ProTig 321P DC

DC inverter TIG welder with a maximum welding current of 320A. Powered by a three-phase 400V mains. The Spartus ProTIG 321P DC tig welder is a three-phase mains-powered inverter TIG welder with a maximum output of 320A at 60% cycle. It is used for TIG DC and MMA welding. The device has all the necessary functions for TIG welding : gas discharge before and after welding, rise and fall of current, TIG PULS function with adjustment of pulse current, pulse width and pulse frequency, selection of operating mode 2T/4T Choice of arc ignition : HF or contact. TIG pulse welding is a process in which the welding current value changes between two values: base current and pulse current. These changes take place cyclically in a certain unit of time expressed in Hertz. In practice, this means that we weld with two currents (lower and higher) so that less heat is introduced into the material and a nice scale is naturally formed. Current sink is a welding function that determines how long the welding current gradually falls to the final level. This allows for a gentle termination of welding and avoids the formation of the so-called crater which is the result of abrupt termination of welding and is considered a serious welding defect. Current build-up is a function of increasing welding current in a certain unit of time. Its function is to prevent excessive wear of the electrode as a result of the rapid increase in welding current. It is recommended to use it when welding with a current of 100 A and above. The device is additionally equipped with 10 memory channels, so that once selected parameters can be saved and used in the future. Modern design, easy-to-read display, numerous welding support functions make the Spartus ProTIG 321 DC an excellent choice for those looking for an efficient and powerful welding source for the TIG method at a reasonable price.
