Technical Features

  • Multiprocess MIG/MAG, TIG and MMA capability on one power source, allowing you to cover most bodyshop and fabrication welding tasks from thin automotive panels through to heavier structural work.
  • Watercooled configuration using the FK 5000 cooling unit, keeping the torch and power source temperature under control on sustained highamperage work and improving consumable life in production environments.
  • Compact 350 A power source with integrated wire feeder and lightweight hose pack, giving good manoeuvrability around vehicles and jigs while still offering industrialduty output.
  • Gascooled or watercooled options in the same platform, so workshops can match cooling setup to their typical duty cycle and torch preference without changing machine family.
  • Synergic MIG/MAG programmes for steel and other common wires, simplifying setup by automatically matching voltage and amperage to wire diameter and gas selection once the basic job parameters are chosen.
  • STEEL, STEEL ROOT and STEEL DYNAMIC arc characteristics, allowing you to switch between universal welding, strong gapbridging root runs and a harder, more concentrated arc for high travel speeds and deep penetration.
  • Spot welding mode for placing repeatable tack welds at defined intervals, useful for panel alignment and fixture work where consistent spot spacing matters.
  • Stitch (interval) welding mode for producing a rippled seam appearance with reduced heat input, helping to minimise distortion on thin body panels and lightgauge sections.
  • Selectable operating modes including 2T, special 2T, 4T and special 4T, giving better trigger control on longer welds, positional work and when you need to reduce operator fatigue.
  • Clear digital control panel with process selection and characteristic number display, making it straightforward to recall proven job settings and standardise procedures across multiple welders.
  • Comfort Wire feederinching function, allowing the machine to automatically draw the wire into the feeder without opening the wirefeed unit, speeding up wire changes and reducing the chance of feeding errors.
  • Compact separate wire feeder design with Fronius System Connector, keeping the torch and feeder assembly neat and reducing the chance of snagging when working around vehicles or inside frameworks.
  • High wire feed speed capability (up to around 25 m/min on suitable models), enabling high deposition rates when running larger diameter steel wires on heavier fabrication jobs.
  • Optional water chiller integration for stable cooling water temperature, improving reproducibility on long continuous welds and hightemperature applications.
  • Builtin support for different wire spool sizes, letting you choose between smaller spools for mobile work and larger spools for production to reduce changeover time.
  • Spot and interval welding functions available across processes, allowing flexible use in both repair and light fabrication without needing additional controllers.
  • Robust industrial construction intended for continuous use, making the unit suitable as a workshop “workhorse” for dayin, dayout welding rather than occasional lightduty use.
  • Good duty cycle at 350 A (40% range), giving practical sustained output for thicker sections, chassis work and heavy brackets without frequent thermal cutout.
  • Watercooled torch capability in the package, improving operator comfort and reducing torch handle temperature during long fillet welds and highcurrent spray transfer work.
  • Compatibility with genuine Fronius accessories and torches, ensuring reliable wire feeding, correct connector interfaces and consistent results in professional bodyshop environments.

FAQs

Is the Fronius TransSteel 3500c water cooled package suitable for professional workshop and bodyshop use?
Yes. The TransSteel 3500c is a 3‑phase, 400 V compact multi‑process MIG/MAG inverter with up to 350 A output at around 40% duty cycle, designed for continuous industrial welding on steel and other common workshop materials. The water‑cooled package is well suited to high duty, multi‑shift environments such as bodyshops, fabrication shops and repair centres where longer weld runs and higher currents are common, as the cooling keeps torch and cables stable and improves consumable life.
What is typically included in the TransSteel 3500c water cooled package?
Most 3500c water‑cooled packages include the compact 3500c power source, 3‑phase input leads, 4‑roller wire feed system, FK5000 or equivalent water cooling unit pre‑filled with Fronius FCL coolant, a water‑cooled MIG torch, and a set of drive rolls for common wire diameters. Exact contents can vary by supplier, so BWS engineers will confirm whether you need additional torches, interconnections, or specific rollers and will configure the package to suit your wire sizes and typical jobs.
What power supply and installation requirements does the TransSteel 3500c have?
The TransSteel 3500c runs on 3‑phase, typically 380–460 V in European and UK workshops, with a welding current range from 10 to 350 A. It is a compact unit with approximate dimensions of 747 x 300 x 497 mm and weight around 36 kg, so it can be trolley‑mounted with a cooler and cylinder for mobile use around the workshop. For correct installation you should provide a suitably rated 3‑phase supply, appropriate fusing and cabling, and ensure adequate ventilation and access for service; BWS can advise on supply sizing and site layout.
What materials and processes can the TransSteel 3500c water cooled package handle, and what about consumables?
The 3500c is a multi‑process MIG/MAG system capable of welding steel and stainless with solid and flux‑cored wires, and can also be set up for other wires such as CuSi for bodyshop panel repairs. With the correct torch and wire it can support MIG brazing and other processes used in modern automotive and fabrication work. The machine uses a 4‑roller drive for reliable feeding across 1.0–1.2 mm wires commonly used in structural and production welding. Torches are typically Euro‑connector type, so standard Binzel‑pattern consumables are compatible; BWS can supply genuine Fronius torches, liners, rollers and spare parts, as well as the recommended Fronius FCL coolant for the water unit.
