The Ess Pulsarc 550 is a transformer MIG/MAG welder with pulse and synergy, cooled with liquid and run from a 400 V supply. It gives 550 A at a 60% duty cycle and 500 A at 100%, so you run continuous work up to 500 A. The set holds a new torch 4 m long for 500 A.
What this machine is for
This is a power source for heavy production and long welds on thick sections. 500 A at a 100% duty cycle means welding without breaks, and the reserve up to 550 A you take on thick fillet welds. Liquid cooling keeps the torch in check at such currents.
Pulse detaches the drops without a short circuit, so there is less spatter. Synergy with programs for different metals shortens the changeover, because you pick the material and the wire diameter, and the circuit sets the rest. The interconnection cable 5 m long moves the feeder away from the source.
Features and equipment
- Pulse: the drops detach without a short circuit, so there is less spatter.
- Synergy: parameters from curves instead of hunting for the working point by hand.
- Programs for welding different metals: ready parameter lines.
- Liquid cooling: the fluid circuit takes heat off the torch at currents of the order of 500 A.
- Transformer build: a construction resistant to dust and to voltage swings.

What to watch out for
The torch from the set is made for 500 A, and the source gives up to 550 A, so at the highest settings pick a torch for that current. The length of the earth cable is not given, ask about it before you buy. The 400 V supply needs a power socket, and a transformer source pulls more from the mains than an inverter. Liquid cooling is a separate circuit, in which you check the fluid level. The source description gives neither the list of programs nor the weight, confirm them on collection.
