miniwelder roof3: For Soft and Unsupported Surfaces

Air-Free Hot-Wedge Welding Keeps Membranes Stable

Welding waterproofing membranes on soft surfaces or in areas without continuous support can be challenging, particularly where specific waterproofing requirements apply. The lightweight miniwelder roof3 uses contact welding with a copper or stainless-steel hot wedge instead of blower air. This air-free process helps keep the membrane stable and supports smooth, consistent seams even under these challenging conditions.

Consistent Pressure Without Additional Weights

Its pressure roller applies consistent force during welding without the need for extra weights. Together with its lightweight 4 kilogram body, this allows the miniwelder roof3 to operate smoothly on soft and unsupported surfaces while remaining easy to handle and transport on the roof.

Precise Temperature and Speed Control for Roof Welding

Roof welding conditions can vary with the ambient temperature. The miniwelder roof3 operates at 230 volts with 800 watts of power and is designed for reliable performance in both high and low ambient temperatures and for consistent welds in different conditions. The welding temperature can be set from 60 to 480 °C, while the welding speed ranges from 0.4 to 3 meters per minute.

Key Differences Between the miniwelder roof3 and roof2

Compared to the miniwelder roof2, the miniwelder roof3 is designed for a wider material thickness range of 0.3–1.5 millimeters, compared with 0.3–1.0 millimeters for the miniwelder roof2. It uses a narrower 34 millimeters hot wedge and is available with copper or stainless-steel heating wedges, both equipped with a test channel, whereas the roof2 heating wedges do not have a test channel. The roof3 also features a steel roller for more direct and rigid pressure transfer with higher mechanical grip. Together, these features make the roof3 particularly suitable for thicker materials, while the test-channel wedge design provides an additional benefit for weld inspection and quality control, especially where specific waterproofing requirements apply.

The miniwelder roof3 – Fields of Activity

The miniwelder roof3 is suitable for a range of roofing and membrane welding applications. In addition to flat and pitched roof membrane welding, it can also be used for textile roofing and facade welding as well as thin plastic film welding.
