B. Drive rolls can injure fingers. C. Welding wire and drive parts are at welding voltage during operation – keep hands and metal objects clear. 1 Electric shock can kill. 1.1 Wear dry insulating gloves. Do not touch electrode with bare hand. Do not wear wet or damaged gloves. 1.2 Protect yourself from electric shock by insulating yourself from work and ground. 1.3 Disconnect input plug or power before working on machine. 2 Breathing welding fumes can be hazardous to your health. 2.1 Keep your head out of the fumes. 2.2 Use forced ventilation or local exhaust to remove the fumes. 2.3 Use ventilating fan to remove fumes. 3 Welding sparks can cause explosion or fire. 3.1 Keep flammables away from welding. Don’t weld near flammables. 3.2 Welding sparks can cause fires. Have a fire extinguisher nearby and have a watch person ready to use it. 3.3 Do not weld on drums or any closed containers. 4 Arc rays can burn eyes and injure skin. 4.1 Wear hat and safety glasses. Use ear protection and button shirt collar. Use welding helmet with correct shade of filter. Wear complete body protection. 5 Become trained and read the instructions before working on the machine or welding. 6 Do not remove or paint over (cover) the label. 2-1. Warning Label Definitions A B C 1 Read the Owner’s Manual. 2 Do not overtighten wire spool brake pressure. Tighten only until wire does not overspool from wire supply spool. 3 Do not overtighten drive roll pressure. Tighten only until drive roll will not slip (motor will not stall) on a stationary wire. 2-2.
