FRONIUS IWAVE 190I AC/DC GAS COOLED
FRONIUS iWAVE 190i AC/DC
TIG AC/DC Inverter Power Source — Gas Cooled
The Fronius iWave 190i AC/DC is a fully digitised, microprocessor-controlled TIG AC/DC inverter built for workshops needing genuine precision on both aluminium and steel from a compact, entry point into the iWave range. It brings the same intelligent ignition and arc control technology found across the larger iWave machines into a smaller, more affordable package — ideal for fabrication, maintenance and general workshop TIG work.
At the heart of the 190i is RPI Auto, Fronius' intelligent ignition function that automatically adjusts ignition settings based on electrode diameter and condition — delivering fast, reproducible arc starts without manual parameter tweaking, and up to 71% less ignition delay compared to running without it.

Why Choose the iWave 190i AC/DC?
Genuine iWave precision at an accessible level. RPI Auto and Active Wave bring the ignition reliability and arc quality of the larger iWave range down into a smaller, workshop-friendly machine.
Confident on aluminium and steel alike. AC/DC output means the 190i handles aluminium and magnesium as capably as it does steel and stainless, without needing a separate machine for each.
Quieter, more stable AC arc. Active Wave technology continuously calculates the optimal waveform, keeping AC TIG welding noticeably quieter without compromising arc stability.
Built for real workshop conditions. A powder-coated housing with protected controls and full generator compatibility mean the 190i holds up to daily use in busy fabrication environments.
Backed for the long run. A 3-year warranty is available simply by registering the machine.
Frequently Asked Questions
What welding processes does the iWave 190i AC/DC support? TIG AC/DC with RPI Auto intelligent ignition, and manual (stick/MMA) electrode welding.
What is RPI Auto? RPI Auto is Fronius' intelligent ignition function, which automatically adjusts ignition parameters based on electrode diameter and condition, delivering fast and reproducible arc starts without manual adjustment — reducing ignition delay by up to 71% compared to running without it.
Can the iWave 190i AC/DC weld aluminium? Yes — the AC/DC output and Active Wave arc technology make it well suited to aluminium, aluminium alloys and magnesium, alongside steel and stainless.
Is the iWave 190i AC/DC gas or water cooled? This model is gas cooled. The larger iWave 230i AC/DC is available in both gas-cooled and water-cooled versions.
Does the iWave 190i AC/DC come with a warranty? Yes — a 3-year warranty applies when the machine is registered.
Is the iWave 190i AC/DC generator compatible? Yes, it's fully generator-compatible, making it suitable for site and remote work as well as workshop use.
