Our Adjustable Welding Head Assembly is engineered for precision and ease of use. Featuring an internal bearing for smooth operation, this head threads directly into the 40mm hollow welding bar. The M10 x 1.0 male threads connect onto the end of our Euro-style whip. The chrome-plated finish provides superior corrosion resistance, while the knurled design ensures a secure grip, making it easy to attach and adjust by hand. With 360-degree adjustability, you can achieve the perfect angle for your welding needs, and the swiveling brass neck allows for fine-tuned adjustments. This versatile, durable component is essential for achieving optimal results in your welding projects. Works best in bore diameters of 55mm or larger. Purchase WHMN.40 for bore welding 40mm to 60mm holes.
