Thermatech MIG/MAG/FCAW Welding Machine Model NB-350D

Equipment Features

Dsp controls all-digital welding machine, which conducts
fine control for current state and realize digitilizing model
of high quality CO2 welding
Full range welding current can realize stable welding effect.
Visual touchable digital panel, parameter setting is simple
and easy for operation.
Rapid and smooth arc striking success rate nearly up to 100%.
Multiple welding functions: 2T/4T arc stopping at intial stage,
spot welding, synergic, individual; 9 channels storage and dispatch.
Can be matched with analog interface or digital interface
connected with root and automatic welding.
High deposition rate, excellent arc compensation function,
welding cable lengthened to 100 meters can also stabilize welding.
Freely set arc characteristics, soft or hard arc can be freely set
by waveform control button to obtain the most suitable arc
status ad required.
