In January 2024, Leister launched the PENWELD A and PENWELD S hot air welders.

Much to the delight of all equipment and container builders, because the handy devices are perfectly suited for precise work on plastic tanks and similar items.

Advanced illuminates the darkness:

The PENWELD A (for Advanced) has a ring-shaped work light directly integrated into the handle. The warm white LED work light,

which is very gentle on the eyes, ensures ideal illumination for the welding zone. This is particularly suitable for prolonged welding work that requires a high level of concentration. 

Easy-to-use polygon handle:

Thanks to the ergonomic design of the polygon handle, the PENWELD A sits comfortably and firmly in your hand when working. This helps in particular with guiding the device – and looks cool too.

Air hose that glides over edges like a snake:

Allow us to say a few words about the air hose with integrated power supply. The surface of the air hose is reminiscent of snakeskin and is extremely slippery.

This means you can pull the hose over any edge without resistance when welding. And the 310-degree rotatable connection offers unprecedented mobility during draw welding.

Easy operation via the display:

What else? Very important: The intuitive menu navigation via the display makes operating the PENWELD A child’s play. The current actual and target values are always in view on the clear display during use.

Another plus for you: Due to the electronic control of the forced air welder, the temperature remains constant, which offers you a high level of process safety.

PENWELD S: Standard impresses with its robustness in harsh everyday industrial life:

The PENWELD S (for Standard) has an impressively compact design. Robust and simply built, the solid, forced-air-driven PENWELD S is ideally suited for you as a tank and container manufacturer for continuous plastic welding. As with the PENWELD A, the PENWELD S has a powerful and durable heating element. All of this makes it the perfect hand tool for high-speed hot gas welding of intricate plastic tanks, air washers, plastic boats, pump shafts, plastic pipes, and much more.

Precise temperature setting with recessed knob:

Although the PENWELD S does not have a display, the temperature setting knob embedded in the handle allows very precise temperature setting. It also prevents unintentional adjustment, which in turn increases your process safety. As usual with Leister, the electronic components are specially encased, thus offering excellent protection against moisture and contamination.

Sturdy air hose for harsh industrial conditions:

Is there anything else that sets the PENWELD S apart from its big brother, the PENWELD A? Yes, namely the air hose (with integrated power cable). This is particularly sturdy in the S version, with its durable design for harsh industrial environments. As with the PENWELD A, the air hose of the PENWELD S also has a 310 degree rotatable connection, allowing you to flexibly guide the unit while welding.
