TIG Welding Machine STAHLWERK AC/DC TIG 200 ST Digital

Description of the STAHLWERK AC/DC TIG 200 ST Digital TIG Welder

The STAHLWERK AC/DC TIG 200 ST Digital is engineered for precision welding across industrial sectors – from metal workshops to automotive and on-site repairs. This inverter combines AC/DC TIG welding with robust MMA electrode welding, delivering up to 200 A real output in a lightweight, compact 13 kg frame.

Equipped with the latest IGBT transistor technology, this unit ensures high efficiency and low power consumption. The digital display provides complete control of parameters, including:

• - HF ignition for non-contact, high-quality arc starts
• - Spot mode ideal for automotive bodywork – precise tacking, minimal heat distortion
• - Electrolytic Clean function – corrosion-resistant, passivated welds with smooth finish
• - AC-Balance to adjust oxide removal and weld penetration on aluminium
• - 2T/4T operation with pre/post gas settings for full arc control

Whether you’re TIG welding aluminium, steel or copper, or using MMA for structural jobs, this machine adapts with ease. Hotstart and Anti-Stick features make MMA use even more efficient, especially on challenging materials.

Remote control compatibility (for WP26R torch – not included), intelligent cooling, and built-in overheat protection ensure reliable performance in demanding environments.
