/MAG welding machine is a high quality and semi-automated arc
welding machine. This product adopts DSP digital control technology,stable performance,with
function of wave control, can realize CO2 welding, CO2 spot welding and MMA welding.It is
mainly applied in welding low carbon steel, low metal alloys and other dark metals. Mixed gas or
flux cord wire can be used to weld stainless steel. NBC series has outstanding characteristics of
thyristor welding machine:
1.1 High quality of welding
Adopts Independent Intellectual Property Rights controlling circuit to ensure the
performance as well as the outstanding dynamic response, which gives an aesthetic weld.
1.2 Outstanding molten globule elimination function, coupled with special arc ignition circuit can
lead to almost 100% arc ignition success.
1.3 Stable welding process
Adopts high-speed feedback circuit, anti-interference system, and anti-internet fluctuation to
fulfill stable welding.
1.4 Electricity saving
Advanced PWM inverter technology and the compensation from the grid voltage greatly
reduce the input voltage hence saves electricity.
1.5 Preset function
Straightforward welding current display, easy operation and is suitable for first time learner.
1.6 Greatly reduces splashing
Adopts waveform control technology, which greatly reduces splashing and enables all
position welding.
1.7 Small size and light weight
Compared to thyristor controlled welding machine, NBC series is much lighter and smaller, the
weight is about 1/6 of the thyristor ones. Good adaptability under all kinds of conditions and
environments.
1.8 Multi-usage
With CO2 welding, MMA welding,CO2 spot welding functions.
