AZZUNO 5 in 1 160A Welder Machine, Plasma Cutter Welder Combo with HF TIG/Gas MIG/Flux MIG/Stick Welding, 110/220V Dual Voltage Multiprocess Welding Machine

What I learned using the Azzuno 5‑in‑1

The Azzuno 5‑in‑1 multiprocess unit aims to be a compact answer for small shops and garages that want MIG, TIG, stick, and light plasma cutting without juggling multiple machines. I spent several weeks rotating through all five processes on 120 V and 240 V, cutting and welding mild steel and stainless, and focusing on how quickly I could switch tasks, how predictable the arc is, and what tradeoffs show up when one box does this much.

Setup, build, and interface

Out of the box, the kit is generous: 15AK-style MIG torch, HF TIG torch, plasma torch with consumables, electrode holder, ground clamp, two gas hoses, and an air filter/regulator. There’s also a 120/240 V adapter, which made it easy to test on different circuits. The casework is tidy and the ports are clearly labeled. The cables are better than “budget” grade—flexible insulation and decent strain relief—but the ground clamp is the first thing I’d upgrade if you’re welding anything beyond thin material regularly.

The front panel is a modern digital layout with a synergic mode for MIG. You choose wire diameter and gas, and the machine proposes current and wire speed. You can still trim voltage and feed on the fly, which is important—synergy gets you 90% of the way, but dialing in the last 10% makes the difference between acceptable and excellent. I do wish there were a quick reference chart inside the wire spool door; you’ll lean on your own notes during the first few days.

One practical note: the manual is serviceable but light in places that matter (consumables identification, setup best practices). Expect to supplement it with your own process notes.

MIG and flux‑core performance

On 240 V, running 0.8 mm (0.030 in) ER70S‑6 with C25 gas, the short‑circuit arc is crisp and consistent. Starts are clean with very little stumble, and the puddle wets in nicely. Out‑of‑position fillets on 3 mm and 6 mm mild steel were straightforward. The synergic program gets you very close; trim voltage by ±0.5 V as you shift from lap joints to outside corners to keep the bead profile where you want it.

With 0.9 mm (0.035 in) flux‑core on 120 V, it remains competent for quick repairs and outdoor work. Penetration on 1/8 in steel is no problem. If you often weld thicker material or long beads, plug into 240 V; the machine breathes easier and heat input stabilizes. Wire feeding is smooth and consistent with the included V‑groove rollers for solid wire; plan on a U‑groove roller and a Teflon liner if you intend to experiment with soft wires.

Alauminum MIG is doable in theory, but be realistic: without a dedicated spool gun and the right drive/liner setup, you’ll spend more time tuning than welding. That’s not unique to this unit—just the nature of pushing soft wire through a standard MIG torch.

TIG: clean DC with HF start

HF TIG start is a welcome step above lift‑arc. Non‑contact starts are reliable, and the arc is stable on DC TIG for mild and stainless. I welded 1.6 mm stainless tube and 3 mm plate using a 2% lanthanated tungsten and argon. Heat control is via the torch switch; there’s no pedal in the box, and this machine is DC‑only, so think of it as a precise tool for steels rather than an all‑around TIG station. If your work demands AC TIG on aluminum, you’ll need a different machine.

Gas control is simple, post‑flow is adequate, and the torch is compact enough for tight spots. Again, the manual could do a better job documenting recommended starting points for amperage, tungsten size, and cup selection, but if you’ve TIG’d before, you’ll find your groove quickly.

Stick: forgiving on common rods

For quick repairs or when the wind refuses to cooperate with shielding gas, stick mode is handy. It strikes and runs 7018, 6013, and 308L stainless rods without drama. Like many inverter multiprocess machines, it struggles with cellulose 6010; if you absolutely need to run 6010 to code, this won’t be your primary stick box. Anti‑stick and arc‑force are tuned on the conservative side, which helps beginners but still lets experienced welders carry a tight arc without the rod gluing itself to the work.

Plasma cutting: tidy cuts with realistic limits

The integrated 40 A plasma cutter is better than “bonus-tool” status. On 240 V with a modest shop compressor and dry air through the included regulator, clean cuts on 10 mm mild steel are achievable with a steady hand and consistent standoff. At 12–14 mm, you’re in “get it separated” territory—expect a slower travel speed and more cleanup. Thin sheet and stainless slice cleanly, and the torch consumables are common patterns. Keep an eye on air quality; moisture will quickly degrade cut quality and consumable life, so the included filter/regulator isn’t optional.

Consumables come in the box, but you’ll want to order spares early. A clearer parts list from the manufacturer would reduce guesswork when it’s time to restock tips and electrodes.

Switching processes and workflow

The real advantage here is how quickly you can pivot between tasks. MIG a bracket, TIG a thin tab, slice a slot with plasma, then stick weld outside where gas would be a headache—without re‑wiring your bench. Torch swapping is tool‑less and the UI remembers settings per process, which saves time. Just be mindful of gas line routing and ensure your air is fully bled before switching back to plasma; keeping a tidy cart with quick‑disconnects for gas/air lines pays dividends.

Power, duty cycle, and noise

The machine is happiest on 240 V, as expected. On 120 V, it remains useful for light fabrication, but you’ll hit process limits sooner, especially with MIG on thicker stock or when plasma cutting near the top of its range. I didn’t trip thermal protection during typical runs—tack‑and‑weld sequences, 6–12 inch beads, and intermittent cutting—but if your day includes long continuous beads at higher amperage, a dedicated single‑process machine with a published heavy duty cycle will be more appropriate.

Fan noise is moderate. It’s not whisper‑quiet, but it won’t dominate a small shop unless space is truly tight.

What I’d change

• Documentation: The manual needs clearer consumables part numbers and a setup reference chart. Put a weld parameter cheat‑sheet on the inside door.
• Ground clamp: Works, but upgrading to a heavier clamp improves starts and reduces spatter on higher‑amp stick and MIG.
• 6010 compatibility: Common limitation, but worth stating plainly—plan on 7018/6013 for best results.
• Aluminum expectations: DC TIG only. For AC TIG, look elsewhere; for aluminum MIG, plan on the right rollers/liner and possibly a spool‑gun solution if supported.

Where it shines

• Versatility for the footprint: One box that welds steel well in multiple processes and performs credible plasma cuts.
• Synergic MIG that’s actually helpful: Especially for newer welders or anyone bouncing between materials and thicknesses.
• HF TIG on steels: Clean starts and stable arc for small to medium stainless and mild steel work.
• Value for small shops and mobile repair: Dual voltage, sensible controls, and quick process changes make it a practical daily driver for mixed tasks.

Who it’s for

• DIY fabricators and small garages that need MIG first, with TIG, stick, and plasma as capable backups.
• Maintenance techs who appreciate a compact all‑in‑one for carts or service trucks with access to 240 V power.
• Hobbyists stepping up from a basic flux‑core unit and wanting room to grow without buying three separate machines.

If you primarily do one process at high amperage for long stretches, or you need AC TIG on aluminum or certified 6010 performance, a single‑purpose machine will serve you better.

Recommendation

I recommend the Azzuno 5‑in‑1 to fabricators who value versatility and space savings over specialized extremes. It welds mild and stainless steels cleanly in MIG, flux‑core, TIG, and stick, and its 40 A plasma function is genuinely useful for everyday cutting. The interface is friendly, synergic MIG shortens setup time, and dual‑voltage operation keeps it flexible across shop and field work.

You’ll want to upgrade the ground clamp, build your own quick‑reference chart, and set realistic expectations around aluminum and 6010 rods. With those caveats, it’s an easy machine to live with and a strong value for mixed‑process jobs in a compact footprint.
