2. SUMMARY
ARC series (discrete) welder is a MMA arc welder which adopts the insulated gate bipolar
transistor (IGBT) power module.
It can change work frequency to medium frequency so as to replace the traditional hulking work
frequency transformer with the cabinet medium frequency transformer.
Thus, it is characterized with portable, small size, light weight, low consumption and noise etc.
ARC series (discrete) has excellent performance: constant current output makes welding arc more
stable; fast dynamic response speed reduces the impact form the arc length fluctuation to the
current.
There are also some automatic protection functions for under voltage, over current, over heat,
etc. inside the welders, when the problems listed before occurred, the alarm on the front panel is
light and at the same time the output current will be cut off. It can self-protect and prolong the
using life and greatly improved the reliability of the welders.
ARC series can be ignited easily, also with little splash and good weld bead.
ARC series (discrete) is widely used in Petroleum, chemical, mechanical, shipbuilding,
architecture, boiler, pressure container, war industry and installation and so on. This machine has
high duty cycle even in the 40
℃
, which can keep the continuous operation. The frame is Stability
of the machine, which can keep working under high temperature and corrosion environment.
