The Micro Arc Welder
- the universal precision TIG welding machine

The professional precision TIG welder for industry, also for thin material thicknesses. Where others stop, we start: The new Micro Arc Welder enables TIG welding of the thinnest material thicknesses and complex structures in an area that is considered largely unsuitable for conventional TIG welders.

With pre-set parameters for a variety of alloys and metals (such as stainless steel and other steels, different nickel-based alloys, mu-metals, titanium, copper, platinum, gold, silver and partly aluminum) and its broad and at the same time finely adjustable power spectrum, the Micro Arc Welder masters even the most challenging welding tasks in a wide range of industries.

The Micro Arc Welder in a professional check

Stefan Haisch – technical project manager in the aerospace industry and precision welding expert with a passion – has taken a closer look at the new Micro Arc Welder and gives an overview of the most important features of our precision welder for the industry.

Compelling variability in applications

The professional welder “Micro Arc Welder” solves your joining task in industrial metalworking, electronics manufacturing, development lab, repair shop or mobile operations directly at the customer’s site when precision, reliability and controllability are required. It has been designed for all weldable materials such as stainless steel and other steels, various nickel-based alloys, mu-metals, titanium, copper, platinum, gold, silver and partially aluminum in material thicknesses down to less than 0.2 mm as wire, sheet or in a metal mix.

This opens up a wide range of possible applications:

  • Welding of thin material thicknesses
  • Welding of complex shapes and structures
  • Liquid- and gas-tight bonding of metals and alloys
  • Repair welding and weld cladding
  • Electrical contacting of conductive wires and electronic components
  • Fixing/tacking of workpieces for automated soldering or welding
  • Bonding of sensitive surfaces without unfavorable structural or visual impact

…and many more.

Take a look at our application library with numerous practical examples.

All about the Micro Arc Welder - the precision TIG welding machine for demanding welding tasks

The operating principle of the Micro Arc Welder is as simple as it is ingenious

If the electrode tip of the welding handpiece touches the workpiece, the welding device automatically starts the welding process . At the point of contact, a melting of 0.2 to 4.0 mm diameter occurs under inert gas atmosphere (depending on material and setting).

In addition to precious metal alloys such as gold, silver and platinum, many non-ferrous metals such as copper and tin alloys, many steels, titanium and aluminum alloys are also suitable for welding.

All alloys suitable for laser or TIG welding can also be welded with the Micro Arc Welder.

Minimum heat input - joining with minimum material distortion

The Micro Arc Welder uses a micro-pulse process in which the arc is ignited electronically. Under an argon inert gas atmosphere, the electrical energy acts on the weld spot in a concentrated manner for a few milliseconds via a non-melting tungsten electrode.

This reduces heat input to a minimum and produces a permanent joint without the disadvantages of classic joining methods, virtually free of distortion.

The ideal precision welder for industry!

The Lampert welding equipment series: MAW vs. PUK

Lampert’s success story began in 2001 with the PUK for goldsmiths and silversmiths. The Micro Arc Welder is based on the same Lampert welding principle as the PUK and has been specially developed to meet the special requirements of industrial demands. It offers the following advantages over the PUK, among others:

  • 60% higher performance for welding highly thermally conductive alloys and thicker material thicknesses
  • Reinforced connection sockets for contacting tools with safety plug
  • Al welding curves for welding of aluminum alloys (mainly flux-cored welding and surface repairs)
  • Robust housing with impact-resistant corners and carrying handle for mobile usage
  • Wireless connectivity for the operation of mobile eye protection systems
  • Device design for increased service life and power load
