At the heart of the TELWIN PTE 28 LCD welding machine is an advanced microprocessor control system that, combined with an intuitive panel equipped with a digital LCD display, revolutionizes the way the welding process is managed. Forget about inaccurate analog settings – here every parameter is under your full control. You can precisely adjust the welding current (expressed as a percentage or in kiloamperes), the duration of the current pulse (in grid cycles), the cooling time between welds, and the pressure of the electrodes.

What’s more, the PTE 28 LCD offers a pulse mode, ideal for welding galvanized, paint-coated sheet metal or high-strength steel (HSS/UHSS). Pulsating the current allows for gradual breaking of protective layers and more efficient formation of the weld nucleus, while minimizing material overheating and distortion. The ability to memorize user programs is another step toward work optimization – once defined, the ideal parameters for a specific task can be recalled instantly, guaranteeing 100% repeatability and eliminating the risk of errors. For the professional, this means not only the highest quality, but also significant savings in time and materials.

One of the key strengths of the PTE 28 LCD model is its standard attachable arms of an impressive 700mm length. This design feature dramatically expands the welder’s application spectrum, making it indispensable in situations where standard shorter arms prove insufficient. Imagine working on large automotive body panels, structural components of delivery vehicles, manufacturing extensive control cabinets or complex ventilation systems – wherever deep reach is required, the 700mm arms rise to the occasion.

Thanks to this solution, the welder gains incomparably greater freedom of maneuvering and the ability to reach welding points located deep in the structure or behind obstacles. This is not only convenient, but above all eliminates the need for complicated and often less effective alternative methods. Greater reach also saves time, as it reduces the need for frequent repositioning of heavy or bulky parts. When you invest in the PTE 28 LCD with 700mm arms, you get a tool that adapts to your needs, not the other way around.

Intense operation, especially when welding thicker materials or in batch mode, generates significant amounts of heat in the electrodes and arms of the welding machine. The TELWIN PTE 28 LCD was designed with such challenges in mind, so it is designed to work with an external water cooling system (e.g., a Telwin CRA unit or by direct connection to the water supply with a suitable flow regulator).

Water cooling is absolutely key to maintaining the thermal stability of critical device components. By effectively dissipating excess heat, it prevents overheating of the electrodes, which directly translates into prolonging their life and reducing operating costs. Equally important, the stable temperature of the electrodes guarantees the repeatability of welding parameters throughout the entire, even long, work cycle. The professional can count on consistent weld quality from the first to the last point, without the risk of performance degradation or equipment damage. This is the foundation of reliable and efficient production in industrial settings.
