Intelligent power source (New model) by whole digital microprocessor control bases on the digital
platform of DSP (hardware main control circuit) and ARM (digital communication panel). It adopts
modular design concept and with characteristics of digital, intelligent, automation, network and
green to provide a new experience for the user. The welder can be upgraded conveniently and add
new functions by software without the hardware change.
Power input : 3 phase 220V is optional for all TD-Series welding machines.
Main characteristics:
● Digital setting for precise control, current is adjusted in units of 1A, 12 welding parameters can be accurately set to achieve high quality welding
● TIG welding 5A arc ignition, stable welding, arc concentration reached the international advanced level
● MMA, DC TIG, pulse TIG, TIG spot welding for multi-purpose
● MMA welding can be set as low no-load output for easy TIG welding
● Two kinds of arc-ignition methods: HF and Lift for TIG
● With line energy monitoring related functions, USB interface is reserved to export data
● Optional 10 welding methods, the welding sequence can be adjusted according to user needs to adapt to welder operating habits and process requirements
● Suitable for the industries of nuclear power, chemical construction, thermal power
● Small size, light weight, easy to carry
