The manufacturer iWave 190i–500i — TIG DC and AC/DC welding power source 3–500 A

Country: Austria · Model: iWave 190i / 230i / 300i / 400i / 500i

The industrial iWave source for TIG argon-arc welding with direct and alternating current is made for 190, 230, 300, 400 and 500 A, with a lower current limit of 3 A. It is used for critical visible welds on stainless steel, aluminium and other metals in food and chemical machinery and on pipelines.

Description

The 190i comes only as AC/DC, the 230i in DC and AC/DC versions, and the 300i, 400i and 500i also in two variants. The smaller 190i and 230i run on a single-phase 230 V supply or, in the multivoltage version, 120–230 V; the larger ones on three-phase 400 V or in the 200–600 V range. The 190i torch is gas-cooled; the other models come with gas or water cooling. CycleTIG delivers current in short intervals, which makes it easier to control the pool on very thin metal, reduces heat tint and prevents burn-through on fillet and butt welds. RPI auto starts the arc quickly and repeatably regardless of surface condition, and the ignition delay is reduced by up to 71 %, according to the manufacturer. The menu with graphics and text in more than 30 languages is operated with a touch screen or a knob, including with gloves on. Wi-Fi, Bluetooth and NFC are fitted to all models for the wireless RC Pedal TIG, the RC Panel Basic remote, the Vizor Connect mask and software updates, while the 300i–500i also have Ethernet and SpeedNet as standard.

How to choose

The first question is whether alternating current is needed. For aluminium AC/DC is chosen; for steel and stainless steel DC is enough. Next, mains supply and current are decided: 190i and 230i for single-phase supply and thin metal, 300i–500i for a three-phase workshop and thicker parts. Only the larger 300i–500i with the Multiprocess PRO option add MIG/MAG with all welding packages, so one source replaces a TIG station and a semi-automatic machine. TIG and MIG/MAG parameters are calculated by the WeldConnect app.

FAQ

What is the minimum welding current of the iWave?

All models start at 3 A, so very thin metal can be welded. The upper limit is 190, 230, 300, 400 or 500 A depending on the model.

Does the iWave 230i work from a single-phase supply?

Yes, the 190i and 230i run on 1×230 V, and the multivoltage version accepts 120–230 V. The 300i–500i models need a 3×400 V supply or the 200–600 V version.

What is CycleTIG in the iWave?

Arc control based on the principle of intermittent welding in short intervals. It makes pool control easier on thin metal, reduces heat tint and prevents burn-through.

Can the iWave be used for MIG/MAG semi-automatic welding?

Yes, but only on the 300i, 400i and 500i with the Multiprocess PRO option. The smaller 190i and 230i support TIG and MMA.
