Torch / TIG - Maximum control of the arc

What is a TIG welding machine?

There is often confusion about the terms. A TIG device is technically identical to a identical to a TIG device. The abbreviation TIG stands for Tungsten Inert Gas (English for tungsten), whereas in German we speak of Tungsten inert gas. Regardless of the designation on the housing on the housing: The process remains the same. It is considered the supreme discipline welding process, as the arc Torches without the electrode melting MMA melts away. The welding rod is fed in manually, which gives the welder Gives the welder full control over the weld pool. This is precisely why is precisely why TIG welding is the first choice for visible seams and critical Joints in pipework and tank construction.

The importance of AC and DC in welding

Anyone looking to purchase a new welding machine will inevitably stumble across the terms the terms AC and DC. This distinction is essential for the Choice of material.

• DC (direct current): This is the standard for most most metals. DC TIG is used to weld steel, stainless steel (CrNi), Copper or titanium. The current flows constantly in one direction (usually Negative pole on the MMA), which ensures deep penetration.

• AC (alternating current): If you want to process aluminium aluminium cannot avoid AC. Aluminium forms a hard oxide Oxide layer that has a higher melting temperature than the metal itself itself. The alternating current breaks down this oxide layer in the plus phase phase, while the negative phase provides the burn-in.

A modern AC/DC combination device, often designed as an inverter, covers both worlds Worlds. The settings on such machines often make it possible to precisely adjust the Frequency and balance of the alternating current in order to optimise the Cleaning effect (breaking up the oxide layer) or the burn-in effect (heat input into the material).

Which TIG welding machine and Torch is right for me?

Choosing the right welding machine and torch depends heavily on the application the application. For fine work on thin sheet metal (e.g. 1-2 mm) a gas-cooled Torch is often sufficient. These are lighter and more flexible, as they do not require additional cooling water. However, when working with high Current (over 200 amperes) or in continuous operation, a water-cooled water-cooled TIG torch is required. It prevents the handpiece from Handpiece from overheating and wear parts such as clamping sleeves from wearing out too quickly wear out too quickly.

Another criterion is the hosepack. It must be flexible in order not strain the wrist. A package that is 4 or 8 metres long metres long provides the necessary range of movement, especially when working on large large components and you don't want to constantly tighten the device.

Why TIG welding at all?

Compared to MIG (metal inert gas) or MMA (electric manual), TIG is is slower, but unbeatable in terms of quality. There is no spatter Spatter and the weld seam is visually flawless. In addition the heat input can be extremely finely dosed using functions such as pulse, which minimises Minimises distortion in thin materials.

You can recognise quality by the detail

A good TIG Torch holder is characterised by ergonomic handles and high-quality Handles and high-quality buttons. Professionals particularly favour models especially models in which the wear parts (gas nozzle, Sleeve housing) are internationally standardised so that replacements are available everywhere available everywhere. Whether you are working in your home workshop or in an industrial environment: Make sure that the Torch matches the Gas flow rate and the power of your machine.

So if you want to buy a TIG welding machine, you should budget for a high-quality torch for a high-quality Torch. Because the best AC/DC device is of no use if the Torch is unwieldy or the current contact to the electrode MMA is not transmitted cleanly. Our selection on schweiss-shop.de covers precisely this need for professional accessories - for results that are impressive.
