The Digital Heart of the Machine: an LCD Panel for Full Process Control
The TELWIN PCP 28 LCD 400V spot welder is equipped with a modern control panel with a clear LCD display that forms the command centre of the whole welding process. This is not only an interface, it is an intelligent management system that turns complex technical parameters into simple and intuitive operation. You can set the welding current precisely (as a percentage of maximum power or directly in kA), the weld time (in cycles or milliseconds), the squeeze and hold time, and also the pulse parameters such as the number and duration of the pulses and the cooling time between them.
The LCD panel also lets you store and recall personalised welding programs. This function is invaluable for repetitive jobs or work with different materials and thicknesses. Instead of configuring the machine each time, you only select a stored program, which guarantees identical parameters and repeatable weld quality and removes the risk of human error. The system also shows diagnostic messages, which makes it easier to monitor the machine and solve any problems quickly. Every professional who values efficiency, precision and short downtime will appreciate this solution.
Pneumatic Force and Precision: a Guarantee of an Excellent Spot Weld
A key element that secures the highest joint quality in the TELWIN PCP 28 LCD spot welder is the advanced pneumatic electrode force system. Unlike manual systems, pneumatic force guarantees a constant, precisely controlled and repeatable force through the whole welding cycle. This force is easy to adjust by changing the supply air pressure, so you can match it to the type and thickness of the material being welded.
The right electrode force is critical for the correct course of the welding process. It secures proper electrical contact between the electrodes and the material and keeps the contact resistance low, which concentrates the heat energy where the weld nugget forms. On top of that, constant force during cooling prevents cracks and porosity in the spot weld. For a professional this means less spatter, deeper penetration, higher mechanical strength of the joints and minimal thermal distortion of the material. This is the foundation of reliable structures that also look good.
Water Cooling, the Key to Output and Long Life in Continuous Work
Spot welding, especially at high currents and short cycles, generates a lot of heat that concentrates in the transformer, the arms and the electrodes. The TELWIN PCP 28 LCD is equipped with a highly effective water cooling system that is essential to keep these key components at the right temperature. The transformer windings, the whole length of the arms and the electrodes themselves are all cooled, which keeps them working stably even during intensive production sessions that last many hours.
The water cooling system brings measurable benefits: first, it protects the machine against overheating and prevents damage and failures, which means longer life and higher reliability. Second, keeping the electrodes at a low temperature extends their service life considerably and reduces how often they have to be replaced, along with the related costs and downtime. For a professional who counts on continuous production and maximum efficiency, water cooling is not a luxury but an absolute necessity that keeps the process stable and optimises running costs.

Key Features and Benefits
- Intelligent Microprocessor Control with an LCD Panel: The PCP 28 LCD spot welder is equipped with an advanced microprocessor that manages all the parameters of the welding process precisely. The clear LCD display and the intuitive user interface make it easy to program and select the best settings, such as welding current, pulse duration, electrode force or operating mode (continuous or pulsed). For a professional this means full control over the quality of the spot weld and the option to store personalised programs for different materials and thicknesses, which cuts the setup time sharply, gives absolute repeatability and keeps the risk of errors low even on complicated jobs.
- Pneumatic Electrode Force System: Using a pneumatic cylinder to generate the electrode force guarantees a constant, precisely adjustable force through the whole welding cycle, whoever operates the machine. This system gives the best conditions for forming the weld nugget and removes the problems that come from insufficient or uneven force. In practice this translates into much higher mechanical strength of the joints, less distortion of the material and spot welds that look clean, which is the key in series production and on work that calls for the highest quality.
- High Power (28 kVA) and Welding Output: With a rated power of 28 kVA and a maximum welding current that reaches 15000 A, the PCP 28 LCD model copes without difficulty with thicker steel sheet (up to 5+5 mm) and with stainless steel. The high current output shortens the welding process itself. For the user this means the ability to work with a broad set of materials, higher productivity and the capacity to carry out even the most demanding projects, where a lot of energy is needed to form a solid joint.
- Advanced Water Cooling: Intensive work, in particular at high currents and short cycles, generates a lot of heat. The PCP 28 LCD has an integrated, efficient water cooling system for the transformer, the arms and the electrodes. This solution keeps working conditions stable even during long production runs, protects the key components against overheating and considerably extends the life of both the machine and the consumables (the electrodes). The professional gains certainty of continuous production and minimal service downtime.
- Versatility and Adaptability: The ability to adjust many parameters, among them current, weld time, pulsed mode and electrode force, together with the option of using arms of different length and shape, makes the PCP 28 LCD an unusually versatile tool. The machine can be matched precisely to the specifics of the materials being welded (low carbon steel, stainless steel, galvanised sheet), to their thickness and to the geometry of the parts. For a specialist this means flexibility in taking on varied jobs and a guarantee of good results in typical workshop conditions.
