The TELWIN PTE 18 LCD welding machine revolutionizes the spot welding process with its advanced microprocessor control based on FUZZY LOGIC. This intelligent system, available in “EASY” mode, automatically adjusts the welding time and current depending on the material thickness entered by the operator. This eliminates the need for complicated calculations and tests, guaranteeing optimal parameters from the first weld.

For more advanced users, the “EXPERT” mode opens the door to full personalization. The ability to fine-tune parameters such as the percentage of welding current, welding time in cycles, as well as the choice between continuous and pulsed operation, allows the process to be perfectly matched to specific material and application requirements. What’s more, an internal memory for 20 individual programs allows instant recall of stored settings, which is invaluable for batch production or frequent job changes. The result is unparalleled repeatability, minimized errors and significant time savings.

One of the key strengths of the PTE 18 LCD model is the included arms, which are an impressive 700 mm in length. This configuration significantly expands the device’s application capabilities, allowing it to work with parts of large dimensions or complex geometry, where access to the welding area is limited. This is particularly important in the automotive body repair industry, in the production of large control cabinets or space structures.

Equally important is the precise control of the pressure force of the electrodes, realized by means of a pneumatic actuator. The ability to adjust the force (up to 43 daN with 700mm arms at 6 bar) allows it to be perfectly matched to the type and thickness of the sheets to be welded. Too little force can lead to overheating and a weak joint, while too much force can cause excessive deformation and rapid wear of the electrodes. With the TELWIN PTE 18 LCD, the professional is assured that each weld is performed with optimal, consistent force, resulting in high-quality and aesthetically pleasing joints.

The TELWIN PTE 18 LCD welding machine is equipped with an advanced pulse welding mode that responds to the growing demands of today’s industry, especially in the context of processing modern materials. This mode is invaluable for joining high-strength (HSS) and ultra-high-strength (UHSS) steels, which are commonly used in automotive applications to reduce vehicle weight while increasing safety.

Pulsed energy delivery allows for better control of the thermal process, minimizing the risk of losing mechanical properties of the material in the heat-affected zone. It is also ideal for welding galvanized sheets, where a controlled pulse of current helps to penetrate the zinc layer and form a permanent metallurgical bond, while reducing the burning of the protective coating. The benefits for the professional are higher quality and durability of welds, less distortion, reduced risk of corrosion at the joint, and extended electrode life due to less contamination.

TELWIN PTE 18 LCD is not only power and precision, but also intelligent tools to support quality control. The easy-to-read LCD display provides the operator with current information on set parameters, operating mode, and also indicates possible irregularities through an error code system. Integrated thermal protection with a visual indicator protects the device from overloading, ensuring continuous operation and safety.

The ability to save up to 20 personalized welding programs is key to ensuring absolute repeatability of the process. Once the optimal parameters for a given job have been defined and saved, each subsequent cycle will be executed with identical precision, regardless of the operator or time of day. For professional workshops and production facilities, this means standardization of quality, easier induction of new employees and a solid basis for welding process certification.
