Safe Item

Please do the best safeguard when operator does the welding work, welding work will
be bringing the harm to you and others. Regarding the detailed information regarding
the accident when welding, please check the manual carefully.

There is necessary to have a train for the welding work operator, in order to use this
machine safely.

·using the necessary and good quality safeguard dressing.

·operator should be the person who has enough welding skill and ability to operate the
machine.

·please cut off the power connection when they maintain and repairing being in.

Electric sh o ck -------- it would be issuing the deeply harmful, even die.

·please connect and assemble depending on the application standard.

·please do not touch the electriferous elements when you keep your skin bareness,
dressing the wet gloves or wet clothes.

·please make sure that you, ground and working material would be isolated.

·please make sure your working position is in safe situation

Fume -------- may be harmful for your health

·please keep your head out of the smoke avoid to take in the welding fume.

·while welding working, please keep the ventilation running well, in order to keep the
working condition well for surrounding air

.

Arc light radiation --------- may be harmful for your eyes and burn your skin

·please use the qualified welding mask, dressing the safeguard clothes, to keep your
eyes and body in safe situation.

Product Brief

INMIG IH gas shielded welding machine is the inverter welding machine with the
international advanced inverter technology.
The general principle of it is to make the 50Hz/60Hz AC current into DC current, and
make the DC current into high frequency AC current basing on the high power
electronic element IGBT, whose frequency could be 20KHZ, reducing voltage and
rectification

Character:

1. IGBT inverter technology, current controlling model, high quality, steady

properties.

2. constant voltage output, high adaptability for electricity network （±15%）

3. electronic inductor controlling, less splash, deep weld pool and good forming

4. Hot start with slow wire feeding, welding with globule wiping off, high hot start

success rates.

5. suitable for 0.8mm thickness welding material

6. small size, light weight, simple operation

The efficiency of machine would be above 85%, and machine would be with energy

conservation function
