Description:
SPARTUS® ProTIG 400PW AC/DC is a modern, digitally controlled inverter welder, constructed on the
basis of IGBTs. Allows welding with TIG AC/DC and MMA AC/DC welding methods up to 400 amps. The device has a
high duty cycle (60%) and is powered with three-phase 400V source power.
The digital function panel provides to precise control of all major welding parameters for both TIG AC and TIG
DC methods:
• TIG process full chart
• AC Balance in the wide range of 10-99%
• AC current frequency in the range 50-250 Hz
• AC wave forms: rectangular, sinusoidal, triangular
• Fully adjustable TIG PULS mode: peak current, base current, pulse frequency, pulse with
• 2T/4T operating mode
And the most important parameters for MMA AC/DC methods:
• Welding current
• Hot Start - easier arc ignition
• Arc Force - better welding in forced positions
The dedicated and integrated liquid cooler unit provides to efficient cooling of the welding torch during
welding with high currents. In addition the liquid cooler unit and welding source are located on a dedicated
cart. Cart has a special platform to gas bottle. It is possible to purchase the welding source without cooler
unit and cart.
SPARTUS® ProTIG 400PW AC/DC will be perfect for welding jobs in industry and manufacturing. Both
during welding steels, stainless steel and aluminum or other alloys
Examples of use: production, industry, constructions.
