This article introduces electrode welding as a welding process and clearly explains its mode of operation as well as areas of application.
- The basic process.
- Simple, proven, robust.

In electrode welding, the electric arc burns between the workpiece and a consumable electrode. The electrode therefore simultaneously supplies the filler material. The stick electrode is clamped into an electrode holder and guided by the welder at the joint.
Stick electrodes are generally coated. The coating also melts away and protects the molten pool and the arc from exposure to outside air by releasing gases and forming slag. After the molten pool has cooled, the slag is removed.
Almost all weldable materials can be welded with stick electrodes, e.g. structural steel, boiler steel,
tube steel, cast steel, stainless steel, hardfacing steels, etc. Electrode welding is simple and safe. The
compact devices from RED by Lorch are easy to handle and simple to transport.
Since no gas is required, welding can also be carried out outdoors, even in draughts. Electrode welding machines are used in all sectors, from industry to crafts.
With the latest inverter technology, our devices have top welding properties and are therefore also well suited for special electrodes.
