1. Safety
Welding may cause damage to you and others. Please take good protection during welding. Please refer to the
operator safety guidelines in conformity with the accident prevention requirements of the manufacturer for more
details.
Only qualified personnel can operate this machine!
Please use welding protection appliances approved by national safety
supervision department.
All operators must be licensed and valid special operating personnel for
metal welding & cutting jobs.
Please cut off power supply while maintaining.
Electric shock-may result in serious injury or even death!
Install grounding device according to application standard.
Do not touch live parts with naked skin, wet gloves or wet clothes.
Be sure you are insulated from ground and work piece.
Make sure all your working conditions are safe
Fume and gases can be dangerous!
Keep your head away from fumes and gases while in welding.
Please use enough ventilation or exhaust to keep fumes and gases away
from the breathing zone.
Arc rays can burn!
Use suitable shield and clothing to protect your eyes and body.
Protect other nearby personnel with suitable, non-flammable screening
from being injured.
Improper operation may cause fire or explosion.
Welding spark may cause fire. Please make ensure there are no
inflammables in welding area, and always be alert to fire safety.
Make sure there is fire extinguisher readily available and welders are
well trained to operate the fire extinguisher.
Do not weld air-tight container.
Do not use this machine for pipe unfreezing
Weld materials can burn.
Do not touch hot work piece with bare hands.
Cool the welding torch after continuously working.

Excessive noise can be harmful to hearing.
Wear ear covers or other hearing protectors when welding.
Give warning to nearby personnel that noise may be potentially
hazardous to hearing.
Magnetic field can be harmful to pacemakers.
Electric current flowing through any conductor creates electric and
magnetic fields. Welders having peacemakers should consult their
doctor before operating this equipment.
Moving parts may injure your body.
Please keep away from moving parts (such as fan).
All door, panel, cover, baffle plate, and other protective device should
be closed and well located.
