CAUTION
During cutting the speed of the torch movement should be in accordance with the
thickness of the piece to be cut. Excessive speed causes a return of incandescent
towards the torch which shortens the life of the parts of the torch most subject to
wear and tear. The metal fouling on the nozzle should be removed as soon as possible.

◆Height above sea level is below 1000m.
◆Operation temperature range: -10˚C~+40˚C.
◆Relative humidity is below 90% (20˚C).
◆Preferably site the machine some angles above the floor level, the maximum
angle does not exceed 15˚.
◆The content of dust,acid,corrosive gas in the surrounding air or substance
can not exceed normal standard.
◆Take care that there is sufficient ventilation during welding.There is at least
30cm free disstance between the machine and wall.
3.6 Operation Environment
3.7 Operation Notices
◆Read safty instruction and Chapter 1 carefully before attempting to use this
equipment.
◆Connect the ground wire the machine directly
◆In case closing the power switch, no-load voltage may be exported.Do not touch
the output electrode with any part of your body.
◆Before operation,no concerned people should be left,Do not watch the arc in
unprotected eyes.
◆Ensure good ventilation of the machine to improve duty ratio.
◆Turn off the engine when the operation finished to economize energy source.
◆When power switch shuts off protectively because of failure.Don’t restart it until
until problem is resolved.
Otherwise,the range of problem will be extended.
TIG Welding Application Shot
4.1 TIG Basic Welding Technique
Gas Tungsten Arc Welding (GTAW) or TIG (Tungsten Inert Gas) as it is commonly referred
to, is a welding process in which fusion is produced by an electric arc that is established
between a single tungsten (non- consumable) electrode and the work piece. Shielding is
obtained from a welding grade shielding gas or welding grade shielding gas mixture which
is generally Argon based. A filler metal may also be added manually in some circumstances
depending on the welding application.
