M280 - developed for modelers

You weld – we take care of the details.

Welding components on and off, applying metal, fixing workpieces before soldering, closing pores, producing seams and much more – no problem with the M280.

Also ideal for welding in the immediate vicinity of heat-sensitive areas.

M280 makes welding easy

The operating concept of the M280 ensures simple and intuitive instrument setting.

1. Select metal group


2. select welding situation

Fine-tune the settings:

Power and welding time can be quickly adjusted to individual needs.

Examples of applications

Here you can see some applications that are possible with the M280.

There are presets for steel/stainless steel and for certain highly conductive alloys. Components can be joined easily and original welds can be reproduced.

For example, welding wire can be applied to certain generally weldable aluminum alloys by means of high-frequency superimposition of welding pulses.

Of course, we also have the appropriate welding rods for you. In our assortment we have various stainless steel wires as well as aluminum and titanium wires, which are used in model making.

Automatic mode or foot switch
Difficult workpiece designs may require even more controlled welding control.
  • By pressing the foot switch for 3 seconds, the foot switch is activated. The automatic function of the M280 is then deactivated.
  • The white symbol in the display indicates activated foot switch operation.
  • Welding is now triggered by pressing the foot switch.

Gas flow
  • The gas valve can be opened to adjust the gas flow.
  • To control the eye protection, it can be activated in intervals.

  • The signal tone that announces the start of the welding process can be activated or deactivated here.

  • Choose your preferred language (English or German).


At home in the model shop

Sensible design for longevity or continuous operation:
  • Passively cooled

    The M280 comes without a fan and without ventilation slots. Passive cooling produces no disturbing noise and is very energy efficient.

  • Dustproof housing

    The M280 features a closed, sealed housing. This means that no metal or polishing dusts generated in the workshop get into the unit. Damage or equipment failures due to otherwise unavoidable deposits are avoided.

M280 product comparison with Lampert industrial welders

Lampert bietet für den professionellen Einsatz das Industrie-Schweißgerät Micro Arc Welder an.

Before developing the Micro Arc Welder, Lampert offered adapted versions of the well-known PUK welder for industrial applications, including the PUK U5.

Read here the comparison test between the M280 and the PUK U5, which was made by a customer independently from Lampert.

Although the PUK U5 has significantly lower performance than the new Micro Arc Welder, this comparison is a good indication and decision-making aid for typical modeling applications from a user’s perspective.

Practical test of the M280 in the trade magazine Truckmodell

A detailed field test of the M280 was published in TRUCKmodell 4/19 – you can find the complete report here.

Nothing has changed in the meantime in terms of the operating concept of the equipment or the welding procedure. For the sake of completeness, we would like to mention that the default settings for materials shown in the article have been changed to steel, HF1 and HF2 for the current devices(instructions p.7/5.2).

The eye protection shown in it is no longer available in the form and we recommend using the optics unit (Art.no. 100 210, ill. see top of page) or one of our welding microscopes (see also our price list “Eye protection systems”).

Accessories and optional equipment

Practical additional system components such as various welding microscopes or welding rods and accessories are available according to your individual needs. Visit our Accessories page.
