Small Diameter

Operator Qualification

The Small Diameter Operator Qualification session prepares students who work in small diameter applications from ½" CTS to 6" DIPS (16mm to 180mm) to understand the theory of fusion and properly fuse small diameter pipes and fittings. Participants go hands-on with our smallest machines, the Mini-Mc® and 1LC, and learn saddle fusion techniques on the Sidewinder®. The course also covers some of McElroy’s most popular machines, such as the Pit Bull® 14, 2LC and Pit Bull® 26.
