The operator shall have sufficient professional knowledge of welding, cutting and circuit, and have obtained the qualification certificate of welder. Only operate the machine after reading and fully understanding all the safety precautions and warnings in the manual and of welding operations.
- Page 5 8. Do not operate the welding/cutting machine in humid environment, otherwise it may cause electric shock or short circuit accident. 9. It is strictly forbidden to re-modify the equipment or the attached equipment related to the operation of the equipment without permission, to avoid accidents. 10.The disposal of the scrap equipment must comply with the relevant policies and regulations of the local government.
- Page 6 Use appropriate flame retardant shields or curtains to protect other persons from arc radiation and high temperature sparks. Welding slag has high temperature, and can be splashed over a long distance. During the removal of welding slag, the operator and viewers should wear additional safety goggles over safety glasses.
- Page 7 Prevention of Electric Shock Injuries A person contacting with live electrical components or machine can produce an electric shock, which will cause serious injury to the human body or death. Do not use welding/cutting machines in humid environment where movement is limited or there is a risk of falling.
- Page 8 Human exposed to the electromagnetic field may cause unknown health effects. Welders should minimize electromagnetic field damage through the following methods. Wrap the electrodes and the working cable with insulating cloth and secure them with tape if possible. Do not wrap wires and cables around arms. Do not put cables around your body.
