Fronius TPS 4000 is an industrial MIG/MAG power source with synergy and pulse. You set the current from 3 to 400 A, at a 100% duty cycle the machine gives 250 A, and the power source itself weighs 37 kg.
What this machine is for
The power source works in workshops and on production lines, where the same settings have to come back on every shift. The range from 3 to 400 A covers thin sheet and thicker structural joints. The load rating is 400 A at a 35% duty cycle, 350 A at 60% and 250 A at 100%, so plan continuous work up to 250 A and keep the higher currents for shorter passes.
In synergic mode you point to the material, the wire diameter and the shielding gas, and the machine sets the rest of the parameters, so you make fewer mistakes when the job changes. Pulse limits spatter and puts the heat input in order, so you run aluminium and stainless steel more easily. You adjust the arc dynamics separately and match it to the position and the material thickness.
Features and equipment
- Synergic mode: after you point to the material, the wire diameter and the gas, the system sets the parameters itself.
- Pulsed welding, it limits spatter and puts the joining of aluminium and stainless steel in order.
- Arc dynamics adjustment for the material and the welding position.
- Special four stroke mode with current up slope and down slope.
- Spot and stitch welding with limited heat input.
- A clear panel with storage of welding programs.

What to watch out for
The supply is 3 x 400 V, the open circuit voltage is 70 V, and the housing measures 625 x 290 x 480 mm at a weight of 37 kg, so you will move the power source itself in a car. The product record gives liquid cooling, while the description lists neither a cooling unit nor a wire feeder, so you put both parts together separately along with the cable package and that has to be settled before you buy. You get 400 A at a 35% duty cycle, and in continuous work stay at 250 A, otherwise the thermal cut out will act.
The old description carried the story of the previous owner with a claim that plant output rose by 30% after the power source was changed. That is a user opinion and not a parameter of the machine, so treat it the same as any opinion. With a liquid cooled torch check the coolant level and the circuit before the start.
