The welder acquires 220V single phase industrial frequency DC power source through the power

switch and rectify through single phase rectifier bridge and then filtered through capacitor to get the

DC current. The 40 KHz AC current is got through the IGBT all-bridge inverter. Then this alternating

current, transformed by the intermediate frequency transformer and rectified by quick recovery

diode, outputs the stable direct current for the welder immediately after it has been filtered by the

reactor. The wire feed speed can be stepless adjusted through the speed adjust knob. The welding

current is easily influenced from the wire feed speed, usually the faster the wire feed speed the

bigger theAmp value under the same voltage.

MIG series use the movable carton like structures: The upper part in the front is equipped with a

welding current regulation knob, abnormal indicator light, working indicator. The back side is

installed with power switch, gas valve connection , cooling fan, power source lead-in wire, breaker.

On the top there is a handle for the convenient of easy transport. When you open the cover, there is

one primary transformer, one piece of printed circuit board. The bottom part is supplied with output

reactor, primary transformer and etc. Installed in the middle part is a radiator with power elements.

- The surrounding temperature range: when welding: -10 + 40 С;

During transport or in storage: -25 +55 С

- Relative humidity: when at 40 С: ≤50%, 20 С: ≤ 90%

- The dust, acid and erodible materials in the air can not exceed the amount required by the norm

(apart from the emissions from the welding process). No violent vibration at the job site.

- Keep from raining when it is used outdoor.

-Altitude no more than 1,000m.

- The oscillation of the supplied voltage should not exceed ±10% of the rated value.
