Make sure that you are insulated from the ground and work piece
Make sure that your working position is safe
Smoke & Gas-may be harmful to health
Keep your head away from smoke and gas to avoid inhalation of exhaust
gas from welding.
Keep the working environment properly ventilated with exhaust or
ventilation equipment when welding.
Arc radiation-may damage eyes or burn skin
Wear suitable welding masks and protective clothing to protect your
eyes and bod.
Use suitable masks or screens to protect spectators from harm.
Improper operation may cause fire or explosion
Welding sparks may result in a fire, so please make sure there are no
combustible materials nearby and pay attention to fire hazard.
Have a fire extinguisher nearby, and have a trained person to use it.
Airtight container welding is forbidden.
Do not use these machines for pipe thawing.
Hot work piece may cause severe scalding
Do not contact hot work piece with bare hands.
Cooling is needed during continuous use of the welding torch.
Magnetic fields affect cardiac pacemaker
Pacemaker users should be away from the welding spot before medical
consultation.
Moving parts may lead to personal injury
Keep yourself away from moving parts such as fan.
All doors, panels, covers and other protective devices should be closed
during operation.

USER MANUAL 3
Please seek professional help when encountering machine failure
Consult the relevant contents of this manual if you encounter any
difficulties in installation and operation.
Contact the service center of your supplier to seek professional help if
you still cannot fully understand after reading the manual or still cannot
solve the problem.
GENERAL DESCRIPTION
Advanced IGBT inverter technology
High inverter frequency greatly reduces the volume and weight of the
welder.
Great reduction in magnetic and resistance loss obviously enhances the
welding efficiency and energy saving effect.
Switching frequency is beyond audio range, which almost eliminates
noise pollution.
LEADING CONTROL MODE
Advanced control technology meets various welding applications and
greatly improves the welding performance.
It can be widely used in acid and basic electrode welding.
Easy arc starting, less spatter, stable current and good shaping.
FEATURES OF ARC SERIES
Efficiency, energy saving, portable, stable arc, high no-load voltage, and
with good compensation of arc force, are able to meet various welding
requirements in field work.
