This company now offers a plasma arc Cutting Guide to make hand-held cutting easier, faster and more efficient. When used with the company's Pro-Cut line it will create repeatable, circle cuts. The manufacturer says this is especially important for hvac shops, since it eliminates the need for costly templates on circle cuts and offers more consistency compared to freehand cutting.
