Otto Arc 0.25-1.5” Closed orbital weld head. Compatible with Arc 180 and Arc 220 power supply

🔥 Introducing the TPWH C1.5 Orbital Weld Head The TPWH C1.5 series orbital weld heads deliver consistent and repeatable fusion (TIG) welds for tubes, thin wall pipes, and fittings up to 1.5″ (38 mm) OD and standard wall thicknesses up to 0.025” – 0.160″ (0.635mm – 4 mm).

Its ultra-narrow width design makes it the ultimate choice for confined spaces, high-density installations, and tight-fit welds—making previously impossible welds routine.

✨ Precision and Performance for High-Purity Applications For extra convenience and unmatched precision, the TPWH C1.5 weld heads come equipped with independent two-sided clamping system. Precision machined and engineered to easily adjust to any minor diameter discrepancy, providing strong, concentric clamping force for flawless alignment every time.

Additionally, the weld head features integrated water-cooling, making it ideal for continuous, long duty-cycle operations

🔩 Versatility and Support The TPWH C1.5 is a solid option for small diameter tube, with an optimal OD range of 0.25″ to 1.5″ its suitability for diverse applications in industries like semiconductor, pharmaceutical, and aerospace.
