Induction heating specialist, Inductor Innovations, has produced a beginner’s guide to best practices for using its Inductor Pro-Max Kit and Glass Blaster attachment for removing windscreens and other bonded glass. 

Before starting the process it is recommended that the technician carrying it out practices by taking windows off a salvaged vehicle. Practicing will help to familiarise the technician with the weight of the tool and how it operates. Inductor experts also suggest starting on lower power. Once familiar with the tool, the user can use more power to remove glass more quickly. 

The Inductor Pro-Max Kit comes with multiple attachments including the Glass Blaster attachment, the Concentrator and the Fast-Off Pad. The portable kit also comes with two L-wedges to aid with glass removal and a foot pedal that controls the power output.

Step One: locate the urethane bead on the underside of the glass, using the L-wedge. From inside the car, push the flat end of the L-wedge between the glass and pinch weld until it hits the urethane. This is the area that requires heat. It is best to start further inside the glass, which will give more control over the tool.

Step Two: mark the outside of the glass where the urethane is, so the user can see where to heat. This should be done on all four sides of the window.

Step Three: is optional and is designed to prevent the paint from overheating by spraying water or the Cold Shield Thermal Spray Gel around the window. Spray the frame and remove the excess off the glass.

Step Four: Starting in one of the corners of the glass towards the inside edge of the window, step on the foot pedal to activate the unit. Move the attachment back and forth over the urethane in a six-inch section. While holding the attachment in one hand, use the other to apply constant pressure to the glass with the L-wedge. The urethane will start to crackle and pop which is a good indication of the bond is releasing. 

Step Five: Continuously apply outward pressure as the attachment is moved. Repeat these steps until the glass comes loose.
