7. Virtually No Chip Entry! Our machine leaves a “web” in the waterwall, which results in very minimal chip entry into the waterwall tube. Easy Weld Preparation! After penetration is complete, simply remove the “web” using pliers and debur the inside edge. The window is ready for inspection or repair work!

8. Simple Cap Replacement! With our prefabricated replacement caps we’ve dramatically reduced the time to weld up a window.
