What is the difference between AC DC TIG and DC TIG welding?
When it comes to TIG (Tungsten Inert Gas) welding, selecting the right type of current is crucial for achieving the best results on your project. Two common types of current used in TIG welding are AC (Alternating Current) DC (Direct Current) TIG and DC TIG. In this product description FAQ, we will explore the differences between AC DC TIG and DC TIG welding to help you make an informed decision for your welding needs.
AC DC TIG Welding: AC DC TIG welding machines offer the versatility of using both AC and DC currents for welding. This flexibility is particularly beneficial when working with a variety of materials.
- AC (Alternating Current): Ideal for welding materials like aluminum and magnesium, AC helps to clean the oxidized layer that forms on these metals, ensuring a clean weld. The alternating current switches between positive and negative, helping to break up the oxide layer on the material’s surface.
- DCEN (Direct Current Electrode Negative): This mode is suitable for welding steels, stainless steels, and other metals. It provides a stable arc and deep penetration for thick materials.
DC TIG Welding: DC TIG welding machines exclusively use direct current. There are two types of DC TIG welding:
- DCEN (Direct Current Electrode Negative): This is the most common form of DC TIG welding, providing deep penetration and a stable arc, making it suitable for thicker materials and steels.
- DCEP (Direct Current Electrode Positive): Less common, DCEP is used for welding thin metals and provides a cleaning action on the material’s surface.
Key Differences:
- Material Compatibility: AC DC TIG welding machines are more versatile, catering to a wider range of materials, including aluminum, magnesium, steel, and stainless steel. DC TIG welding is generally better suited for steel and stainless steel.
- Oxide Cleaning: AC TIG welding provides a cleaning action on the material’s surface, essential when welding aluminum and magnesium. DC TIG welding does not have this cleaning action.
- Arc Stability: Both AC DC TIG and DC TIG offer stable arcs, but the type of current can affect the arc characteristics and welding results.
The main difference between AC DC TIG and DC TIG welding lies in the type of current used and the materials they are best suited for. AC DC TIG welding machines offer the versatility of both AC and DC currents, making them a great choice for a variety of materials, including aluminum, magnesium, steel, and stainless steel. DC TIG welding is typically used for steel and stainless steel, offering deep penetration and a stable arc. STAHLWERKÂ AC/DC TIG 200 Pulse Tig Welder
Choose the right type of TIG welding based on your specific material and project requirements to ensure optimal welding performance and results. Explore our range of AC DC TIG and DC TIG welding machines to find the perfect fit for your welding needs.
Current increase/decrease – prevents the formation of shrink marks (end craters) at the end of the weld.
Gas follow-up (TIG) – protects the tungsten electrode from excessive wear and protects the weld seam from oxidation. The parameter can be set individually and separately. It specifies how long gas should flow after ignition.
Smart cooling & overheating protection – State-of-the-art technology, integrated overheating protection and high-performance cooling enable maximum power to be retrieved.
Innovative hose package including modified WP-26 torch with flex head. The welding current is regulated by means of an adjustment wheel installed directly on the torch. The torch is connected to the hose package via a ball joint. This enables flexible and easy working.
AC-Balance – is a variable setting between breaking the oxide layer (-) and a deeper firing (+). This helps to act on properties of different materials and alloys.
Remote regulation via torch or pedal – the welding current can be conveniently adjusted at any time using the rotary control mounted on the torch. Alternatively, the welding current can also be regulated with our optionally available foot pedal.
Welding current / pulse current – Using the two buttons “Welding current” and “Pulse current”, you can set two different current strengths for a welding process, between which the welding current then always alternates.
Pulse width – The pulse width is used to set how long the welding current assumes the current strength of the pulse current before it swings back to the normal welding current strength.
Pulse Frequency – The pulse frequency sets how often the current intensity alternates between the two set values in a specified time interval.
Longpulse – The weld becomes wider, the heat input is higher and the penetration is deeper.
Shortpuls – The weld pool is easier to control and there is less risk of welding a hole in the plate.
Foot pedal – Remote current control via foot pedal (not included). The foot control mode gives you the advantage of being able to control the current even during the welding process, giving you different options for performing the welding work. The maximum current is set on the device. The foot pedal is set to 10. When the foot pedal is depressed, the unit ignites with a lower current than is shown on the display. As soon as the foot pedal is fully depressed, the set maximum current is reached. The value on the display does not change during this time.
Hotstart – Automatic voltage increase at start for better ignition results.
Anti-Stick – Automatic decrease of welding current when electrode sticks, allowing easy removal.
TIG (Tungsten Inert Gas) – Shielded arc welding with inert/inactive gases such as Argon 4.6 (99.996%). An arc is created between the tungsten electrode and the workpiece in an argon bell. This melts the material and any filler material added. A weld seam is formed.
MMA electrode welding / ARC welding – a universal welding process. An arc causes the electrode to melt, forming the weld. No shielding gas is required, making it flexible to use in any location.
Notice:
The unit is not intended for use in residential areas where power is supplied by a public low-voltage power system. It may be difficult to ensure electromagnetic compatibility in these areas due to both conducted and radiated interference.
