Page 4: Principles Of Operation
PRINCIPLES OF OPERATION The ARC/TIG welder, as its name suggests, is designed to be used for both Metal ARC, AND TIG welding. To accomplish this, two sets of welding leads are required, one for each method employed. ARC WELDING Shielded Metal Arc welding is by far the most widely used of the various arc welding processes. It employs the heat of the arc to melt the base metal and the tip of a consumable flux covered electrode. - Page 5 TIG WELDING TIG welding Is primarily a DC current process, but can also utilise AC, usually for very thin materials and when welding Aluminium or other non ferrous metals. It uses a non-consumable tungsten (or tungsten alloy) electrode, held in a torch. Shielding gas (100% Argon), is fed through the torch to protect;...

Page 6: General Safety Precautions
GENERAL SAFETY PRECAUTIONS WARNING: As with all machinery, there are certain hazards involved with their operation and use. Exercising respect and caution will considerably lessen the risk of personal injury. However, if normal safety precautions are overlooked, or ignored, personal injury to the operator may result. - Page 7 Be aware that flying sparks or falling slag can pass through cracks, along pipes, through windows or doors, and through wall or floor openings, out of sight of the goggled operator. Sparks and slag can fly 10m. To prevent fires and explosion: keep equipment clean and operable, free of oil, grease, and (in electrical parts) of metallic particles that can cause short circuits.

power source so that good electrical contact is maintained between the conduit and the welding power source enclosure. 2.2 Maintenance of the welding equipment The welding equipment should be routinely maintained according to the manufacturer’s recommendations. All access and service doors and covers should be closed and properly fastened when the welding equipment is in operation. -
Page 10: Safe Operation Of Electric Arc Welders
SAFE OPERATION OF ELECTRIC ARC (MIG, TIG) WELDERS Comply with precautions above and this section. Arc welding, properly done, is a safe process, but a careless operator invites trouble. The equipment carries high currents at significant voltages. The arc is very bright and hot. Sparks fly, fumes rise, ultraviolet and infrared energy radiates, workpieces are hot. - Page 11 Fire & Explosion Prevention Do not exceed the equipment’s rated capacity or overload the arc welding equipment. It may overheat cables and cause a fire. Loose cable connections may overheat or flash and cause a fire. Never strike an arc on a cylinder or other pressure vessel. It creates a brittle area that can cause a rupture or lead to such a rupture later under rough handling.

Page 12: Safety Devices
Cables Frequently inspect cables for wear, cracks and damage. IMMEDIATELY REPLACE those with excessively worn or damaged insulation to avoid possibly lethal shock from bared cable. Cables with damaged areas may be taped to give resistance equivalent to original cable. Keep cable dry, free of oil and grease, and protected from hot metal and sparks. - Page 13 NEVER attempt any electrical or mechanical repair unless your are a qualified technician. If you have a problem with the machine contact your local CLARKE dealer. NEVER use or store in a wet/damp environment. DO NOT EXPOSE TO RAIN.

Page 15: Features Of The Arc/Tig135
FEATURES OF THE ARC/TIG 135 WELDER The ARC/TIG 135 welder has been designed to work with unstable input voltages. The use of power components and of electrolytic capacitors with higher voltage and a special control circuit grant a high welding current stability in spite of the mains voltage fluctuations. - Page 16 ELECTRICAL SYMBOLS DISPLAYED ON THE MACHINE The full technical specification for your inverter is to be found printed in a rating plate on the back panel or underside of the ARC/TIG 135 machine. The meaning of the markings and symbols shown are explained as follows.

WELDING TECHNIQUES ARC WELDING Arc welding cables are supplied with this machine. The kit comprises all necessary cables, plus a hand shield and wire brush with chipping pick. To prepare the unit for ARC welding, it is important that you follow the procedure below. With the ON/OFF switch, located on the rear panel, in the OFF position, connect the welding leads as follows:... - Page 19 Note: If the machine stops at any time and the amber light comes ON the thermal overload has intervened. The most difficult aspect of the arc welding process, particularly for beginners, is that of striking an arc. We strongly recommend that you practice on some pieces of scrap metal to get the feel of the operation, before you start on an actual welding job.
- Page 20 TIG WELDING To prepare the unit for TIG welding, it is important that you adopt the following procedure. Plug the work return lead (earth clamp) in to the +ve terminal, and secure the work clamp tothe workpiece. For good contact, the work clamp must be attached to clean bare metal. Clean with a wire brush where necessary.
- Page 21 Scratch the tip of the electrode on soon as an arc develops, quickly withdraw the electrode to maintain a gap of approx 3-4 mm, and proceed to weld. (See notes below). To stop welding, simply remove the torch from the workpiece. This method is referred to as ‘Scratch Arc’.

MAINTENANCE The ARC/TIG Inverter, requires very little maintenance other than the guidelines shown below. Under normal working conditions removing the covers and cleaning with dry compressed air at reduced pressure once a year will be quite sufficient. Cleaning at more frequent intervals is advisable however, if the unit is operating in a dusty and dirty environment. -
