Easily flame cut QT-PLUS® with oxyacetylene or plasma. Hardening will occur at the edge of the cut, therefore it’s beneficial to pre-heat before flame cutting (300°F) or allow enough stock to get below the hardened edge.
The minimum plate temperature prior to thermal cutting should be +60°F.
Note: At JADCO, high-definition plasma is used to burn, and the material is under water to decrease distortion of the heat-affected area. For plates ¾” and thicker, preheat the plate to 300°F to prevent edge cracking. When preheating the plate do not heat directly with a torch, use indirect heat to heat evenly over the entire plate.
