The manufacturer iWave Multiprocess PRO — multiprocess welding power source TIG/plasma/MIG/MAG/MMA 300–500 A

Country: Austria · Model: iWave 300i / 400i / 500i Multiprocess PRO

The Multiprocess PRO configuration combines in the iWave 300i, 400i and 500i sources (DC and AC/DC) TIG with high-frequency ignition, plasma welding, MIG/MAG up to CMT, MMA and CEL cellulosic electrodes. Current for MIG/MAG, TIG and MMA is 3–500 A. Such a source is used where materials and tasks change often, and it replaces several specialized machines.

Models: iWave 300i / 400i / 500i DC and AC/DC with the OPT/i Multiprocess PRO option
Welding current: 3–500 A (MIG/MAG, TIG, MMA)
Processes: TIG (including HF), plasma, MIG/MAG, MMA, CEL
MIG/MAG packages: Standard, Pulse, LSC, PMC, CMT, PMC AC, CMT AC

Description

The changeover to a multiprocess system takes three steps. First the OPT/i Multiprocess PRO hardware option is ordered, then the system is upgraded with MIG/MAG components, that is, an external wire feeder and torches, and finally the welding packages are selected. Standard gives short and spray arc, Pulse works with low spatter, LSC stabilizes the short arc, PMC has penetration and arc length stabilizers, and CMT reduces heat input to a minimum by reversing the wire. AC/DC versions also get PMC AC and CMT AC with polarity change of the wire electrode, useful for thin aluminium. Plasma requires the OPT/i Plasma option, a plasma torch and a plasma welding package, and the universal hose pack is shared by TIG and plasma. The source runs on a three-phase 400 V supply or in the multivoltage 200–600 V version, and for Industry 4.0 it has Wi-Fi, Bluetooth, NFC, Ethernet and SpeedNet.

How to choose

The configuration is chosen by current (300, 400 or 500 A) and the need for alternating current, because AC/DC is required for aluminium and for the PMC AC and CMT AC processes. In the manufacturer's practice, the iWave 400i AC/DC combines CycleTIG and PMC at one workplace. The MIG/MAG wire feeder here is external, for example WF 25i or WF 25i Dual with a speed of up to 25 m/min. When TIG and plasma are not needed and only MIG/MAG up to 600 A is involved, it is more logical to take the TPS/i.

FAQ

Which processes does the iWave with the Multiprocess PRO option support?

TIG with HF ignition, plasma welding, MIG/MAG with packages from Standard to CMT, manual arc MMA and CEL cellulosic electrodes, all in the 3–500 A range.

How can an existing iWave be upgraded for plasma welding?

The OPT/i Plasma option, a plasma torch and a plasma welding package are required. The hose pack is universal, so only the torch body is changed when switching from TIG.

How does PMC AC differ from ordinary PMC?

In PMC AC the polarity of the wire electrode changes, which reduces heat input. This process, like CMT AC, is available only in AC/DC versions and suits thin aluminium.

Is the iWave Multiprocess PRO suitable for additive manufacturing?

Yes, the manufacturer positions the platform for additive manufacturing too, where a part is built up with wire layer by layer.
