It’s part of Fronius’s TPS/i platform, which can run advanced welding packages such as Pulse, LSC, PMC and CMT depending on the software installed. This complete water-cooled package comes ready to weld. It includes the TPS 500i power source, Fronius water cooler, Fronius wire feeder, a 10 m interconnecting cable, a Binzel MB501 4 m water-cooled torch with Euro adaptor, a 10 m power lead with 3-phase plug fitted, an earth lead, an argon regulator and a gas hose. This unit has been [inspected and tested by the QWS workshop, confirm] and is covered by a 3-month QWS warranty.
Fronius TPS/i performance at a used price
The TPS/i is Fronius’s flagship intelligent welding platform, used in heavy fabrication, structural steel, shipbuilding, mining, pressure work and automotive manufacturing worldwide. The TPS 500i combines high output with precise digital arc control. Its 100% duty cycle at 360A suits long production runs on thick plate, and the water-cooled torch keeps the operator comfortable at high amps. A new Fronius system is a major investment. This used package gets you Austrian-engineered TPS/i performance for much less, from a specialist distributor that has tested it before sale.

Frequently asked questions
What is the Fronius TPS 500i?
It’s a 500-amp, 400V three-phase MIG/MAG welding power source from Fronius’s TPS/i range, their flagship intelligent welding platform. It’s designed for heavy-duty manual and production welding, with digital arc control and optional advanced welding packages.
What’s the duty cycle of the TPS 500i?
At 40°C it delivers 500A at 40%, 430A at 60% and 360A at 100% duty cycle. That makes it suitable for continuous production welding.
What welding software does this used TPS 500i have?
This unit has [confirm]. TPS/i power sources use licensed welding packages that unlock different processes. Standard covers conventional MIG/MAG. Pulse adds pulsed MIG. LSC gives low-spatter short arc. PMC is advanced pulse control. CMT is cold metal transfer for very low heat input. Contact QWS if you’d like to add or upgrade welding packages.
What power supply does the TPS 500i need?
It runs on 400V three-phase power with 35A slow-blow fuse protection. This package comes with a 10 m power lead and a 3-phase plug fitted. Have a licensed electrician confirm your supply suits the machine.
Why does this package use a Euro adaptor?
Fronius TPS/i wire feeders use Fronius’s own torch connection. The Euro adaptor lets you use standard Euro-connection torches such as the supplied Binzel MB501, so replacement torches and consumables are widely available and lower cost.
Why water-cooled?
At high amps over long runs, an air-cooled torch gets hot and its consumables wear quickly. The Fronius water cooler and Binzel MB501 water-cooled torch keep the torch cool, extend consumable life and make full-shift welding at high output more comfortable.
What warranty comes with this used Fronius package?
QWS covers this used TPS 500i package with a 3-month warranty.
Can I finance a used Fronius welder through QWS?
Yes. QWS offers equipment finance, including lease-to-own options. Contact the sales team to discuss.
