- Page 2 SAFETY RULES 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 3 metals, consumable, coatings, cleaners, and de-greasers. Do not weld in locations near any de-greasing, cleaning, or spraying operations. Be aware that heat and rays of the arc can react with vapours to form highly toxic and irritating gases. ■ Do not weld on coated metals, unless the coating is removed from the weld area, the area is well ventilated, and while wearing an air-supplied respirator.
- Page 4 Precautions against fire and explosion ■ Avoid causing fires due to sparks and hot waste or molten metal ■ Ensure that appropriate fire safety devices are available near the cutting / welding area. ■ Remove all flammable and combustible materials from the cutting / welding zone and surrounding areas Do not cut/weld fuel and lubricant containers, even if empty.
- Page 5 Materials and their disposal ■ The equipment is manufactured with materials, which do not contain any toxic or poisonous materials dangerous to the operator. ■ When the equipment is scrapped, it should be dismantled separating components according to the type of materials. ■...

- Page 8 parameters when welding all DC weldable materials to produce high quality Tig welds. Our unique Torch Remote Control Interface provides remote amperage control from the torch in both static and live welding modes. The DC MMA welding function delivers a smooth and stable arc allowing easy welding with electrodes obtaining high quality welds including cast Iron, stainless and low hydrogen.

Single phases work frequency AC 220V (50 Hz) is rectified into DC (about 312V), then is converted to medium frequency AC (about 40KHz) by inverter device (IGBT), after reducing voltage by medium transformer (the main transformer) and rectifying by medium frequency rectifier (fast recovery diode), and is outputted by...
