General safety rules

The following rules must be followed or accidents may happen;

The design & construction of power supplies, the selection of installation site, and the use of high pressure 
air, etc., must abide by the relevant criteria and regulations;

Non-welding personnel should not enter the workplaces;

Installation, overhaul, maintenance, and operation must be carried out by professionals;

Other than welding, the welder should not be used for such purposes as charge, heating, etc.;

On uneven ground, make sure to keep the welder from tipping over.       

Avoid electric shock or burn

Keep the earth ground clamp connected to your work piece all the time. Never contact live components of 
the welding circuit, electrodes/torches or wires with bare hands or skin;

Connect the welder to the ground with copper wire specified section by a professional electrician.

Connect the welder to power supply by copper wire specified by a professional electrician, and make sure  
the insulation sheathing is intact;

The operator should wear dry welding gloves at work, and always keep the working piece insulated from  

him, especially at damp or small places;

Shut off the input power supply when the machine is not in use.

Avoid breathing welding smog

 

Smog generated at welding and cutting is harmful to health. To avoid gas poisoning and suffocation, keep 
the working area well ventilated.

Avoid hazards to eyes and skin by welding arc, spatter and slag

Wear approved anti-radiation glasses at work as welding arc may cause eye inflammation, and splash and 
sparks may harm eyes;

Wear welding gloves, helmet, working clothes, foot protection cover, etc. to protect the skin from such 

hazards as arc light, splash and sparks.

Prevent accidents, such as fire, explosion, outburst, etc.

Remove any flammable materials from the work area as welding splash and sparks may cause a fire;
