Description:
SPARTUS® ProTIG 400P 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
SPARTUS® ProTIG 400P 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.
