rod can’t be contacted with any grounding objects. Turn the
conversion switch to voltage position (the same with input voltage) and the power lamp (green) will light.
Step 5: Press (and hold) the torch button until distance between wire and welding torch is 30mm, loosen torch
button.
Step 6: Close the power; fix the contact tip and nozzle cover onto the welding torch. (Wire must run through the
contact tip and nozzle cover.)
Step 7: Open the power, press the switch repeatedly, adjust the speed by turning the adjusting wire feed speed
knob.
Step 8: Orient yourself on the area to be welded, and then place the face shield over your eyes.
Step 9: Press (and hold) the torch button and stroke the area to be welded with the electrode wire
to ignite the arc.
Step 10: Once the arc is ignited, tilt the electrode wire forward at an angle of approximately 35o. (diagram 3-3)

Step 12: When the weld is complete, lift the electrode wire clearly away from any grounded object. Set the face
shield down and turn the power switch to the “OFF” position.
Step 13: Unplug the power cord from the electrical outlet.
If welding with large current for a long time and exceed the duty cycle, the overload lamp
will light (yellow), the machine will stop working until cooled. When the overload lamp
lights you must turn the switch to “OFF” position and wait about 15 minutes, then you can
continue.

Maintenance
4.1 Summary
If the equipment can’t work normally, you should stop working at once and check for
faults. You must use a trained professional for maintenance; those without appropriate
training must not check, clear or repair equipment. When repairing use appropriate spare
parts.
Before any maintenance, make sure the main switch has been cut or remove the fuse.
4.2 Cleanness
Take the shell and sideboard trim, and use clean and dry low-pressure air to blow dust and dirt from air alleyway
and inner parts. Clear the dirt, dregs and grime from the head of welding tongs trim.
In order to allow enough circulating and supply proper cooling, it’s necessary to keep the alleyway clean.
After cleaning by low-pressure, check if any hardware has become flexible, if flexible, you must firm them.
Check if insulation of cable has been frayed, if the cable has been frayed, you must replace it.
If you replace the cable improperly, the bare cable may contact the grounding objects. The
arc can hurt your eyes or cause fire. If the body comes into contact with the cable linker or
lead; you may be burned/injured.
4.3 Check and Maintenance
Keep the power dry, remove grease and make sure the power can’t be damaged by flaming metal and spark.
4.3.1 Transformer
Transformer needn’t any maintenance except to clear the dust and dirt trim. Use low-pressure air to let it clean
and dry.
4.3.2 Replacing the wire reel
When the wire on the feed reel is used up, you will need to replace as in section 2.3.2.
4.3.3 Cable
Place cable in a clean and dry place.
