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. 2-2.

Use lifting eye to lift unit only, NOT running gear, gas cylinders, or any other accessories. Use equipment of adequate capacity to lift and support unit. If using lift forks to move unit, be sure forks are long enough to extend beyond opposite side of unit. 1 Lifting Eye 2 Lifting Forks Use lifting eye or lifting forks to move unit. If using lifting forks, extend forks beyond opposite side of unit. 3 Rating Label Use rating label to determine input power needs. 4 Line Disconnect Device Locate unit near correct input power supply. Special installation may be required where gasoline or volatile liquids are present – see NEC Article 511 or CEC Section 20. Be careful when placing or moving unit over uneven surfaces. 3-1.

Duty Cycle And Overheating Duty Cycle is the percentage of 10 minutes that the unit can weld at rated load without overheating. If unit overheats, output stops, front panel voltmeter/ammeter displays a HLP3 or HLP5 message (see Section 5-4), and cooling fans run. Wait fifteen minutes for unit to cool. Reduce amperage or duty cycle before welding. Exceeding duty cycle can damage unit and void warranty. 40% Duty Cycle At 350 Amperes (60 Hz Models Only) Overheating 0 15 A OR Minutes Reduce Duty Cycle duty1 4/95 / SB-190 276 60% Duty Cycle At 300 Amperes ssb1.1 10/91 – STThe volt-ampere curves show the minimum and maximum voltage and amperage output capabilities of the welding power source.
