Available in multiple model sizes covering pipe outside diameters from 8mm to 273mm (0.31″ to 10.75″), the Open Weld Head series provides application-specific solutions for everything from small-diameter tubing to larger industrial piping systems.\u003cbr\u003eThe open head design makes these orbital weld heads ideal for applications involving pipe-to-pipe joints, fittings, elbows, flanges, and other welding jobs where enclosed weld heads may not be practical. Select models are also available with AVC (Arc Voltage Control) and oscillation options, providing enhanced weld process control for more demanding applications and helping maintain consistent, high-quality results in critical orbital welding environments.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eFlexible Open Weld Head Configurations for Demanding Orbital TIG Welding Applications\u003c\/h3\u003e\n\u003cp\u003eThe Orbital Service Open Weld Head (OWH) series is designed to support flexible orbital TIG welding configurations across a range of industrial welding applications. Built with a precision regulated motor and gear system, these open weld heads deliver smooth and controlled operation, while helping the operator maintain consistent weld performance throughout the welding process. \u003cbr\u003eOrbital Service’s multiple configuration options allow the system to be adapted to specific process requirements, such as mounting possibilities for cold wire holders and compatibility with gas or water-cooled TIG torch packages. This modular approach allows operators greater flexibility to configure the weld head based on material type, weld procedure, cooling requirements and production demands.  \u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp style=\"text-indent: -18.0pt; mso-list: l0 level1 lfo1;\" class=\"MsoListParagraph\"\u003e\u003cspan style=\"mso-ascii-font-family: Aptos; mso-fareast-font-family: Aptos; mso-hansi-font-family: Aptos; mso-bidi-font-family: Aptos;\"\u003e\u003cspan style=\"mso-list: Ignore;\"\u003e\u003cspan style=\"font: 7.0pt 'Times New Roman';\"\u003e           \u003c\/span\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c!--[endif]--\u003e\u003cstrong\u003eOpen head design\u003c\/strong\u003e – Enables welding on pipe-to-pipe joints, fittings, elbows, and flanges\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFive model sizes\u003c\/strong\u003e – Covers pipe OD from 8 mm to 273 mm for application-specific selection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAVC \u0026amp; oscillation options\u003c\/strong\u003e – Available on larger models for enhanced arc stability and control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRegulated motor and gear system\u003c\/strong\u003e – Delivers smooth, consistent orbital rotation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCold wire compatibility\u003c\/strong\u003e – Supports cold wire holder integration where required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible torch configurations\u003c\/strong\u003e – Compatible with gas or water-cooled TIG torch systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModular system design\u003c\/strong\u003e – Allows adaptation to different welding procedures and environments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial build quality\u003c\/strong\u003e – Designed for reliable use in shop and field conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eVersatility in Demanding Orbital Welding Applications\u003c\/h3\u003e\n\u003cp\u003eOpen weld heads are designed to deliver stable and controlled rotation during orbital welding operations, helping operators maintain consistent weld quality across a range of pipe and tube positions.
