ZX7-ST series of digital controlled IGBT inverter DC MMA TIG weldingmachine

Features:

1.Can be realized both DC TIG and MMA operations.
2.Adopting digital-controlled, both small and big current can realize stable welding quality.
3.Human-computer interface, in order to easy and convenient adjustment parameters.
4.Manual welding, adjustable inflection point voltage, suitable for the length of cable welding. Adjustable striking
arc time, more easily.
5.TIG welding, have locking and non-locking function, gas per-feeding, striking current, upslope and down slope
time, stopping current, Gas lag-cutting time for adjustable, wind-cooling /water-cooling torch for choice.
6.This machine particularly suitable for the use of the factory.
