MR90H - CK MR140 90-Degree Micro Torch Head Replacement

Unlock Tight Spaces with the CK MR90H 90-Degree Head

For professional TIG welders, reaching the weld joint is half the battle. The CK Worldwide MR90H is a 90-degree replacement head designed specifically for the MR140 and MR70 Micro Torch systems. When you are faced with a welding job inside a small diameter pipe, a deep mold cavity, or a cluttered assembly, a standard torch simply won't fit. The MR90H transforms your Micro Torch into the ultimate tool for restricted-access welding, providing a perpendicular angle that allows you to maintain proper electrode stick-out and gas coverage even in the tightest spots.

The beauty of the CK Micro Torch system lies in its interchangeability. This MR90H head screws directly onto the torch body, allowing you to customize your setup in seconds. Unlike fixed-head torches, the Micro Torch grows with your needs. If you are working on a project that requires a straight approach, you use a 180-degree head; for right-angle requirements, the MR90H is your go-to solution. This flexibility reduces the need to own multiple complete torch assemblies, saving you money while expanding your capabilities. The head is significantly smaller than standard 2-series (9/20) parts, making it one of the most compact TIG solutions on the market.

Welders Supply Company recommends the MR90H for anyone involved in precision fabrication. It is particularly popular in the motorsports industry for header fabrication, in the medical field for device manufacturing, and in general repair shops where "impossible" welds are a daily occurrence. Despite its small stature, the head is robust and designed to handle the amperage ratings of the MR140 (140 amps) and MR70 (70 amps) bodies respectively. It uses specific micro-series consumables (collets, chucks, and nozzles) to maintain its low profile.

Why Choose the MR90H?

• Ultimate Reach: Get the tungsten exactly where it needs to be without compromising torch angle.
• Versatile Fit: Works with both water-cooled (MR140) and air-cooled (MR70) Micro Torch bodies.
• Precision Control: Smaller size means better visibility and finer control over the weld puddle.
