Resumen del manual
They keep in close contact with those who know best what good welding equipment is all about: the craftspeople. That is why a Metabo welding device has everything you need. That is a promise, because in addition to designing our welding equipment from start to finish, we also produce and assemble it - from the transformer to the entire electronics. The strictest of quality checks are therefore quite normal and the five year warranty on the main transformer is a logical conclusion. Metabo. Work. Don’t play. 322 | | 323 WELDING TECHNOLOGY | 323 WELDING TECHNOLOGY ALWAYS THE RIGHT TORCH.

TIG welding. ..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). ..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 0.3 mm 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 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. 1.5 mm on (adapt stick electrodes to the basic material) ..Transformer devices use alternating current (e.g. SB/SK). MIG/MAG welding. 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. ..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 Stick electrode Casing Melted zone Gas/slag Core rod Base material Electric arc Inert gas nozzle Flow nozzle Melted zone Electrode Base material Electric arc Inert gas Gas nozzle Tungsten electrode Melted zone Inert gas Base material Electric arc WELDING TECHNOLOGY ficiently.
