  • Page 5: Safety Precautions

    SAFETY PRECAUTIONS – READ BEFORE USING These general safety norms cover both arc welding machines and plasma cutting machines unless otherwise noted. The equipment must only be used for the purpose it was designed for. Using it in any other way could result in damage or injury and in breach of the safety rules.Only suitably trained and competent persons should use the equipment.
  • Page 6 Prevention against burns and radiation  Arc rays from the welding process produce intense, visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin.  Wear an approved welding helmet fitted with a proper shade of filter lens to protect your face and eyes when welding or watching ...
  • Page 7 Risks due to magnetic fields  The magnetic fields created by high currents may affect the operation of pacemakers or electronically controlled medical equipment.  Wearers of vital electronic equipment should consult their physician before beginning any arc welding, cutting, gouging or spot welding operations. ...
  • Page 8 EMF Information Considerations About Welding And The Effects Of Low Frequency Electric And Magnetic Fields Welding current, as it flows through welding cables, will cause electro-magnetic fields. There has been and still is some concern about such fields, However, after examining more than 500 studies spanning 17 years of research, a special blue ribbon committee of the National Research Council concluded that: "The body of evidence, in the committees judgment, has not demonstrated that exposure to power-frequency electric and magnetic fields is a human-health hazard."...

  • Page 10  When making input connections attach proper grounding conductor first - double-check connections.  Frequently inspect input power cord for damage or bare wiring replace cord immediately if damaged — bare wiring can kill.  Turn off all equipment when not in use. ...
  • Page 11 ARC RAYS can burn eyes and skin. Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. Sparks fly off from the weld.  Wear a welding helmet fitted with a proper shade of filler to protect your face and eyes when welding or watching (see Safety Standards).
  • Page 12 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. BUILDUP OF GAS can injure or kill. ...
  • Page 13 CYLINDERS can explode if damaged. Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. Since gas cylinders are normally part of the welding process, be sure to treat them carefully.  Protect compressed gas cylinders from excessive heat, mechanical shocks, slag, open flames, sparks, and arcs.
  • Page 14 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. ...

    2.0 Installation Worker and working area protection Fumes and gases produced by welding are dangerous for your health. Ventilation in workplace must be adequate to remove all harmful fumes and gases but not too strong since it could remove the shielding gas flowing over work piece.

  • Page 22: Output Connections

    Mains supply – 250 MTS Only The INPUT primary cable is supplied with machine. Connect the machine to mains according to your state legislation of where machine is being used. Connection can be effected through plug or direct wiring. Supply system should be protected at all times by the fuse stated in technical data section.
