Product Description
When it comes to designing and manufacturing welders, Röhr have extensive, unparalleled knowledge. They combine breakthrough technologies to produce some of the most advanced and capable welding machines on the market.
Röhr welders are easy to use and perfectly suited to experienced and new users alike. You can carry out a huge range of welding including vehicle’s, fabrication, house maintenance or more unconventional work where specialist materials require more advanced features. Whether it’s aluminium bike frames or a revived passion for steel sculpture, there’s a Röhr for the job and a Röhr for you!

The SMINI-140NI Gives you Röhr Quality
Exceed your Expectations
Röhr welders are built to last with high quality components that will ensure reliability for occasional or regular users. This welding machine uses the latest inverter technologies to dramatically reduce overall footprint. Inverters dramatically reduce the power required to weld by increasing efficiency by 30% and they produce a consistent power supply giving you the most stable welding arc.
Perfect for a Wide Variety of Welding
This welder is multi-use so you can weld low carbon steel, stainless steel and alloys
Dual “2-in-1” Portable Functionality
This welder uses MMA Arc welding which is ideal for most welding needs and is specifically designed to be highly portable due to it’s ultra lightweight design and shoulder strap. The unit produces neat welds that leave you in no doubt that this high quality welder is designed by Röhr.

The Latest IGBT Technology
IGBT is a bipolar transistor with an insulated gate electrode. This semi-conducting device is being increasingly used in power electronics because it combines the advantages of two transistor types: the easy controls of the field effect transistor and the fast switching and high breakdown voltage of the bipolar transistor. The IGBT also offers some robustness against short circuits because it limits the electrical continuity.

Featuring Hot Start
Hot Start automatically boosts the tension at the ignition of the arc, this function facilitates the electrical arc ignition. After ignition, the unit automatically returns to the pre-set voltage.

Anti-Stick
This function helps to prevent overheating of the electrode by switching off the welding current when the electrode sticks to the material.

MMA Arc Welding
MMA is electrode welding with a coated electrode.

Röhr Welders Come with a Variety of Accessories
The welding machine arrives with a secure lock carry case to store your Röhr Welder with the range of accessories to suit your welding needs. The welder comes with an MMA stick welding clamp (2 metre cable), earthing clamp (1.5 metre cable), long reach strap and wire brush. Also, the unit has a 1.5m electric cord so you can position your welder in a convenient place.

Stick Weld Clamp 2m

Earthing Clamp 1.5m
