Leister UNIROOF 700 Automatic Roof Welding Machine 120V 1800W

Description

The all new UNIROOF 700 automatic roof welding machine is the most advanced machine for welding roof membrane yet developed. It is 10% faster at welding than the previous top of the range UNIROOF AT and over 30% faster than the UNIROOF ST.

Not only can the UNIROOF 700 weld roof membrane at speeds of up to 3.3m/min, but this can be achieved at lower temperatures (only 580ºC compared to 620ºC) than those required by the AT model. This not only saves time but creates high quality welds at lower power levels, ideal for construction sites where under voltage can occur. This is only possible because of the newly designed electronics which give the UNIROOF 700 sophisticated power management capabilities.

Eco Mode is a new feature that comes in with the UNIROOF 700, and is able to save up to 30% on energy consumption.

The UNIROOF 700 also comes with the latest LQS quality management data reporting and monitoring system with GPS and WIFI to give fast and accurate weld data of all the welding parameters including weld length and accurate GPS data for start and stop positions.

The machine is designed to overcome many of the issues seen on construction sites ranging from under voltage to lack of knowledge of the welding settings for specific materials and uncertainty of the quality of the welds produced.

Acknowledging the fact that up to 40% of the quality outcome for a weld is down to operator knowledge of the material and welding conditions (temperature, speed, air flow etc), Leister has introduced a new smart welding assistant. By automating the settings for specific materials by scanning a product QR code via the mobile app (Leister has worked with material manufacturers to create QR code labels for products with specific machine ‘recipe’ settings for each product) and monitoring the conditions against these parameters, the quality of roof membrane welding is dramatically improved.

Not only does the machine monitor and measure the roof membrane welding variables to ensure that quality waterproof welded seams are being produced; any variables which go outside these parameters alert the operator and, if activated, can stop the machine to prevent poor quality welds being produced.

Leister also realises that 20% of the quality outcome for a weld is down to the machine. This predominantly comes down to voltage, temperature and nozzle technology. To minimise the affect of these Leisters latest automatic roof welding machine includes closed loop technology allowing constant monitoring and adjustment of output to achieve a constant temperature and sophisticated power management electronics to elegantly handle supply under voltage.

Undervoltage can dramatically affect the quality of any welds. For example on a 120V machine, like the UNIROOF ST 120V, with the temperature set at 620ºC and airflow at maximum, under voltage at 100V can reduce the effective temperature of the weld from 620ºC to 475ºC. With the UNIROOF 700, this level if under voltage would result in a weld temperature of 610ºC.

To improve the quality of the welds even further, Leister has developed a brand new patented nozzle design, the Scraping Nozzle, which will launch with the UNIROOF 700 and UNIROOF 300 and be available to purchase separately.

The new scraping nozzle (optional extra – see 170.119 under accessories & spares further down) creates a 25-30% larger surface area within the weld, a 12-16% wider weld width and produces a much stronger and more robust membrane weld with higher tear resistance and with minimal scorch and spit out of slag on PVC. Not only does the new scraping nozzle improve the physical weld quality it also allows for faster roof membrane welding speeds, lower temperatures and at a lower voltage than previously possible. The new design also virtually eliminates the need for solvents to clean the nozzle, better for productivity and for the environment.
