TELWIN MODULAR 20 TI: accurate spot welds with dependable precision.
Picture a day in the workshop where every metal joint has to be made quickly, cleanly and with full repeatability. Time is money, and the quality of your work is your reputation. The TELWIN MODULAR 20 TI 230V spot welder was built for exactly that, a compact but strong tool that changes the way you join thin sheet. Skip the compromises and take a proven Italian design that professionals around the world have trusted for years.
The TELWIN MODULAR 20 TI is not only a machine, it is a dependable partner in precise spot welding. With its single phase 230V supply it is ready to work in almost any workshop and offers the power and control needed for durable, tidy joints. At its heart is an electronic weld time control system that holds the right parameters for every spot and removes the risk of burning through the material or leaving a weak, short lived joint. Whether you restore car bodies, build light steel structures or run projects that call for precise joining of small parts, the MODULAR 20 TI gives you the results you expect.
In designing this model the Telwin engineers focused on ergonomics and ease of use. The plain control panel lets you set the best weld time in seconds, and the solid yet light body makes comfortable work possible even in places that are hard to reach. The machine was built to stand up to intensive use in demanding workshop conditions. Least effort for the operator, most efficiency and repeatability, that was the thinking behind the MODULAR 20 TI.
Money spent on the TELWIN MODULAR 20 TI is money spent on output, quality and peace of mind. Every spot weld is made to a high standard, which shows in customer satisfaction and in the profitability of your business. Join the professionals who trust the Telwin brand and see what the MODULAR 20 TI can do for your work.
Capabilities of the TELWIN MODULAR 20 TI 230V
Precision and repeatability through time control
The secret of good spot welds made with the TELWIN MODULAR 20 TI is its electronic weld time control. Unlike simpler machines, where the time is often set roughly, the MODULAR 20 TI uses a precise timer that allows adjustment down to tenths of a second (range 0.1 - 1.2 s). That matters above all on thin sheet, where even a small deviation in time can burn through the material or leave the joint too weak.
With this control the user can count on every spot being the same in quality and strength. It removes the need for time consuming corrections and cuts material waste. Repeatable parameters are the base of productive work, above all in series jobs such as the production of small metal parts or body repairs, where every detail and consistent workmanship count.
Telwin reliability: built for intensive work
The Telwin brand has stood for quality and reliability in the welding trade for decades. The MODULAR 20 TI carries that tradition on with a solid structure and components made for intensive use in demanding workshop conditions. The housing was designed to protect the internal mechanisms against mechanical damage and dirt, which extends the life of the spot welder.
The internal circuits, including the transformer and the control system, are made of good quality materials, which gives stable operation and resistance to overload. Built in thermal protection guards the machine against overheating, which matters during long sessions or in high ambient temperatures. Choosing the MODULAR 20 TI means a tool that will serve you for years, with less downtime and lower service costs.
Ergonomics and versatility: your partner in every task
The TELWIN MODULAR 20 TI was designed around the comfort and efficiency of the operator. Its light, handy construction makes it easy to manoeuvre, even in places that are hard to reach, which is worth a lot during complicated body repairs or when fitting parts of unusual shape. The ergonomic grip holds firmly and reduces hand fatigue during work.
The simple, clear control panel lets you match the welding parameters to the job in seconds, without leafing through complicated manuals. Interchangeable arms and electrodes (available as accessories) widen the use of the machine further and let you adapt it to welding various shapes and profiles. Whether you are a car body repairer, a structural fitter or a craftsman, the MODULAR 20 TI will meet your needs and become a tool you rely on every day.

Key features and benefits
- Electronic weld time control: The spot welder has a precise microprocessor controlled timer that allows the current flow time to be set exactly within a range from 0.1 to 1.2 seconds. For a professional that means full control over the process and spot welds of repeatable strength, with no risk of overheating or of insufficient fusion, which is decisive on thin sheet, for example in car body repair.
- High welding current and efficiency: Despite its compact size and single phase supply, the MODULAR 20 TI produces a maximum welding current of 3800 A. That current joins two steel sheets up to 1.0 + 1.0 mm thick quickly and securely. It saves a lot of time and energy, raises workshop productivity and opens up a broad scope of jobs.
- Adjustable electrode force: Electrode force can be set within a range of 40-120 daN (with the standard 120 mm arms), which lets you match the parameters to the thickness and type of the material. Precise force is needed for correct electrical and mechanical contact, which limits sparking, gives even heating and keeps the quality and mechanical strength of every spot weld high.
- Single phase 230V supply: The standard single phase 230V supply makes this spot welder very flexible. It can be used in practically any workshop, with no need for a three phase installation. That is a real gain for smaller shops, mobile service units and for professionals who value flexibility and easy adaptation of their equipment to different working conditions.
- Compact and ergonomic construction: Small dimensions (440x100x185 mm) and a fairly low weight (10.3 kg) make the MODULAR 20 TI handy and easy to manoeuvre. The ergonomic grip and the well balanced body reduce operator fatigue, even during longer sessions, which matters when making a series of spot welds or working in awkward positions.
Product applications
- Body repair work on car bodies (spot welding of thin steel sheet)
- Small series production of thin sheet parts (housings, brackets and similar)
- Assembly and workshop jobs that call for precise joining of sheet
- Joining bars of small cross section (with suitable electrodes)
- Spot welding of galvanised and stainless sheet (allowing for the material and the right settings)
