Features:

• Liquid-Cooled for High-Amp Durability: The T4W is built to deliver continuous high-amperage TIG performance with 100% duty cycles up to 450A DC. Water-cooling through bi-flow channels provides optimal temperature control under heavy load.
• Flex-Head Torch Body with Surelok Design: The articulated flex-head allows precise weld access in difficult angles while maintaining strength and electrical integrity through the Surelok rear connection system.
• Heat Zone Isolation & Force-Cooling: This torch integrates advanced cooling at key thermal points—including collet and cup areas—to prevent heat saturation and extend the life of the torch body and consumables.
• Extended Consumable Lifespan: Consumables such as ceramics, gas lenses, back caps, and collets last 5× to 20× longer compared to standard torches, reducing replacement frequency and downtime.
• Tungsten Quick Release System: Swap or reposition tungsten with ease using the built-in ratchet-style clamping system – no tools required and no disassembly needed.
• Digital Trigger Switch with Modular Lead Kit: Comes pre-fitted with a control switch and is compatible with interchangeable potentiometer modules for use with foot pedals or digital control panels.
• Compatible with Advanced Consumables: Supports a wide range of consumables, including standard, gas lens, quartz cups, and high-flow collets – fully customisable for various TIG processes.
• Precision-Built for Professional TIG Systems: Designed for compatibility with high-end TIG welders, including the UNIMIG ENVY ACDC series, this torch is a premium choice for aluminium, stainless, and exotic material welding.
