TIG welding
In TIG welding, the welding arc is formed between a non-consumable tungsten electrode
and the work piece. The resulting high temperature arc melts the work piece to form a
molten pool into which a consumable filler wire, of a similar alloy composition, is slowly
melted. The molten weld pool and filler wire are protected from the harmful affects of
atmospheric contamination by an inert shielding gas that flows out from the TIG welding
torch ceramic nozzle, at a rate of approximately 8–15 litres per minute. (Gas regulator,
flow meter and pure Argon are not provided in this package).
2. SAFETY INSTRUCTIONS
MinarcTig TM 180 is safe and easy to use. The plastic case is strong and does not conduct
electricity. The machine has inbuilt over temperature protection to prevent use when
thermal protection is established. The machine is also protected against under and over
voltage supply conditions.
However, there are some risks factors connected to welding. Please read these
following instructions and also follow correct operation safety procedures during
welding. Always be aware of others, around the immediate working environment.
Always think of protecting yourself and others from the harmful effects of arc light and
heat radiation, and also resulting welding fumes.
2.1. Use of personal protective equipment
The arc and its reflecting radiation damage unprotected eyes. Always protect your
eyes and face with an appropriate welding shield. Make others aware that welding is
taking place and advise them of the associated risks. The arc and welding spatters burn
unprotected skin. Always wear welding gloves and suitable protective clothing.
2.2. Safe use of the welding equipment
Parts of the equipment such as the welding torch and filler wire become burning hot
during use. The tungsten electrode may also be very sharp and the alumina ceramic will
remain hot for a period after the arc is extinguished. A loosely connected return lead may
also get hot during use – take care!
Never carry the machine during welding. Place the machine on an even, sound
surface. Never store the machine hanging it from the shoulder strap. The strap is for
transporting the machine easily between welding sites, when it is disconnected from the
mains power supply.
Do not keep the machine near or on hot objects, as the plastic case may melt and
damage.
