STAHLWERK AC/DC TIG 200 Puls ST Welding Machine

Description of the STAHLWERK AC/DC TIG 200 Puls ST Welding Machine

The STAHLWERK AC/DC TIG 200 Puls ST is a multifunction 2-in-1 TIG welding machine integrating TIG AC/DC and MMA (stick welding) processes up to 200 amps. Powered by single-phase 230V, it delivers stable, true output power suitable for industrial environments, maintenance work, metal fabrication, and precision metalwork.

With AC mode, aluminum welding becomes precise and fully controlled. In DC mode, weld steel, stainless steel, copper, and various alloys with clean, consistent penetration.

Advanced Pulse Technology – Full Heat Control

The integrated TIG Pulse function reduces thermal distortion and prevents burn-through on thin materials. Parameters are fully adjustable:

• Pulse current
• Pulse width
• Pulse frequency
• Long Pulse – enhanced penetration
• Short Pulse – optimal weld pool control

Ideal for thin sheet metal and assemblies requiring flawless aesthetic finishes.

HF Non-Contact Ignition

High-frequency (HF) arc ignition ensures clean starts without touching the workpiece. Result: preserved tungsten electrode, uniform weld bead, and superior working comfort.

WP-26F Torch with Flexible Head and Integrated Control

The innovative hose package includes a WP-26F torch with a flexible head and integrated current adjustment wheel. Adjust amperage in real time during welding. The ball-joint connection ensures maximum freedom of movement in all positions.

Professional Operating Modes

• 2T / 4T – Precise welding cycle control
• AC Balance – Adjustment between oxide cleaning and penetration
• Up / Down Slope – Perfect finishing without end crater
• Adjustable Post-Gas – Optimal tungsten electrode protection
• Hot Start – Easier arc ignition in MMA mode
• Anti-Stick – Automatic electrode release

IGBT Technology – Industrial Performance

Latest-generation IGBT transistors ensure high efficiency, excellent arc stability, and a compact design without a heavy transformer. Compact dimensions (449 × 238 × 437 mm) with a weight of only 12.7 kg.

Smart Cooling & Safety

High-performance cooling system with integrated thermal protection. Reliable operation even under intensive use.
