Hot-air welding guns
Welding by hot air (hot gas) is the easiest way of welding of thermoplastic materials. The welding is performed by the additional material (welding wire). Advantage of hot air devices is low financial investment and simplicity of welding.
Technology of hot-air welding
Hot-air welding machines are divided into two types- with their own air-blower and without their own air-blower . disadvantage can be a necessity of connection on external air-blower or air distribution. All models of hot-air machines Wegener without their own air-blower are intended only for thread welding jets. With devices with their own air-blower you can appreciate their mobility despite their bigger dimensions. Thanks to the integrated air-blower that supplies air to the device, you can use it everywhere, only connection to the electrical network. Hot-air guns with their own air-blower mostly enable usage of thread and also insertable welding jets.

It is needed to equip a hot-air welding machines with welding extension. Wide range of jets according usage, type of connection to the welding machine or type of welding wire is available. Jets can be divided, according the method of welding, into the welding and fast-welding. Fast-welding jets are mostly used in practice, only in case of areas that are hard to reach, when i t is not possible to use fast-welding jet , the welding one is used. Advantage of fast-welding jets is that they „lead“ a welding wire and warmed it by evenly welded material. Welding is then faster than basic with a welding jet. Fast-welding jet simultaneously helps to develop a constant pressure, during placing of a wire, and thanks to this the quality of final weld is better.
