MR45H - CK Worldwide MR45H 45-Degree Head for MR140/MR70 Micro Torches

Maximize Accessibility with the CK Worldwide MR45H 45° Head

The CK Worldwide MR45H is a specialized 45-degree torch head designed exclusively for the CK Micro Torch series, including the water-cooled MR140 and the air-cooled MR70. For professional fabricators and industrial welders, the Micro Torch series represents the gold standard for accessing restricted areas. The MR45H head extends this capability by providing a fixed 45-degree angle, which is often the optimal geometry for pipe welding, root passes in tight bevels, and complex structural repairs where a straight or 90-degree head simply cannot provide the necessary electrode angle.

Constructed from high-grade materials, the MR45H is built to handle the amperage ratings of the compatible torch bodies (up to 140 amps for the MR140 and 70 amps for the MR70) without compromising on size. The head is significantly smaller than standard 2-series or 3-series torch heads, reducing the overall footprint of the torch front end. This reduction in size allows the welder to manipulate the torch inside small diameter pipes or between closely spaced components without arcing out against surrounding metal or losing gas coverage due to obstruction.

One of the key features of the Micro Torch system is the modularity. The MR45H features a threaded connection that allows it to be quickly installed or removed from the torch body. This modular design means a single torch cable assembly can be adapted for multiple scenarios simply by swapping the head. This 45-degree variant is particularly useful for walking the cup in small spaces or for freehand welding where the angle of attack needs to be shallow relative to the workpiece.

Welders Supply Company recommends the MR45H for any professional utilizing the CK Micro Torch system. It is a genuine OEM part, ensuring perfect thread fitment and electrical conductivity. It utilizes the specific Micro Torch consumables (collets, chucks, and nozzles), which are designed to maintain the low profile of the assembly. Whether you are in aerospace, motorsports, or tool and die repair, the MR45H provides the geometric advantage needed to execute flawless welds in the most challenging environments.
