The EWM Phoenix 330 is an inverter multiprocess power source of modular build, handling MIG/MAG, TIG and MMA. In MIG/MAG you set the current from 5 to 330 A, at a 40% duty cycle the machine holds 330 A, at 60% it gives 290 A, and in continuous work 230 A. You run the parameters from the Progress panel with a list of JOB programs and a digital read out.
What this machine is for
The Phoenix 330 is a source for bays that work on a mixed range of parts. The microprocessor control reacts to changes in the arc at once, which limits spatter and shortens the work after welding. The wire feed speed runs from 0.5 to 24 m/min, so with it you handle thin sheet at a low feed and efficient welding of thicker sections at a high one. The modular build means you join the source with a separate wire feeder and an interconnection cable, and you extend the bay with a liquid cooler. Such a layout has two advantages in production: you leave the power unit in one place and the light feeder travels after the welder, and you convert the same set for another process by changing only a module, not the whole machine. With the MIG/MAG method you weld with solid wire in a gas shield, in TIG with a non consumable electrode, and in MMA with a covered electrode, so one bay covers most of the typical jobs of a structural workshop.
The maker pointed to work such as production of heavy farm and construction machines, welding of pressure vessels under quality supervision, building of bridge structures and steel halls, reclamation of parts in the mining industry, tight welds in the chemical and food industry, components for wind power and metalwork shops working on stainless steel. That list shows the class of the machine well: heavy industry, pipelines, steel structures and technical service.
A separate advantage of this construction is work with long cable packages. The voltage drop compensation circuits hold the arc parameters with a package up to 40 m long, so you put the feeder far from the source, on another level of the shop or inside a large structure. In assembly of tanks and in work at height this saves carrying equipment about. The maker optimised the forceArc and rootArc processes for unalloyed and low alloy steels, that is for the typical structural material, and there they make the biggest difference in the number of layers and in the working time.
Features and equipment
- MIG/MAG, TIG and MMA processes in one source: you convert the bay without changing the machine.
- Current range from 5 to 330 A with duty cycles of 330 A at 40%, 290 A at 60% and 230 A at 100%: reserve for thick welds and a current for continuous work.
- Wire feed speed from 0.5 to 24 m/min: handling of thin sheet and efficient welding of thicker material.
- Progress panel with JOB lists: once you point to the material, the gas and the wire diameter, the machine picks the voltage and the feed itself.
- Digital displays of current and voltage: you see the real values during welding, which makes work under technical supervision easier.
- Storage of your own settings: it shortens the changeover when the range of parts changes.
- forceArc: a narrowed, concentrated arc with a high pressure gives deep penetration and lets you reduce the bevel angle, so you use less filler.
- rootArc: a stable short arc for root layers, with good bridging of gaps.
- Pulse welding: it takes away almost all the spatter, which cuts the cost of the work after welding.
- SuperPuls: laying two different pulse currents over each other gives an effect close to a TIG bead and keeps the amount of heat in check on thin materials and on stainless steel and aluminium.
- Thermostatically controlled fans: they start only when needed, so the machine draws in less dust and is quieter.
- Cooling ducts that separate the electronics from dirt: a circuit prepared for work in a dusty shop.
- Voltage drop compensation: a stable arc with a cable package up to 40 m long.
- Modular build: you extend the source with a liquid cooler and with different variants of wire feeders.

What to watch out for
The supply is 3 x 400 V with a tolerance from minus 25 to plus 20 percent, the protection class is IP23, the insulation class is H. The weight without the feeder is about 45 kg and that is how you have to read this figure: it is the power unit alone. For welding with wire you need a separate feeder and an interconnection cable, and for a liquid cooled torch also a cooler. The product data sheet gives gas cooling of the torch, so on long welds at a high current watch the load capacity of the torch.
The duty cycle at 330 A is 40%, for work without breaks 230 A is left and you plan the output of the bay to that figure. The maker optimised the forceArc and rootArc processes mainly for unalloyed and low alloy steels, on other materials the benefit is smaller. Both technologies need the torch to be led evenly, otherwise you will not use their advantages. An inverter takes extreme dust badly, so the inlet grilles have to be cleaned regularly. The Progress panel gives a lot of functions and at the first start it needs a walk through the JOB lists, so that the operator knows where to look for the settings. With a long cable package check the state of the insulation and of the connectors along the whole length, because that is where the resistance usually grows and the arc voltage drops.
