Discover the Advanced Features of the TELWIN CONVERTER 500
Outstanding Performance and Durability in Industrial Applications
The TELWIN CONVERTER 500 is a true workhorse, designed for the heaviest welding tasks in industry. Its solid construction and IP23 protection rating give resistance to dust and moisture, which is essential in production halls, shipyards and open construction sites. The high duty cycle, reaching 350A at 60% and 270A at 100% (at 40°C), allows long welding runs without breaks to let the machine cool down, which directly increases productivity and project efficiency.
The machine has a complete protection system that protects both the welder itself and the operator. Thermostatic, overvoltage, undervoltage and overload protection monitor the key operating parameters and minimise the risk of failure. In addition, the ability to run on power generators (with a voltage fluctuation tolerance of +/-15%) makes the CONVERTER 500 an ideal choice for field crews with limited access to a stable power grid. This means continuous work and reliability you can count on.
Masterful MMA Precision and TIG LIFT Flexibility
The excellent welding results of the CONVERTER 500 come from advanced microprocessor control and a package of smart arc assist functions. In MMA welding, Arc Force, Hot Start and Anti-Stick work together to give exceptional arc stability and easy arc striking and to stop the electrode from sticking. Arc Force adjusts the current dynamically, so you can weld with a short arc even in difficult positions without the arc going out. Hot Start makes it easier to start with any electrode, and Anti-Stick protects the workpiece and the electrode.
For jobs that call for greater precision and weld cleanliness, the CONVERTER 500 offers a TIG LIFT mode. Striking the arc by touch removes the need for high-frequency (HF) ignition, which is an advantage in environments sensitive to electromagnetic interference and reduces the risk of tungsten contamination of the weld. Welding at up to 450A in TIG mode lets you join even thicker components made of stainless steel, copper or titanium, with welds of excellent quality and appearance. This versatility meets the expectations of the most demanding welders.
Smart Inverter Power: Savings and Mobility
The TELWIN CONVERTER 500 uses the latest advances in inverter technology, which brings a number of benefits for the user. First of all, the machine is much smaller and lighter (27 kg) than traditional transformer welders of similar power. This is a major advantage for mobility: you can easily move the welder to the workstation, even to places that are hard to reach.
Another key advantage of inverter technology is high energy efficiency (86%) and a power factor close to unity (0.9 cos φ). This means lower power consumption for the same amount of work, which results in lower operating costs and less load on the supply network. For a professional who uses welding equipment intensively, these savings can be significant over a year. In addition, the stable, precisely controlled output current gives higher weld quality and less spatter, which cuts the time needed for finishing.

Key Features and Benefits
- Powerful Inverter Technology: At the heart of the machine is an advanced inverter circuit that delivers an impressive welding current of up to 450A while keeping compact dimensions and a relatively low weight (27 kg), and also ensures excellent arc stability and high energy efficiency (86%). For a professional this means welding thick materials at high speed, easier transport to the job site and lower electricity bills compared with traditional transformer welders.
- Advanced Arc Assist Functions (Arc Force, Hot Start, Anti-Stick): The CONVERTER 500 has an integrated package of functions that make MMA welding much easier. Hot Start briefly raises the current at the start of welding, which makes arc striking easier even with difficult electrodes or contaminated surfaces. Arc Force dynamically regulates the short-circuit current, prevents the arc from going out and makes it easier to control, especially with a short arc and in out-of-position welding. Anti-Stick automatically reduces the current if the electrode sticks, protects it from overheating and lets you free it easily. The result is smoother work, fewer interruptions and higher weld quality from the very start.
- Welding Versatility: MMA and TIG LIFT: The machine not only offers excellent parameters for welding with coated electrodes (MMA) across a broad diameter range (1.6 - 8.0 mm), but also allows precise TIG welding with LIFT contact ignition. This function is ideal for welding stainless steel, copper and titanium, where high weld quality and appearance are required, without the risk of tungsten contamination, which is essential in many industrial and craft applications.
- Reliability and Safety in Harsh Conditions: The TELWIN CONVERTER 500 welder is designed for intensive use in demanding industrial environments. The solid construction, IP23 protection rating and numerous protection functions (thermal, overvoltage, undervoltage, overload, generator +/-15%) ensure a long service life and operator safety. The high duty cycle (e.g. 350A at 60%) allows long welding runs without worrying about overheating.
- Intuitive Operation and Precise Adjustment: Despite its advanced functions, the welder is simple and intuitive to operate. The clear control panel with a precise potentiometer allows smooth adjustment of the welding current to suit the task and the electrode type. This saves time and ensures optimal settings, even for less experienced operators, who will quickly appreciate how easy it is to set up.
- Optimised for Power Generators: Thanks to advanced electronics and protection features, the CONVERTER 500 can work efficiently with power generators (with a voltage fluctuation tolerance of +/- 15%). This greatly increases mobility and the scope for use in the field, on construction sites and in places without access to a stable power grid, which is invaluable for companies doing installation and service work at different locations.
