  • Page 4: Fumes And Gases Can Be Hazardous

    roll housing, and all metal parts touching the welding wire are electrically live. Incorrectly installed or improperly grounded equipment is a hazard. ●Do not touch live electrical parts. ●Wear dry, hole-free insulating gloves and body protection. ●Insulate yourself from work and ground using dry insulating mats or covers big enough to prevent any physical contact with the work or ground.

    consumables, coatings, cleaners, and degreasers. ●Work in a confined space only if it is well ventilated, or while wearing an air-supplied respirator. Always have a trained watchperson nearby. Welding fumes and gases can displace air and lower the oxygen level causing injury or death.

  • Page 6: Flying Metal Can Injure Eyes

    ●Remove any combustibles, such as a butane lighter or matches, from your person before doing any welding. FLYING METAL can injure eyes. ●Welding, chipping, wire brushing, and grinding cause sparks and flying metal. As welds cool, they can throw off slag. ●Wear approved safety glasses with side shields even under your welding helmet.

  • Page 7: Overuse Can Cause Overheating

    ●Never drape a welding torch over a gas cylinder. ●Never allow a welding electrode to touch any cylinder. ●Never weld on a pressurized cylinder-explosion will result. ●Use only correct shielding gas cylinders, regulators, hoses,and fittings designed for the specific application; maintain them and associated parts in good condition. ●Turn face away from valve outlet when opening cylinder valve.
  • Page 8 STATIC (ESD) can damage PC boards. ●Put on grounded wrist strap BEFORE handling boards or parts. ●Use proper static-proof bags and boxes to store, move, or ship PC boards. MOVING PARTS can cause injury. ●Keep away from moving parts. ●Keep away from pinch points such as drive rolls. WELDING WIRE can cause injury.

  • Page 9: Emf Information

    ●Be sure all equipment in the welding area is electromagneticallycompatible. ●To reduce possible interference, keep weld cables as short as possible, close together, and down low, such as on the floor. ●Locate welding operation 100 meters from any sensitive electronic equipment. ●Be sure this welding machine is installed and grounded according to this manual.

  • Page 10: Section 2 - Principles Of Mig/Mag Or No Gas

    SECTION 2 – PRINCIPLES OF MIG/MAG OR NO GAS FLUX CORED WIRES WELDING Metal Inert/Active Gas-shielded arc welding ( MIG/MAG ) or Gas Metal Arc Welding ( GMAW ) methods are some processes which melt and join metals by heating them with an arc between a small diameter metal wire electrode and the workpiece.
  • Page 11 characteristic, or constant-current output characteristic. With the drooping _____________________________________________________________________ characteristic , a small change in arc voltage will produce a much smaller change in arc current, depending upon the open circuit voltage (OCV) of the welding machine. This means the wire ‘burn-off’ rate is much slower for MMA welding, or put another way, for any given change in arc length the welding current change is small.
  • Page 12 you should set a flow rate of between 12-18 ltrs/min. If Gas flow rates are too high or low,the porosity of weld bead will occur. The contact tip is another important consideration. This does get damaged easily and is essential to good electrical contact, as it transfers current to the wire.

OPERATING INSTRUCTIONS ●The welding machine should be put in the place with good ventilation. The ambient environment should not have dust, humidity and vapor. ●The machine should be kept away from the sunlight and rain.
  • Page 18 Caution: Please don’t use the gun mouth to face any part of the human body during wire feeding! Other precautions ●When the thermal protection device is working, it will shut off the output of the welding machine and the yellow indicator lamp will be on.When the thermal protection device is automatically reset, the yellow indicator lamp will be off.
