STAHLWERK AC/DC TIG 200 ST Digital 3-in-1 Welding Machine

200A AC/DC TIG Welder: Total Control of Aluminum and Steel

TIG DC – Precision Welding for Steel and Stainless Steel

Infinitely adjustable current range from 10 to 200 A to perfectly match power to material thickness and type: steel, stainless steel, copper, brass, and various alloys. Ideal for industrial fabrication, maintenance work, and precision metal construction.

TIG AC – Specialized for Aluminum and Light Alloys

Advanced control of AC frequency, AC balance, and cleaning current to effectively break oxide layers. Result: controlled penetration, uniform weld bead, and clean finish—even on demanding workpieces.

• 4 AC waveforms: square, triangle, trapezoid, sine
• Precise adjustment of penetration and arc behavior
• Optimized bead width and improved arc sound characteristics

MMA / Stick Welding Mode 30–160 A

Perfect for on-site work and outdoor environments.

• Hot Start: easier arc ignition
• Anti-Stick: reduces electrode sticking
• Compatible with a wide range of standard electrodes

Integrated Clean Mode – Electrochemical Stainless Steel Cleaning

The Clean mode enables electrochemical cleaning, passivation, and finishing of stainless steel weld seams.

It removes heat tint and oxidation to achieve:

• Smooth and uniform surface
• Visually clean welds
• Improved corrosion resistance

The required carbon fiber brush and electrolyte are not included.

Particularly suitable for equipment manufacturing, railings, stainless steel structures, and visible industrial environments.

Spot & Repeat Function – Perfect Control for Thin Sheets

The Spot mode allows reproducible tack welds with reduced heat input. Ideal for automotive bodywork and thin sheet metal.

The Repeat function enables repetitive welding cycles for smooth and consistent series work.

Color LED Digital Control Panel – Advanced Professional Settings

The structured digital interface provides precise control over every parameter:

• Pre-gas (0–2 s)
• Start current
• Current upslope
• Main welding current
• Current downslope (up to 25 s)
• End current
• Post-gas

Non-contact HF ignition protects the tungsten electrode and ensures clean arc starts, even in hard-to-reach areas.

2T / 4T modes for optimal comfort during short or long welds.

Work memory 0–9: store up to 10 complete configurations for instant recall.

Remote control connection compatible with WP26FR (not included).

IGBT Technology & ST-Guard Construction

• High energy efficiency
• Stable and consistent arc performance
• Optimized power consumption
• Intelligent cooling for extended operating times
• Overheat protection
• Robust ST-Guard housing

Compact design for easy transport, perfectly suited for both workshop use and mobile operations.
