2.2 Arc Welding Hazards Welding can be dangerous to you and other persons in the work area. Read and understand this instruction manual before using your AWT welding machine. Injury or death can occur if safe welding practices are not followed.The symbols shown below are used throughout this manual to call attention to and identify possible hazards. - Page 5 Fumes And Gases Can Be Hazardous Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health. Keep your head out of the fumes. Do not breathe the fumes. Work in a confined space only if it is well ventilated, or while wearing an air-sup- plied respirator.

Turn off the power supply switch before any electric connection operation. The housing protection grade of this machine is IP21S, so do not use it in rain. - Page 11 1.Ensure that the power switch is “OFF". 2) A primary power supply cable is available for this welding machine. Connect the primary power supply cable to the corresponding voltage class based on rated input power of the welder. Incor- rect connections should be avoided. 3) The primary cable should be tightly connected to the corresponding power binding post or socket to avoid oxidization.
