SAFETY WARNING

On the process of welding or cutting, there will be possibility of injury, so please take protection
into consideration during operation. For more details please review the Operator Safety Guide,
which complies with the prev en tiv e re qu ir e m en ts of the manufacturer.

Electric shock——May lead to death ！！

z Set the earth fitting according to applying standard.
z Forbidden to touch the b are electric parts and electrode with uncovered skin, wet gloves or clothes.
z Make sure you are insulated from the ground and the workshop.
z Make sure you are in safe position.

Gases and fumes——May be harmful to health!

z Keep your head out of the gases and fumes.
z When arc welding, ventilators or air extractors should be used to avoid breathing gases.

Arc rays——Harmful to your eyes, burn your skin.

z Wear suitable protective mask, light filter and protective garment to protect eyes and body.
z Prepare suitable protective mask or curtain to protect looker-on.

Fire

z Welding spa rk may cause fire, make sure there is no tinder stuff around the welding area.

Noise——Excessive noises will be harmful to hearing.

z Use ear protector or others means to protect ear.
z Warn looker-on that noise is harmful to hearing.

Malfunction——When trouble happens, contact with authorized professionals.

z If trouble happens during installation and operation, please fo llow this manual instruction to check up.
z If you fail to fully understand the manual, or fail to solve the problem with the instruction, you should contact the

suppliers or the service center for professional help.

WARNING！

Creepage-protecting switch should be added when using the machine！！！

MACHINE DESCRIPTION

Welding machine is a rectifier adopting the most advanced inv erter te chn ol ogy.

The development of welding equipment benefits from the appearance of the inverter power supply theory and

components. Inverter arc welding power source utilizes high-power component MOSFET to transfer 50/60Hz frequency

up to 100 KHz, then reduce the voltage and comm utate, and output hig h-po wer vo ltage via PWM tec hnolo g y. Because of

the great reduce of the main transformer’s weight and volume; the efficiency increases by 30%. The appearance of

inverter welding equipment is considered to be a revolution for welding industry.

Welding power source can offer stronger, more concentrated and more stable arc. When stick and workpiece get short,

its response will be quicker. It means that it is easier to design into welding machine with different dynamic characteristics,

and it even can be adjusted for specialty to make arc softer or harder.

TIG welding machine is easy for arc initi ation and has the functions of arc initiation current, arc stop current , welding

current, basic value current, current ascending time, current desc ending time, gas delay time, continuous adjustment.

What’s more, pulse frequency and pulse duty can also be adjusted independently. It has the characteristics of automatic

control of arc initiation, arc stop and stable arc, which make the best result for shape and inner quality of the welding

surface. Its exclusive design is specially suitable for bicycle industry.

The machine can be for multi-use, and can weld stainless st eel, car bon s teel, cop per and other col or metal, and als o ca n

use for traditional electric welding. Its transfer efficiency is above 85%.

Thanks for purchasing our products and looking forward to your precious advice, we will try our best to perfect our

products and service.

WARNING！

The machine is mainly used in industry. It will produce radio wave, so the worker should make fully

preparation for protection.
