Do not touch live parts with naked skin, wet gloves or wet clothes.
Be sure you are insulated from ground and workpiece.
Cover the cover plate of the machine before power on to avoid an
electric shock.
Confirm the safety of your working position.
Beware of fire hazard!
Please install the machine on non-combustible materials to avoid
a fire.
Make ensure there are no inflammables near the welding position
to avoid a fire.
Beware of explosion !
Do not install the machine in an environment with explosive gas
to avoid an explosion.
Replacing the components can be dangerous.
Only professionals can replace the components of the machine.
Make sure the connecting wires inside the machine are correctly connected after replacing
the PCBs, and then the machine can be run. Otherwise, there is a risk of damage to
property.
Make sure there are no foreign bodies such as wire leads, screws, gaskets and metal bars
falling into the machine inside when replacing the components.

Precautions for operation
Smoke-may be harmful to your health!
Keep your head away from the smoke to avoid inhalation of waste gas
in welding.
Keep the working environment well ventilated with exhaust or ventilation
equipment when welding.
Arc radiation-may hurt your eyes and burn your skin!
Use proper welding mask and wear protective clothing to protect your
eyes and body.
Use proper mask or curtain to protect onlooker from being injured.
Magnetic field can make cardiac pacemaker a bit wonky!
Stay away from the welding source to reduce the affect of magnetic filed.
Improper use and operation may result in a fire or an explosion!
Welding spark may result in a fire, so please make ensure there are no
inflammables near the welding position, and pay attention to fire safety.
Ensure there is fire extinguisher nearby, and make sure someone has
been trained to operate the fire extinguisher.
Do not weld closed container.
Do not use this machine for pipe thawing.
Hot workpiece can cause severe scald!
Do not touch hot workpiece with bare hands.
Cool the welding torch for a while after continuously working.
Excessive noise does great harm to people’s hearing!
Wear ear covers or other hearing protectors when welding.
Give warning to onlooker that noise may be potentially hazardous to
hearing.
Moving parts may injure your body!
Please keep away from moving parts (like fan).
Each door, panel, cover, baffle plate, and protective device the like
should be closed and located correctly.
Seek professional support when trouble strikes!
When trouble strikes in installation and operation, please inspect
according to related contents in this manual.
If you still cannot understand fully, or you still cannot solve the problem,
Precautions for discard
Pay attention to the following when discarding the welding machine:
Burning the plastic parts such as the front panel may produce poisonous gas.
Dispose it as industrial waste.
Burning the electrolytic capacitors in the main circuit or on the PCBs may cause an explosion.
People with cardiac pacemaker should consult the doctor before carrying
out welding.
please contact the dealer or the service center of JASIC to obtain
professional support.

2. INSTALLATION AND CONNECTION
2.1 Installation requirements
In order to ensure personal safety and avoid electric shock, please ground the machine reliably
by connecting the ground wire (yellow-green wire) of the machine to the grounding device in
the switching box.
Insert the plugs with the cable of the electrode holder and the cable of the earth clamp respectively
into the quick sockets on the front panel of the machine, and tighten them to clockwise.
Operator can choose DCEN connection according to workpiece and electrode application
requirement. Generally, DCEP connection is recommended for basic electrode, while there is
no special requirement for acid electrode.
DCEN: Connect the electrode holder to “-” output
terminal, and the workpiece to “+” output terminal.
DCEP: Connect the electrode holder to “+” output
terminal, and the work clamp to “-” output terminal.
Figure 2-1: Connection of output cable
Figure 2-2: Connection of quick plug
1) Connection of input cable
A primary power supply cable is available for this welding machine. Connect the power supply
cable to the rated input power. The primary cable should be tightly connected to the correct
socket to avoid oxidization. Check whether the voltage value varies in acceptable range with a
multi-meter.
The cross section of the leads used in the switching box should meet the requirements of the
maximum input capacity of the machine.
