The new Micro Arc Welder

The precision welder for thin material thicknesses in industrial applications Where others stop, we start: The new Micro Arc Welder enables 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 its broad yet finely adjustable power spectrum, the Micro Arc Welder masters even the most challenging welding tasks.

Facts and figures

  • Long-term proven welding curves for all common weldable
    metals and alloys
  • Enormous versatility due to power range from 5 - 1000 A even for very thin material thicknesses
  • High maximum power on demand for penetration depths up to 1 mm (with 1 mm electrode)
  • Spot weld sequence with 3-step selectable speed up to 3.3 Hz
  • High resistance without degradation even at high continuous output

Handpiece, electrode and contacting

  • Stable and agile electrode stroke for fast, easily reproducible welding results
  • Compatible with all Lampert standard and premium electrodes from 0.6 to 1.0 mm
  • Weight-optimized handpiece with high-precision ceramic electrode guide (optional)
  • Minimized power loss at high welding currents: Reinforced connection sockets for contacting tools with safety plug


  • Clear, simple device control with single-screen configuration
  • Fine adjustment of power output from 1 - 100 % for pulse strength
    and 0.1 to 34 ms for pulse duration

  • High-resolution display with 768 x 576 pixels for maximum viewing angle under all environmental conditions
  • Newly designed, patented welding process control preventing welding errors
  • Intuitive one-hand operation even with gloves on

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.

Compelling variability in applications

The Micro Arc Welder accomplishes your joining tasks in industrial metal processing, in the production of electronics, in R&D labs, in repair shops or in mobile applications directly at the customer‘s location wherever precision, reliability, and process controllability is mandatory It was developed for all weldable materials such as stainless steel, various nickel-based alloys, mu-metals, titanium, copper, platinum, gold, silver and in some cases aluminumin material thicknesses down to less than 0.2 mm as Wire, sheet metal 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.

Around the Micro Arc Welder

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 process starts automatically. 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 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

Advantages in daily operation


No special expertise required

  • Simple and intuitive operation – no specialized training required
  • Reproducible and high-quality welding results at any time on all weldable materials
  • Incorrect operation of both the connections and the operating system of the device almost impossible

Robustness and durability

  • High-quality, robust metal housing with practical carrying handle, resistant edge protection and robust, durable surfaces
  • High-quality connection sockets and controls
  • Long service life even under increased load

Economic efficiency

  • No setup times – immediately ready for use anywhere
  • Maintenance free technology
  • Compact size – easy to transport
  • Low costs for consumables
  • Low argon consumption
The Micro Arc Welder makes welding easy
