Xcel-Arc welders are manufactured and compliant with - AS/NZ60974.1 2006 - AS60974-6:2006 guaranteeing you electrical safety and performance. - Page 3 SAFETY Welding and cutting equipment can be dangerous to both the operator and people in or near the surrounding working area, if the equipment is not correctly operated. Equipment must only be used under the strict and comprehensive observance of all relevant safety regulations. Read and understand this instruction manual carefully before the installation and operation of this equipment.
- Page 4 Fire hazard. Welding on closed containers, such as tanks,drums, or pipes, can cause them to explode. Flying sparks from the welding arc, hot work piece, and hot equipment can cause fires and burns. Accidental contact of electrode to metal objects can cause sparks, explosion, overheating, or fire.

Most GP electrodes are Electrode connected to output socket, Earth Connected to the output socket (2) Connect the machine to the power supply and switch on using the on/off switch on the back panel.
- Page 10 MMA (Manual Metal Arc) Welding One of the most common types of arc welding is manual metal arc welding (MMA) or stick welding. An electric cur- rent is used to strike an arc between the base material and a consumable electrode rod or ‘stick’. The electrode rod is made of a material that is compatible with the base material being welded and is covered with a flux that gives off gaseous vapours that serve as a shielding gas and providing a layer of slag, both of which protect the weld area from atmospheric contamination.

Page 11: Mma (Stick) Welding Fundamentals
MMA (Stick) Welding Fundamentals Electrode Selection As a general rule, the selection of an electrode is straight forward,in that it is only a matter of selecting an electrode of similar composition to the parent metal. However, for some metals there is a choice of several electrodes, each of which has particular properties to suit specific classes of work. - Page 12 Installation & Set Up for DC TIG Welding with ARCLITE 140 / 160 (1) Switch on the machine. (2) Insert the power cable plug of the Tig torch into the Negative socket on the front of the machine and tighten it. (3 Insert the earth cable plug into the Positive socket on the front of the machine and tighten it.
- Page 13 SCRATCH ARC DC TIG Operation with ARCLITE 140 / 160 Scratch Arc ignition allows the arc to be started in DC Tig by lightly scratching the tungsten in a backward motion against the work piece, (similar to striking a match) lift the tungsten slightly from the work piece to establish and hold an arc.

Page 14: Dc Tig Welding
DC TIG Welding The DC power source uses what is known as DC (direct current) in which the main elec- trical component known as electrons flow in only one direction from the negative pole (terminal) to the positive pole (terminal). In the DC electrical circuit there is an electrical principle at work which should always be taken into account when using any DC circuit. -
Page 15: Tig Welding Fusion Technique
TIG Welding Fusion Technique Manual TIG welding is often considered the most difficult of all the welding processes. Because the welder must maintain a short arc length, great care and skill are required to prevent contact between the electrode and the workpiece. Similar to Oxygen Acety- lene torch welding, Tig welding normally requires two hands and in most instances requires the welder to manually feed a filler wire into the weld pool with one hand while manipulating the welding torch in the other. - Page 16 Tungsten Electrodes Tungsten is a rare metallic element used for manufacturing TIG welding electrodes. The TIG process relies on tungsten’s hardness and high-temperature resistance to carry the welding current to the arc. Tungsten has the highest melting point of any metal, 3,410 degrees Celsius. Tungsten electrodes are nonconsumable and come in a variety of sizes, they are made from pure tungsten or an alloy of tungsten and other rare earth elements.
- Page 17 Tungsten Preparation Always use wheels when grinding and cutting. While tungsten is a very hard material, the surface of a DIAMOND diamond wheel is harder, and this makes for smooth grinding. Grinding without diamond wheels, such as aluminium oxide wheels, can lead to jagged edges, imperfections, or poor surface finishes not visible to the eye that will contrib- ute to weld inconsistency and weld defects.
