Transarc 141VRD, 161VRD 1. INTRODUCTION 1.1 Notes, Cautions and Warnings Throughout this manual, notes, cautions, and warnings are used to highlight important information. These highlights are categorised as follows: NOTE An operation, procedure, or background information which requires additional emphasis or is helpful in efficient operation of the system. CAUTION A procedure which, if not properly followed, may cause damage to the equipment.
Transarc 141VRD, 161VRD ELECTRIC SHOCK Electric Shock can injure or kill. The welding arc process uses and produces high voltage electrical energy. This electric energy can cause severe or fatal shock to the operator or others in the workplace. ♦ Never touch any parts that are electrically “live” or “hot.” ♦ Wear dry gloves and clothing. Insulate yourself from the work piece or other parts of the welding circuit. ♦ Repair or replace all worn or damaged parts.
Transarc 141VRD, 161VRD 2. ELECTROMAGNETIC COMPATIBILITY WARNING 2 Extra precautions for Electromagnetic Compatibility may be required when this Welding Power Source is used in a domestic situation. 2.1 Installation and use - Users Responsibility The user is responsible for installing and using the welding equipment according to the manufacturer’s instructions.
Transarc 141VRD, 161VRD Shielding should be electrically continuous throughout its length. The shielding should be connected to the Welding Power Source so that good electrical contact is maintained between the conduit and the Welding Power Source enclosure. b) Maintenance of Welding Equipment The welding equipment should be routinely maintained according to the manufacturer’s recommendations.
Transarc 141VRD, 161VRD 3. GENERAL INFORMATION 3.1 Transarc 141VRD The Transarc 141VRD is a 240 volt, single phase, constant current, 140 amps at 60% duty cycle, DC stick -lift TIG power source.
Transarc 141VRD, 161VRD Note that all duty cycles are calculated for a maximum ambient temperature of 40°C as per AS1966. Duty cycles must be reduced, ie reduce the arc-on time, when the ambient temperature exceeds 40°C. 3.5 Terms Of Warranty - June 2002 1.
Transarc 141VRD, 161VRD 3.6 Warranty Schedule - June 2003 These warranty periods relate to the warranty conditions in clause 2. All warranty periods are from date of sale from the Accredited Distributor of the equipment. Notwithstanding the foregoing, in no event shall the warranty period extend more than the time stated plus one year from the date CIGWELD delivered the product to the Accredited Distributor. Unless otherwise stated the warranty period includes parts and labour.
Transarc 141VRD, 161VRD ♦ Do not stand on damp ground when welding. 4.2 Personal Protection The radiation from an electric arc during the welding process can seriously harm eyes and skin. It is essential that the following precautions be taken: ♦ Gloves should be flameproof gauntlet type to protect hands and wrists from heat burns and harmful radiations. They should be kept dry and in good repair. ♦ Protective clothing must protect the operator from burns, spatter and harmful radiation.
Transarc 141VRD, 161VRD 5.1 Resuscitation Efficient resuscitation requires training which is available from the St John’s Ambulance Association, Red Cross and other sources. 1 Don’t become a victim. Switch off power if possible. If not, remove victim from contact, using some insulating material. 2 If unconscious, place victim on their side and clear vomit and other foreign matter from mouth. Check for breathing by look, listen and feel. If not breathing, commence expired air resuscitation (E.A.R.).

Transarc 141VRD, 161VRD b) For fixed equipment, at least once every 12 months. The owners of the equipment shall keep a suitable record of the periodic tests. Note 3 A transportable power source is any equipment that is not permanently connected and fixed in the position in which it is operated. In addition to the above tests and specifically in relation to the VRD fitted to this machine, the following periodic tests should also be conducted by an accredited CIGWELD service agent.
Transarc 141VRD, 161VRD 8.4 Mains Supply Voltage Requirements The Mains supply voltage should be within ± 10% of the rated Mains supply voltage. Too low a voltage may cause the fuse or circuit breaker to rupture due to the increased primary current. Too high a supply voltage will cause the Power Source components to fail. 8.5 Minimum 240V Mains Current Circuit Requirements CAUTION 1 CIGWELD recommends that the maximum 240V extention cable length used with this equipment is 20 metres.
Transarc 141VRD, 161VRD b) Two Line Digital Display Preview Weld Current Preview Weld Current is displayed on the first top line of the display when the operator is not welding. The welding current is increased by turning the WELD CURRENT Control knob clockwise or decreased by turning it anti-clockwise. Weld Current when Welding Weld Current is displayed on the first top line of the display when the operator is welding and for 5 seconds after the arc has extinguished.

Transarc 141VRD, 161VRD 12. BASIC TIG WELDING GUIDE 12.1 Electrode Polarity Connect the TIG torch to the ‘-’ terminal and the work lead to the ‘+’ terminal for direct current straight polarity. Direct current straight polarity is the most widely used polarity for DC TIG welding. It allows limited wear of the electrode since 70% of the heat is concentrated at the work piece. 12.2 Tungsten Electrode Current Ranges Electrode Diameter (mm) DC Current (Amps) 1.0 30 – 60 1.6 60 – 115 2.4 100 – 165 3.
