Electrode welding.

The electric arc burns between the workpiece and a melting electrode. The electrode provides the additional material.

The melting case forms gases and slag to protect the electric arc and melting bath from negative atmospheric influences.

Can be used for almost all weldable materials from approx.

1.5mm on (adapt stick electrodes to the basic material) Transformer devices use alternating current (e.g. SB/SK).

TIG welding.

The electric arc burns between the workpiece and a non-melting tungsten electrode (TIG = Tungsten Inert Gas).

A separately fed inert gas (e.g. Argon (Ar)) protects the welding zone from negative atmospheric influences.

Additional material can be fed manually if required.

The TIG DC (direct current) method is for welding all metals from

0.3mm on, except aluminium and magnesium. (The TIG torch must always be connected to the nega- tive pole).

All inverters (electronic devices) use direct current.

Advantages:

–The electric arc burns more steadily

–Devices can be used with optional torch for the TIG DC welding method

The following applies for setting the welding current in Ampere: electrode diameter x 40 = welding current in Ampere.

The TIG AC method (alternating current) must be used for alu- minium, magnesium and their alloys (breaking of the oxide layer on the material).

The advantage of the method is the good control of the concentra- ted splatter-free electric arc

(= less delay and rework).

MIG/MAG welding.

The electric arc burns between the workpiece and a mechanically fed welding wire (electrode).

An automatically fed non-com- bustible gas protects the electric arc and the melting bath from negative atmospheric influences. The MIG method (MIG = Metal Inert Gas) is for processing alu- minium and aluminium alloys. Argon (Ar), Helium (He) and their mixtures are used as gases.

The MAG method (MAG = Metal Active Gas) is used for processing general construction, tank and

pipe steel from approx. 0.5 mm on in combination with gases mixed from Argon (Ar) and carbon dio- xide (CO2) or from pure carbon dioxide (CO2).

High alloy steel is processed with the MAG method using inert Argon (Ar) gases and a low proportion (< 5%) of carbon dioxide (CO2). The advantages of the method are the easy handling and the excellent thin sheet metal properties.
