Used UNIMIG ENVY MULTI 230 AC/DC Multi-Process Welder
UNIMIG Part No. U11203 | QWS SKU [confirm] | Used, great condition, workshop tested
The UNIMIG ENVY MULTI 230 AC/DC is a professional 230-amp, 240V multi-process welder. One machine does MIG, AC/DC TIG and stick. It has single and double pulse MIG, high-frequency AC and DC TIG with pulse up to 999 Hz, Mixed AC/DC for aluminium, and MIG and TIG Smart-Set synergic programs. It welds mild steel, stainless, aluminium, copper, silicon bronze and titanium. This used unit is in great condition, has been tested by the QWS workshop, and comes ready to weld with MIG torch, TIG torch, electrode holder, earth lead and argon regulator. It’s covered by a 3-month QWS warranty.
Every process in one machine, at a used price
The ENVY MULTI 230 suits fabricators, repair shops, farms and serious home workshops that need to MIG steel, TIG aluminium and run stick from a single 240V machine. You don’t need two or three separate welders. Because it does AC TIG as well, it covers aluminium boat, trailer and ute tray work as well as steel fabrication. Buying this unit used gets you all of that for well under the new price, from a specialist distributor that has tested it before sale.
Key features
- True multi-process, all in one: MIG, flux-core, HF AC/DC TIG, lift TIG and stick (MMA).
- Single and double pulse MIG. Better control of heat input and a TIG-like bead finish on aluminium and stainless.
- MIG and TIG Smart-Set. Enter the material, wire or tungsten, and thickness, and the machine sets synergic starting parameters.
- High-frequency AC/DC TIG with pulse up to 999 Hz. Tight arc control on thin and heat-sensitive metals.
- Mixed AC/DC. Combines AC cleaning with DC penetration for faster, deeper welds on aluminium.
- Independent AC amplitude. Set amperage separately for the EP and EN halves of the AC cycle, to control heat on the workpiece and the tungsten.
- Takes 1 kg and 5 kg spools. Use small spools for aluminium or stainless, or larger spools for production steel.
- 240V single phase. Plugs into a standard 15A outlet.
- Generator compatible. Runs from a generator of 10 kVA or more.

Frequently asked questions
What processes can the UNIMIG ENVY MULTI 230 AC/DC do?
It does gas MIG (including single and double pulse), gasless flux-core, high-frequency AC and DC TIG, lift TIG and stick (MMA). That covers steel, stainless and aluminium with one machine.
Can the ENVY MULTI 230 weld aluminium?
Yes, in two ways. You can pulse-MIG aluminium with the included M26 torch (a spool gun or teflon liner setup is recommended for best feeding), or TIG it in AC mode using Mixed AC/DC and independent amplitude control.
What’s the difference between the ENVY MULTI 230 and the ENVY TIG 230?
The ENVY MULTI 230 adds MIG (including pulse and double pulse) to AC/DC TIG and stick, so it’s the more versatile all-rounder. The ENVY TIG 230 is a dedicated TIG and stick machine for welders who don’t need MIG.
What power supply does it need?
It runs on 240V single phase and UNIMIG recommends a 15A outlet. For generator use, choose a unit of at least 10 kVA with clean, stable output.
What wire sizes does it take?
0.6–1.2 mm wire on 1 kg (100 mm) or 5 kg (200 mm) spools.
What thickness can it weld?
Up to 10 mm in MIG and TIG modes, and 2–12 mm in stick mode, depending on joint preparation and the number of passes.
What warranty comes with this used welder?
QWS covers this used ENVY MULTI 230 with a 3-month warranty. It has been workshop tested and is in great condition.
Can I finance a used welder through QWS?
Yes. QWS offers equipment finance, including lease-to-own options. Contact the sales team to discuss.
