The DIGI-ARC 160LT is a MMA arc welding machine featuring the Insulated Gate Bipolar
Transistor (IGBT) power module. Its medium frequency transformer makes it portable,
compact, light weight and with low consumption and noise.
The DIGI-ARC 160LT offers excellent performance. Constant current output makes the
welding arc more stable and a fast dynamic response speed reduces the impact from the arc
length current fluctuation.
Other automatic functions protect from under voltage, over current, over heat, etc. An alarm
on the front panel lights, at the same time the output current cuts off. This can
prolong production use and greatly improve the reliability of the machine.
The machine can be easily ignited with little splash and good weld bead.
The DIGI-ARC 160LT has a high duty cycle – even at 40ºC – for continuous
operation. The machine is very stable and keeps working under high temperature and
corrosive environments.

Summary
ARC LT-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 LT-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 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 LT-series can be ignited easily, also with little splash and good weld bead.
ARC LT-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.
