  • Page 1 YEARS Warranty (Power Source) 240 Volt OPERATING MANUAL KUMJR140DC KUMJR170DC Please read and understand this instruction manual carefully before the installation and operation of this equipment. © Welding Guns Of Australia PTY LTD 2012...
  • Page 2: Table Of Contents

    UNI-MIG welders are manufactured and compliant with - AS/NZ60974.1 2006 - AS60974-6:2006 guaranteeing you electrical safety and performance.
  • Page 3: Safety

    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.
  • Page 5: Working Environment

    CAUTION 1. Working Environment. 1.1 The environment in which this welding equipment is installed must be free of grinding dust, corrosive chemicals, flammable gas or materials etc, and at no more than maximum of 80% humidity. 1.2 When using the machine outdoors protect the machine from direct sun light, rain water and snow etc; the temperature of working environment should be maintained within -10°C to +40°C.

The protection class of this machine is IP21S, so avoid using it in rain. Connection of Input Cables Primary input cable is supplied with this welding equipment. Connect the primary input cable with power supply of required input voltage.
  • Page 10 MMA (Manual Metal Arc) General Description 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 ...
  • Page 11 MMA (Stick) Welding General Description 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 speci...
  • Page 12 INSTALLATION AND SET UP FOR DC TIG WELDING FOR ARC140DC-170DC (1) Switch on the machine, select the TIG function with the Tig/MMA selector switch. (2) Insert the power cable plug of the Tig torch into the Negative socket on the front of the machine and tighten it.
  • Page 13 LIFT ARC DC TIG OPERATION FOR ARC140DC-170DC Lift Arc ignition allows the arc to be started easily in DC Tig by simply touching the tungsten to the work piece and lifting it up to start the arc. This prevents the tungsten tip sticking to the work piece and breaking the tip from the tungsten electrode.
  • Page 14 DC TIG Welding General Description The DC power source uses what is known as DC (direct current) in which the main elec- trical component known as electrons  ow 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 With Filler Wire Technique

    TIG Welding Fusion Technique Manual TIG welding is often considered the most dif cult 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 ...
  • Page 16: Tungsten Electrodes

    Tungsten Electrodes Tungsten is a rare metallic element used for manufacturing TIG welding electrodes. The TIG process relies on tung- sten’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 al- loy of tungsten and other rare earth elements.
  • Page 17: Tungsten Preparation

    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  nishes not visible to the eye that will contrib- ute to weld inconsistency and weld defects.
