1.2. PROduCT INTROduCTION

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 20 is used in water-cooled TIG welding. The welding torch can be either water-cooled
or gas-cooled.
Multipurpose power source Mastertig MLS™ 2300 ACDC of 230 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 65 kHz, and the operational functions with a microprocessor.

1.3. SAFETy INSTRuCTIONS

Kemppi welding devices conform to international safety standards. Safety is an important issue
in equipment design and manufacturing. Therefore, Kemppi welding solutions are unparalleled in
safety. There are, however, always certain hazards involved in using welding equipment. Therefore,
to ensure your personal safety and the safety of your working environment, carefully read the safety
instructions below and respect them.
Use of personal protective equipment
• The arc and its reflecting radiation damage unprotected eyes. Shield your eyes and
face appropriately before you start welding or observe welding. Also note the different
requirements for the darkness of the screen in the mask as the welding current changes.
• The arc radiation and spatters burn unprotected skin. Always wear protective gloves, clothing
and footwear when welding.
• Always wear hearing protection if the ambient noise level exceeds the allowable limit (e.g.,
85 dB).
General operating safety
• Exercise caution when handling parts heated in welding. For example, the tip of the welding
torch, the end of the welding rod and the work piece will heat during gouging to a burning
temperature.
• Never wear the device on the shoulder during welding and never suspend it by the carrying
strap during welding.
• Do not expose the machine to high temperatures, as this may cause damage to the
machine.
