Kemppi Mastertig MLS ACDC is a family of TIG welding machines designed for industrial use,
with characteristics especially suitable for welding materials like aluminium and stainless steel.
The equipment consists of power source, function panel and welding torch. The cooling unit
Mastercool 30 is used in water-cooled TIG welding. The welding torch can be either water-
cooled or gas-cooled.
Multipurpose power sources Mastertig MLS™ 3000 and 3003 ACDC of 300 A maximum current
is designed for demanding professional welding, suitable for electrode, TIG and pulsed TIG
welding with both direct and alternating current. The power source is controlled with IGBT
transistors with a frequency of approximately 30 kHz, and the operational functions with a
microprocessor.
Mastertig MLS 3000 ACDC is connected to a 400-V three-phase network. Mastertig MLS 3003
ACDC is a multi-voltage power source that operates steplessly in the three-phase range
230–460 V.
Mastertig MLS 3000 ACDC VRD is equipped with so called Voltage Reduction Device (VRD)
function to avoid danger of electric shock. VRD maintains open circuit voltage under 35 V.
