Alpha DC TIG 400

1. IGBT inverter technology, real digital control, more efficient, precise control, and energy saving;
2. 3 modes in 1: DC TIG + DC Pulse TIG + MMA;
3. Many functions to ensure high quality weld effect:
In DC TIG / DC Pulse TIG welding mode:
a) Remote control
b) High frequency start
c) Lift TIG
d) Gas check
e) Torch operation modes selective: 2T, Slope 2T, 4T, repeat 4T
f) Pulse TIG
In MMA welding mode:
a) Remote control
b) Anti-stick
c) VRD
d) ARC force
4. Whole welding process realize parameter adjustable
In DC TIG / DC Pulse TIG welding modes:
gas pre-flow time, ignition current, current up-slop time, welding current, peak current, base current, current down-slop time, finish current, gas-post flow time, pulse width, pulse frequency
In MMA welding mode:
Ignition current, Ignition time, welding current, ARC force current, anti-stick current.
5. Pulse TTG welding;
6. Store and read function: store or read whole set parameters. Convenient for more than 2 operators use the same welding machine in turn, and good for save excellent whole set parameters;
7. Built-in water cooling system.
