EXPERT TIG 320 AC / DC is a current source, made in the IGBT technology, intended for TIG and TIG PULS welding with alternating current (AC), direct (DC), and the MMA method with coated electrodes (DC) and (AC). The small size and weight make the device perfect for both workshop and field work.
The device has welding modes: TIG DC, TIG DC PULS, TIG AC, TIG AC PULS, MMA AC, MMA DC.
The TIG DC and TIG DC PULS functions are used for welding stainless steel, carbon and low-alloy steel, copper and titanium.
TIG AC and TIG AC PULS function: allows welding of aluminum and its alloys as well as brass.
TIG 2-LEVEL function: "2-level" current control enables switching between the higher and lower current level by pressing the button on the torch repeatedly.
TIG SPOT function: allows for tacking thin materials.
Thanks to the regulation of the TIG PULS pulse welding parameters, we have an influence on the shape of the weld and the focus of the arc. Pulse welding also allows you to reduce the amount of heat supplied to the material and is used when welding thin materials.
The arc ignition takes place in the non-contact (HF) or touch (LIFT) mode. The LIFT function is used during welding in an environment with a high risk of an influence of electromagnetic disturbances on the environment.
Both with HF non-contact ignition and LIFT touch ignition, we have the option of selecting the button function in the TIG torch between 2-step or 4-step operation (button lock for long welds).
A legible and easy-to-use digital control panel enables precise adjustment of the device, ensures stable parameters and high quality of welding.
The device has 9 places for saving user welding programs.
Digital displays make it easy to adjust the parameters of the welding machine:
initial flow of shielding gas
shielding gas post-flow
heart rate frequency
HOT START value
ARC FORCE value
