Ac Tig Welding

TIG welding can be done using AC TIG. For DC TIG was chosen because it results in better penetration welds with a smaller Heat Affected Zone (HAZ) due to less heat input to the metal. DC TIG is also well suited to the Tig welding process. TIG welding, DC TIG/MMA welding, square pulsed AC TIG welding, spot TIG welding.

High quality TIG welding: pulsed function, start current adjustment, continue adjustment of current up/down, crater adopted on/off /repeat functions.

Saving energy: special circuit for energy saving, power supply will be shut down after one minute of welding completed.
