When the welding wire emerges from the torch, there is a high risk of
injury (the wire may pierce the welder’s hand. injure his face and eyes)
For this reason, when feeder-inching etc., always hold away from your
body (machines with wire feeder)
Strong arc burns the eyes and skin
The UV rays generated by arc will damage skin and eyes, please wear
welding labor clothing when welding
Protect the eyes and face from UV, heat and flying sparks with an
appropriate safety shield containing appropriate regulation filter glass
Wear a pair of appropriate regulation goggles (with side guards) behind
the safety shield
Cylinder s may hav e a pote ntial ris k of

Protect shielding-gas cylinder from excessive heat, mechanical impact,
slag, naked flames, sparks and arcs
Place cylinders preferably away from the welding site and fasten them
firmly
Never hang a welding torch on a shielding-gas cylinder
Never perform welding on a pressurized shielding-gas cylinder
Use only shielding-gas cylinders that are suitable for the application in
question, together with matching, suitable accessories (pressure
regulator, hoses, fitting and hose clamp)
When opening the valve of a shielding-gas cylinder, always keep your
face away from the outlet nozzle
When the shielding-gas cylinder is not connected up, leave the cap in
place on the shielding-gas cylinder valve

When current flows through a conductor or TIG welding, high
frequency arc is generated, which will induce an electromagnetic field
(EMF). When welding, the welding cable around will form the
electromagnetic fields
Electromagnetic fields may interfere with pacemakers and other medical
equipment, if the welders wear such equipment, please consult a doctor
before the welding operation
Electromagnetic field may cause as yet unknown damage to health, in
order to minimise electromagnetic damage, please try to do the
following points:
Keep the cables as short as possible
Arrange the cables so that they run close together (to prevent EMI
problems as well)
Do not arrange cables around the body
Try to ensure the cables connecting machines and workpiece are on the
same side of your body
