Page 5: Safety
2. Safety Warning! Before starting welding, please carefully read the safety instructions, understand the hazards generated during welding, and carry out corresponding inspections and protections. Some hazards may be fatal! 2.1 Before welding work 2.1.1 Environment check The machine should work in low dust environments. Large amounts of dust may enter the machine, and if there are conductive substances in the dust, it may cause damage to the machine and even endanger personal safety. - Page 6 Please wear a mask during welding work. During welding, toxic gases or suspended particles may be generated. Although you are in a well ventilated environment and inhale only a small amount of harmful substances, long-term inhalation still poses great harm. May cause you to fall ill. 2.2.2 Noise hazards Wear ear protectors during the welding process.

Page 7: After Welding Work
2.3 After welding work 2.3.1 High temperature attention The workpiece and welding torch that have just been welded are in a high temperature state, and must not be touched directly, which will burn the skin. The welding torch or welding rod that has just been welded has a high temperature and should be disposed of properly, and placed on flammable objects or items with a low melting point, which may cause property loss and personal safety hazards. -
Page 8: Install
Install 3.1 Content Before starting welding or cutting work, the first step is to figure out which tools we need to use and how to make the correct connection. If the polarity is wrongly connected, it may easily damage welding or cutting tools (especially welding torches and cutting torches), and secondly, it may lead to poor welding and cutting effects. -
