TELWIN PCP 28 LCD 400V + 700MM ARMS: Precision, Power and Reach for Professional Spot Welding
Built for the most demanding professionals, the TELWIN PCP 28 LCD 400V spot welder with 700 mm arms (part number 824206) resets the standard for joining metal. If your daily work calls for precision, reliability and the ability to handle larger parts, this model is the answer. Picture running your jobs smoothly, with every spot weld identical and time consuming rework a thing of the past.
The TELWIN PCP 28 LCD is not just a machine, it is your partner in getting the work right. With an advanced LCD control panel and microprocessor control, you can set and monitor every key welding parameter precisely. No more working by feel. You now have full control over current, welding time and electrode force, which translates directly into the quality and strength of the joints you make. That makes it straightforward to meet even strict quality standards.
The 700 mm arms open new ground. You reach hard to access places without trouble and join parts of considerable size, which matters in the automotive trade, in steel fabrication and in ventilation systems. The pneumatic electrode force system gives a constant and sufficiently high force, which is what you need for uniform and strong spot welds, even during intensive batch work.
When you invest in the TELWIN PCP 28 LCD, you invest in technology that improves your workshop, raises efficiency and lets you concentrate on what matters most, delivering top quality work. This is Italian engineering and years of TELWIN experience gathered in one powerful tool, ready for the demands of modern welding. See what your work can look like with equipment from the top shelf.
Advanced Capabilities of the TELWIN PCP 28 LCD 400V + 700MM ARMS
Intelligent LCD Control: Full Control and a Repeatable Process
The LCD control panel on the TELWIN PCP 28 is the command centre for your spot welding. Forget complicated settings and uncertainty, here everything is clear, readable and within reach. The microprocessor watches over parameter stability continuously and compensates for mains voltage fluctuations by itself, which is what gives you identical spot welds every time.
The choice of operating mode (continuous or pulsed), precise adjustment of the welding current and of the pulse duration (in cycles), and optionally the hold time before and after welding (pre-weld and post-weld hold time), give you the tools to match the machine exactly to the material and its thickness. Storing individual welding programs saves a great deal of time and guarantees repeatability in batch production or when you change jobs often. This is technology that works for you and raises both the quality and the efficiency of your work.
Reach and Force: 700 mm Arms and Pneumatics for the Highest Demands
The 700 mm arms on the PCP 28 LCD are not only an impressive reach, they are a considered design that stays rigid and precise even at full extension. With them you can spot weld large body panels, parts of ventilation systems and other structures where access to the joint is limited. That is a real extension of what you can produce.
The pneumatic electrode force system is the key element. Unlike manual systems, pneumatics give a constant, repeatable and above all sufficiently high force (up to 120 daN at 6 bar). That is what you need to break through the surface resistance of the material, ensure proper contact and current flow and therefore produce a spot weld with maximum strength and minimal porosity. Pressure adjustment lets you match the force precisely to the thickness and type of material you are welding.
Water Cooling: Stability and Long Life in Intensive Use
Intensive spot welding generates a great deal of heat, above all in the electrodes and arms. The TELWIN PCP 28 LCD is factory prepared for connection to a water cooling system (the cooler is available as an optional accessory). That is essential for keeping the process stable during long or batch work.
Effective water cooling prevents the electrodes overheating, which directly extends their life and means you replace or dress them less often. More importantly, it holds a steady temperature in the welding zone and gives repeatable parameters and joint quality from the first spot weld to the last. For a professional that means less risk of defects, higher output and lower running costs over time. Investing in cooling is investing in reliability and uninterrupted production.

Key Features and Benefits
- Advanced microprocessor control with an LCD panel: the clear LCD panel together with a precise microprocessor lets you set every welding parameter easily and accurately, such as current, welding time (in cycles), pulsed mode and compensation. You can store personalised welding programs. For a professional that means full control over the process, repeatability in every spot weld, fewer errors and time saved when changing settings for different materials and thicknesses.
- Pneumatic electrode force system with adjustment: it gives a constant, high and precisely adjustable electrode force (up to 120 daN at 6 bar), which is what you need for proper fusion and minimal material distortion. The pneumatic cylinder acts quickly and reliably. The benefit for the user is the removal of the force variation typical of manual systems, which gives higher quality, stronger and better looking spot welds and less operator fatigue.
- Working arms 700 mm long: they extend the working reach of the machine considerably and let you spot weld large sheets, parts with complex shapes and areas deep inside a structure. That versatility opens the door to more complex projects, above all in the automotive trade during body repair and in the production of large parts.
- Effective water cooling of arms and electrodes: the system, prepared for a water cooling connection (the cooler is an option), removes the heat generated during intensive spot welding. That protects the electrodes and arms from overheating, extends their life and keeps the working parameters stable even in long use. For the welder it means continuous work, fewer stops, lower running costs and steady, high spot weld quality.
- A wide choice of welding modes and adjustments: the choice between continuous and pulsed welding, precise adjustment of current and welding time and optional functions such as current slope up let you optimise the process for many different materials, including low carbon steel, stainless steel and, in pulsed mode, galvanised sheet or sheet with a higher spring factor. That means flexibility and sound results on different types of sheet, with less risk of burn through or weak joints.
