Fronius TPS 4000 – MIG/MAG welder for the discerning user

The Fronius TPS 4000 is a professional MIG/MAG welder that provides precision welding through synergy and pulse technology. The device is designed for the highest weld quality and process stability. Thanks to its modern solutions, it is suitable for both workshops and production facilities.

Key features and technologies

• Synergy – Automatically adjusts welding parameters to the material, wire diameter and shielding gas type. This solution streamlines setup and eliminates user errors.
• Pulsed welding – Significantly reduces spatter, improving weld quality and enabling precise joining of aluminum and stainless steel.
• Advanced arc control – The ability to adjust arc dynamics allows you to tailor the process to your specific welding needs.
• 4-bar special mode – Makes it easier to control the process by gradually increasing and decreasing the current.
• Spot and multi-pass welding – Allows precise joining of parts with minimal heat effects on the material.
• Easy-to-read control panel – Intuitive interface makes it easy to change parameters and save welding programs.

Previous owner’s history

Marek ran a metal fabrication shop and struggled with unstable welding machines that did not provide repeatable results. Frequent chipping and the need for corrections prolonged the production process and increased costs. Everything changed when he decided on a Fronius TPS 4000.

Thanks to synergistic technology, the device automatically adjusted welding parameters, saving time and improving weld quality. Pulsed welding significantly reduced spatters, eliminating the need for additional machining. As a result, the productivity of his plant increased by 30%, and the quality of the welds attracted new customers. After years of use, Marek decided to expand his business and invest in a new Fronius model, and left the TPS 4000 in excellent condition for another professional.
