◆When the power source with cylinder and wire feeder is hoisted, the two equipments should
be unloaded from the power supply first.When moving the power source on the ground, it is
necessary to fix the cylinder with a strap or chain to prevent dumping and injuring people.
◆If the wire feeder is hoisted by lifting lugs for welding, it is necessary to ensure that it is firm
and insulated.

2.1 General
Themachinewith MMAfunction,is digitalfunctionweldingmachinethatapplythe most advanced
inversion technology in the world.
The principle of inversion is to transform the power frequency of 50Hz/60Hz into direct current
and invert it into high frequency (33KHz) through high-power device IGBT, then perform voltage-
drop and commutation with the output high-power D.C power supply via full digital Pulse Width
Modulation (PWM) control technology. Since the switch power inversion technology is adopted,
the weight and volume decrease greatly while the conversion efficiency increase for more than
30%.
Our welding power source can offer stronger, more concentrated and more stable arc. When the
welding rod and work piece get short circuit, its response will be quicker. It means that it is easy
to design welding machine with different dynamic characteristics, and it can even adjust the
characteristics to make arc softer or harder.
The characteristic of the machine is slope. The welding current, push current and heat arc
initiation current use the same knob for synergic adjustment. And with good arc initiation and
stable power output, the welding gap and quality can reach the best effect.
The machine, with small volume, light weight and stable characteristic, can weld stainless steel,
carbon steel, copper and other color metal. Its transfer efficiency is above 85%.
