TELWIN PTE 28 LCD 400V: Professional Spot Welder for Unmatched Precision and Efficiency ✨?
Introducing the TELWIN PTE 28 LCD 400V, a revolutionary microprocessor-controlled spot welder that redefines standards of precision and efficiency in professional workshops. Designed for the most demanding professionals, from automotive sheet metal workers to metal construction manufacturers, this machine is the answer to the need for reliable, fast and repeatable metal joining.
Imagine a job where every weld is perfect and time-consuming corrections are a thing of the past. The TELWIN PTE 28 LCD is not just a tool, it’s your partner in the pursuit of perfection. Thanks to its intuitive LCD panel, control over key welding parameters – such as current, welding time, pressure time or pulsation – becomes extremely simple and precise. Forget guessing about settings; now you’re in full control, which translates into welds of the highest quality, minimized material distortion and significant time savings.
The innovative design of the pneumatic electrode clamping system guarantees consistent and even force throughout the welding cycle, which is key to achieving robust and aesthetically pleasing joints, even in intensive series production. Combined with a robust power output of 20 kVA (rated at 50% cycle) and a maximum welding current of 13 kA, the PTE 28 LCD can easily handle welding steel sheets up to 3+3 mm thick. It’s an investment that pays for itself quickly, increasing the productivity of your plant and the quality of your final products.
TELWIN, as a world leader in welding equipment, has taken care of every detail. Robust construction, high-quality components, and optional water cooling for arms and electrodes ensure long machine life and stable performance even during prolonged operation. When you choose the TELWIN PTE 28 LCD 400V, you are choosing the technology that drives your success. ??️
Explore the Advanced Capabilities of TELWIN PTE 28 LCD 400V
??⚙️ Smart LCD Control Panel: Complete Control in Your Hands
The TELWIN PTE 28 LCD welding machine is equipped with a modern control panel with an easy-to-read LCD display that revolutionizes the way you interact with the machine. Forget about complicated dials and uncertain settings. Here, every parameter is at your fingertips – from the precise adjustment of welding current (in percent), to the precise setting of welding time (in grid cycles), to the current ramp-up time, pre-press and post-press time.
The panel also allows you to select the operating mode: continuous or pulse welding. The pulse mode is particularly useful for welding galvanized sheet metal or high-strength steel, minimizing overheating and improving weld quality. What’s more, the microprocessor allows you to save and recall personalized welding programs. For the professional, this means not only saving time when changing material or thickness, but above all, a guarantee of 100% repeatability of parameters and obtaining identical, high-quality welds every time.
?? Pneumatics and Water Cooling: the Key to Durability and Perfect Welds
The mechanical heart of the TELWIN PTE 28 LCD is an advanced pneumatic electrode clamping system. The pneumatic actuator, controlled by a microprocessor, ensures constant and precisely regulated pressure throughout the welding cycle – from initial positioning to final weld fixation. Adjustment of the clamping force (e.g. via an air pressure regulator) allows the parameter to be perfectly matched to the type and thickness of the materials to be welded, which is crucial for optimal mechanical strength of the joint.
Equally important, especially for intensive work, is a water cooling system for the arms and electrodes. Although a cooling unit is usually an option, its use drastically increases the life of the electrodes, prevents overheating and maintains stable welding parameters even during multi-hour sessions. For the professional, this means less wear and tear on consumables, a more stable production process and the ability to work with higher currents and longer cycles without the risk of equipment damage or deterioration of weld quality.
?? Optimizing the Welding Process for Maximum Efficiency
The TELWIN PTE 28 LCD is not only powerful and precise, but also a tool to intelligently optimize the entire welding process. Features such as adjustable current ramp-up time (slope-up) allow for a smoother start of the process, which is beneficial for materials sensitive to rapid heating. In turn, the ability to operate in pulse mode (with adjustable number and duration of pulses and intervals between them) opens up new possibilities for welding difficult materials such as high-carbon steels or coated sheets, reducing the risk of coating burnout and improving penetration.
For the professional, this means greater application versatility and the ability to take on more complex jobs. Microprocessor control ensures that each welding cycle is carried out exactly according to the set parameters, minimizing the number of misses and the need for corrections. As a result, the workshop gains productivity, lead times are reduced, and material and energy consumption are optimized, which directly translates into increased profitability for the business.

Key Features and Benefits
- ? Advanced Microprocessor Control with LCD Display: The device features an intelligent control panel with an easy-to-read LCD display, which allows precise setting and monitoring of all key welding parameters, such as current (as a percentage of maximum power), welding time (in grid cycles), pre- and post-pressure time, as well as pulse mode (number of pulses and pause time between them). For the professional, this means full control over the process, the ability to save personalized welding programs for different materials and thicknesses, guaranteeing absolute repeatability and the highest quality joints, eliminating the risk of errors and reducing waste.
- ? Pneumatic Electrode Pressure System: An integrated pneumatic actuator provides constant, precisely regulated electrode pressure throughout the welding cycle. This force is independent of the operator, eliminating variability due to the human factor.
