Stahlwerk AC/DC TIG 200 pulse – TIG & MMA welder with pulse function/aluminum welder

The STAHLWERK  AC/DC TIG 200 Pulse ST is a multifunctional 200 amp AC/DC TIG welder with an MMA electrode welding function. One of the many advantages of this combination welder is its compact design and low weight of only 13 kg.  7 YEAR WARRANTY

The AC/DC STAHLWERK TIG 200 Pulse ST has a comprehensive pulse function that facilitates, among other things, the welding of thin sheet metal. Parameters such as pulse current, pulse frequency, long and short pulse are easily adjustable. In TIG welding, the contactless HF ignition enables comfortable work and better welding results.

The AC/DC STAHLWERK TIG 200 pulse ST welder comes with an innovative hose package including a WP-26F torch with a flex head. The WP-26F torch has an adjustment wheel for direct regulation of the welding current and is attached to the hose with a ball joint. This enables maximum flexibility in TIG welding.

Equipment functions & components

• AC/DC TIG welding -A alternating current (AC) and direct current (DC). Welding of almost all metals, such as steel, stainless steel, aluminium, copper and many more.
• 2 in 1 combination unit – TIG & MMA welding is possible up to 200A.
• Extensive pulse function – TIG PULSE- prevents materials from burning through and reduces deformation due to heat, especially suitable for welding thin plates whose material may be heated only slightly. Adjustable parameters are: Pulse current, pulse width, pulse frequency, long and short pulse.
• IGBT technology – The newest and most advanced transistor technology enables high performance welding! No transformer, no MOSFET, state-of-the-art IGBT!
• Lightweight & compact design – only 12.9 kg weight and dimensions of 455 x 220 x 370 mm. Innovative IGBT transistors save space and weight compared to old MOSFET technology. No more heavy carrying!
• HF ignition – enables non-contact ignition and provides much better welding results. No LIFT ARC, no strike ignition!
• Highest Efficiency & Power – Single phase AC power (230V) powers the unit and allows output power of true 200 amps.

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:

1. 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.
2. 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.
3. 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.

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.
