Precision fabricators handling aerospace components, intricate pipework, or thin-gauge assemblies constantly struggle with joint access when using standard, bulky TIG tooling. The CK Worldwide Accessory Kit For MR70 + MR140 Micro Torch (AK-MR) solves this restriction by providing industrial-grade, interchangeable modular profiles that allow clear puddle visibility and uncompromised torch control inside highly confined work areas.
3 x Interchangeable Torch Heads (45° / 90° / 180° configurations)
3 x Dedicated Collets (1.0mm, 1.6mm, 2.4mm diameters)
2 x Clear Pyrex Gas Cups
1 x Alumina Ceramic Gas Cup
3 x Non-Consumable Tungsten Electrodes (1.0mm, 1.6mm, 2.4mm diameters)
1 x Tungsten Stick-Out Gauge & Installation Wrench
Interchangeable Modular Torch Heads: Three discrete angular options convert your current setup to match specific spatial constraints, removing the need to bend electrodes or compromise on torch travel angle.
Clear Pyrex Gas Cups: Transparent glass construction provides completely unobstructed sightlines to the weld puddle, allowing total bead control when executing critical root passes in blind corners.
Tungsten Stick-Out Gauge: Threaded calibration tool delivers repeatable millimetre-increment electrode extensions, eliminating shielding gas turbulence and preventing arc instability caused by manual guesswork.
Matching Multi-Size Collets: Three exact-bore collets securely hold the matching tungsten electrodes, ensuring optimal electrical contact and uniform current transfer at varying arc amperages.
Complete overhaul kit for micro-profile TIG welding.
Three distinct angular head geometries for varied approach paths.
Multi-diameter electrode handling from 1.0mm up to 2.4mm.
Dual-material shielding cups including ultra-clear Pyrex options.
Integrated mechanical stick-out measurement gauge.
Direct thread-on fitments for rapid workshop conversion.
High-purity process pipework and manifold fabrication.
Aerospace engineering component fabrication and repairs.
Motorsport exhaust manufacturing using exotic alloys.
Light-duty thin sheet metal assemblies inside specialised production facilities.
Detailed maintenance welding where standard torch bodies cannot physically pass.
When operating with the clear Pyrex cups included in this assembly, always ensure the sealing O-rings are seated flush and entirely free of debris. Any minor thermal distortion or mechanical pinching of the seal allows atmospheric air to bleed into the shielding stream, which causes immediate tungsten oxidation and weld metal porosity when working with sensitive materials like stainless steel or titanium.
Pros:
Excellent Puddle Sightlines: Clear glass shielding cups give operators flawless visibility of the weld pool when operating in restrictive joints.
Rapid Tooling Conversion: The matching mechanical wrench and clear markings allow fabricators to change heads and electrode diameters in under sixty seconds.
Repeatable Arc Setup: The mechanical stick-out gauge establishes exact tungsten extension parameters, which keeps welding procedures consistent across different shifts.
Cons:
Fragile Gas Cups: Pyrex components require careful handling and cannot withstand heavy mechanical impacts or being dropped onto a workshop floor.
Amp Capacity Restrictions: Micro-scale design limits the overall heat dissipation, meaning it cannot be used for high-amperage, continuous heavy plate fabrication.
Is this accessory kit compatible with standard WP9 or WP20 series TIG torches from other manufacturers? No, the components inside this kit are machined with specialised micro-threads and small-scale seating profiles designed specifically for the CK Worldwide MR70 and MR140 micro torch series. They cannot be used with conventional 9, 20, or 17 series torch bodies due to entirely different internal physical sizing.
What are the specific operational limits regarding shielding gas flow and current type for the Pyrex components? The Pyrex cups function efficiently with standard direct-current and alternating-current processes under normal parameters. However, shielding gas flow must be carefully regulated to prevent excessive cold shock, and operators must avoid exceeding the thermal limits of the underlying micro torch body to prevent cracking the glass shroud.
Does this tooling system hold specific compliance certifications for use within professional UK structural environments? This tooling package is fully manufactured in accordance with strict international industrial welding standards and aligns with the performance requirements necessary to maintain workshop compliance. Every component is machined to precise tolerances, ensuring predictable electrical performance that satisfies independent weld procedure audits across the United Kingdom.
