 OWNER’S MANUAL

SAFETY

Welding and cutting is dangerous to the operator, people in or 
near the working area, and the surrounding, if the machine is not 
correctly operated. Therefore, the performance of welding/cutting 
must only be under the strict and comprehensive observance of 
all relevant safety regulations.  Please read and understand this 
instruction manual carefully before the installation and operation.

The switching of function modes is possibly damaging to the
machine, while the welding operation is performed.

Do disconnect the electrode-holder cable with the machine,
before the performance of welding.

A safety switch is necessary to prevent the machine from
electric-leakage.

Welding tools should be of high quality.

Operators should be qualified.

Electric shock: It could be fatal!

Connect the earth cable according to standard regulation.

Avoid all contact with live electrical parts of the welding
circuit, electrodes and wires with  bare hands. It is necessary
for the operator to wear dry welding gloves while he
performs the welding task.

The operator should keep the working piece insulating from
himself/herself.

Smoke and gas generated while welding or cutting: harmful to 
people’s health.

Avoid breathing the smoke and gas generated while welding
or cutting.

Keep the working area well ventilated.

Arc rays: harmful to people’s eyes and skin.

Wear welding helmet, anti-radiation glass and work clothes
while the welding operation is performed.

Measures also should be taken to protect people in or near
the working area.

Fire hazard

The welding splash may cause fire, thus remove flammable
material away from the working place.

Have a fire extinguisher nearby, and have a trained person
ready to use it.

Noise: possibly harmful to peoples’ hearing.

Noise is generated while welding/cutting, wear approved ear
protection if noise level is high

Machine fault:

Consult this instruction manual.

Contact your local dealer or supplier for further advice.
