Product Description

NB Series is an easy-to-use MIG welding machine which is everyman's tool. It is particularly well suited to work with ferrous solid and cored wires, and both for professional welding and for use at home or on a farm. It can easily be moved from one work site to another, and it also adapts to varying welding needs. Before using or doing any maintenance work on the machine, read the operating manual and keep it for further reference

The welding machine is small, efficient and light. It is easy to carry with the help
of two handle. The machine is suitable for a range of different purposes and the possibility to use a long extension cord eases operation in various sites. Welding voltage and wire feed speed are adjusted easily according to the thickness of the welded sheet. Thus, selecting the right parameters is easy.

The machine^'s welding properties are optimum with a steel wire of 1.2 mm diameter. Also, 1.0mm or 0.8mm solid wire or cored wire can be used as filler wire. Note, however, that the machine is designed for steel wire welding only.

In addition to the welding machine, welding outcome is influenced by the piece being welded and the welding environment. Therefore, recommendations in this manual must be followed.
During welding electric current is led with the welding gun's current nozzle to the filler and via that to the welded piece. Earthing cable attached to the workpiece guides the current back to the machine, forming the needed closed circuit. Unrestricted current flow is possible when the earthing clamp is properly attached to the workpiece and the fixing point of the clamp on the workpiece is clean, paintless and rustfree.

Shielding gas must be used during welding in order to prevent air from mixing with the weld pool. Carbon dioxide or a mixture of carbon dioxide and argon is suitable for shielding gas. Some filler wires form a shielding gas from the wire^'s filling as it melts thus eliminating the need for a separate shielding gas.

The welding machine has an overheating protector which prevents operation when the machine is overheated. The machine is also protected from too low or too high supply voltage.
However, there are some risk factors connected to welding. You should therefore read and follow the following safety instructions carefully.

The arc and its reflecting radiation damage unprotected eyes. Always protect your eyes and face with an appropriate welding mask . The arc and welding spatters burn unprotected skin. When welding , always use protective gloves and clothing.

Parts of the machine, such as the end of the filler wire and welding gun , become burning hot during use .The wire is also sharp and moves quickly, so be careful when threading it to place.
    
Never carry the machine on your hand during welding , but place it on an even surface . Do not move the shielding gas bottle when the control valve is in place. Fix the gas bottle securely in an upright position to a separate wall rack or bottle cart. Always close the gas bottle after use.

Welding is always classified as hot work, so pay attention to fire safety regulations. Protect the environment from welding spatters. Remove inflammable material, such as burning fluids, from the vicinity of the welding site and supply the site with adequate fire-fighting equipment.
Take into account dangers caused by special workplaces , such as fire risk and danger of explosion, when welding container-like pieces.

NOTE! Fire caused by sparks may break out even after several hours!
CAUTION! Welding in inflammable and explosive site is strictly forbidden!
