YD-400AT3DJT HF TIG Welding Machine

Processes:

DC TIG (GTAW)

Stick (MMA)

Industrial Applications (DC TIG):

*Aerospace Industry

*Small diameter ,thin wall tubing for example in

Bi-cycle industry

*Root (first pass) welds for piping

*Maintenance & Repair Work- Repair of Tools

& Dies

Base metals compatible with DC TIG:

*Copper Alloys

*Cu-Ni Alloys

*Stainless Steel

*Low carbon alloys

*Low alloy steels

Arc Force (MMA):

This is a feature used in Stick welding. Arc force is a temporary increase of the output current during welding when the arc is too short. This feature supports operators to achieve consistently excellent arc performance resulting faster & better quality production.

Hot start (MMA):

There is a temporary increase of the output current (0.5 seconds approx.) during the start of welding. Hot Start provides excellent arc ignition without the electrode sticking .

Adjustable Current Down-slope time (Crater fill in TIG Welding): Downslope time adjustable from 0.5 to 2.3 seconds .It supports to fill the crater.

Electric shock prevention switch: This feature is very useful in the wet environment, high altitude, narrow places, welding inside metal containers . When the anti-shock function is used ,the output voltage is about 13V at no-load.
