Product information

This product supersedes product no: 670398


  • The UWI-500TP is designed for welding with all types and sizes of welding wires, coated electrodes, carbon electrodes and TIG rods, with current range: 5 -- 500A.
  • Line Voltage compensation keeps output of the power source constant regardless of fluctuation in input power from 10% below lowest to above highest rated input voltage.
  • Total Protection function with indicator light prevents machine damage if one phase in the primary power supply falls out or if over-voltage is supplied to the machine.
  • Thermal overload protection with indicator lights helps prevent machine damage if the duty cycle is exceeded or airflow is blocked.
  • Safe in use. The Voltage Reduction Device function reduces touchable open circuit voltage to only 9V, providing optimal safety for the operator.
  • The remote amperage control can be used for all processes, and also for two machines in parallel for up to 1000 Amperes for Air Carbon Arc gouging.
  • Separate characteristics are available for welding with standard electrodes, for cellulosic electrodes, for TIG, for Air Carbon Arc gouging and for Wire welding with or without shielding gas. This ensures optimal properties for all processes
  • Adjustable Hot Start for MMA welding provides optimal arc striking for all electrode types and prevents electrode sticking.
  • Adjustable Arc Force for MMA welding allows the arc characteristics to be changed for specific applications and electrodes.
  • 2-step TIG-torch control with Lift-Arc provides an easy and soft TIG arc start, and remote control from 5 amp to maximum ensures total arc control both during welding and for the down-slope finish of the weld.
    Adjustable gas post-flow prevents faults in the end phase of the weld.


UWI-500TP are able to perform normal stick electrodes, cellulosic stick electrodes, TIG (with Lift Arc), wire welding and air carbon arc gouging.

5-500A current range covers the use of any size of welding electrodes and parallel connection of two machines provide 1000A for the most power demanding Air Carbon Arc gouging tasks.
