Description
TIGLab Alucup Set – Precision in Aluminum Welding (SR9/20 | 2.0 mm)
Elevate your weld quality with the professional Alucup set, specifically designed for demanding TIG welders. This compact consumables kit is dedicated to SR9 and SR20 torches (both gas-cooled and liquid-cooled) and is optimized for electrodes with a diameter of 2.0 mm.
Why choose the Alucup set?
The Alucup set is more than just standard spare parts – it is a system that improves arc control and gas coverage, which is crucial when welding aluminum and its alloys.
- Superior gas coverage: Specially profiled Alucup ceramic nozzles provide laminar gas flow, minimizing the risk of porosity and contamination in the weld.
- Compact design: Perfectly suited for small SR9/20 heads, allowing for maximum maneuverability and precision in tight spaces.
- Thermal resistance: Alucup nozzles are characterized by high resistance to the temperatures encountered during AC welding, which is essential for aluminum work.
- Complete solution: The set includes all the necessary components to immediately convert your torch and enjoy a new level of work quality.
The set includes:
- Alucup ceramic nozzles (#5 and #6): For perfect gas stream focus.
- Collet body (2.0 mm): Ensuring stable current conduction.
- Collet (2.0 mm): Precise holding of the tungsten electrode.
- Insulator: Specifically designed for SR9/SR20 torches.
- Elegant box (Tigbox): For safe storage and transport of parts.
