The PENWELD 500-A 230V 1550W 173.376 from Leister
The PENWELD 500-A advanced hot air gun features and updated design, producing an excellent ergonomic hand grip for ease of use over long periods of time. Slim, lightweight and with a light weight 3m air hose with 310° air hose rotation, the PENWELD 500-A push-fit model is particularly well suited to harsh environments and tight spaces. Capable of temperatures as high as 600°C. The light weight high quality air hose incorporates the power lead and is robust enough for industrial environments.

Temperature is set via the digital display and the closed loop electronics ensure that the temperature set stays constant no matter what the situation. The control screen can be locked to avoid any accidental changes to the job settings.
The PENWELD 500-A also incorporated a warm colour LED ring light to make it easier to weld in tight dark spaces; the non-fatiguing warm LED colour also prevents eye strain.

As with all Leister tools, the electronic components of the PENWELD 500-A are carefully encased and protected against moisture and contamination.
All PENWELD device variations have a particularly powerful and durable heating element, capable of handling all aspects of hot air draw welding of detailed plastic tanks, air washers, pump wells etc.

Ideal for use with an external air supply such as the Leister ROBUST or AIRSTREAM 100 Industrial Process Blower or compressed supply.

Penweld 500-A 230V 1550W - 173.376 Welding Gun

Leister UNIDRIVE 500 120v Semi-automatic Roofing Heat Gun Welder 163.148
The new UNIDRIVE 500 is a semi-automatic advanced Leister heat gun roof welding machine for single ply (TPO, EPDM, PVC etc) roofing jobs. It has been designed in collaboration with industry practitioners and tradespeople like you to provide a solution for faster job completion but with better quality and more consistent results.

The result was a single ply membrane roofing tool that bridges the gap between Leister heat guns like the TRIAC and fully automatic machines, designed for large scale commercial roofing jobs, such as the VARIMAT V2 and UNIROOF.
The UNIDRIVE 500 provides a balanced application of pressure, through its dual hand/single hand grip design. This makes it very suitable for accurate seam welds around parapets, circle welding and close to the edge welding runs. In addition it has a reversible drive, with the nozzles able to weld in both directions, making this tool superb at detail welding, sky lights, small roof and sloping roof projects. Three nozzles sizes are available: 15mm, 30mm and the supplied 40mm.

The nozzles can be rotated 180º, which in combination with the reversible drive, means the UNIDRIVE 500 can be adapted to various challenging situations.
The UNIDRIVE 500 is a fully digital heat welding tool with full closed loop on temperature, welding speed and blower speed, all managed via the digital display. The brushless motors on the drive and blower mean less maintenance costs and potential downtime.

Not only is the UNIDRIVE 500 capable of welding at speeds of up to 4.5 metres per minute but it does so while producing consistent seams that are significantly stronger than those from Leister heat gun hand tools. With a precise temperature control up to 580ºC, even PVC membrane welding is a breeze.
The image below shows the difference in seam quality and consistency between using a traditional hand tool like the TRIAC (hand welding) and the new UNIDRIVE 500. A major contributing factor is the creation of an air dam during the welding process (much like the bigger industrial machines) which produces a wider, more uniform and consistent welding heat area that bonds a larger width of material.

The UNIDRIVE 500 is between 3x and 5x faster at welding roof membrane than traditional hot air hand tools and as such is estimated to pay for itself in around 1500m of welded seams or roughly 7 small roofing jobs.
Its low service costs and maintenance free motors (blower and drive motors) means it's economical too.
