AZZUNO 135A MIG Welder 3-in-1 - Portable Flux Core, TIG & Stick

In this review the AZZUNO 135A is presented as a compact, affordable multi-process welder aimed at hobbyists and light pros who need portability without sacrificing basic capability. The main reason to buy is its 3-in-1 function: gasless Flux Core MIG, lift TIG capability and stick welding in one 9 lb unit, which makes it a practical choice for home repairs, mobile jobs, and small fabrications where a full-size shop machine would be overkill.

Key Features

• 3-in-1 welding modes: Combines Flux Core MIG, Lift TIG and stick welding so the user can switch between common welding tasks without multiple machines.
• 135A maximum output: Provides enough power to weld mild steel up to about 5/32 in thick, suitable for many DIY and light professional repairs.
• Smart SYNERGIC control: Automatically matches voltage and current to the selected wire size, reducing setup guesswork for novice operators.
• Compact and portable: At about 9 lb and small chassis dimensions it is easy to carry to jobs, store in tight spaces, and use for mobile welding work.
• Included accessories: Ships with an auto darkening helmet, flux-cored wire, electrode holder, ground clamp and spare helmet lenses, so users can start welding right away.
• Safety protection system: Built-in overheat protection and a high-efficiency cooling fan help prevent damage during extended or heavy use.

Who It's For

This unit is best for home DIYers, farm and garden repair tasks, light fabrication, and mobile technicians who need a single lightweight machine that covers multiple weld types. The gasless Flux Core MIG is particularly convenient where shielding gas is impractical or portability is required.

It is less suited for heavy industrial production or fabricators who require high duty cycle, continuous high-amp TIG with a dedicated TIG torch (the TIG torch is not included). Users needing deep-penetration, high-precision TIG in a shop environment should consider a dedicated TIG power source.

Pros & Cons

Pros

• Versatile 3-in-1 operation covers flux-cored MIG, lift TIG and stick welding without buying multiple machines.
• Lightweight and portable design makes it easy to carry to remote jobs and use in tight spaces.
• SYNERGIC control and smooth wire feed simplify setup for beginners and speed work for experienced users.
• Good value with useful accessories included, such as an auto darkening helmet and spare lenses.

Cons

• Not intended for heavy industrial use; duty cycle and continuous high-amp performance are limited compared with larger machines.
• The TIG torch is not included, so buyers who want full TIG capability must purchase that torch separately.

Our Verdict

The AZZUNO 135A is a smart choice for hobbyists and mobile welders who need a lightweight, affordable multi-process machine that covers common tasks with minimal setup. Its SYNERGIC control, included helmet and accessories deliver strong value, but those needing heavy-duty continuous welding or a complete TIG setup should look at larger dedicated machines.

Frequently Asked Questions

Does it require shielding gas for MIG?
It supports gasless flux-cored MIG operation, so shielding gas is not required for the provided flux-cored setup.

Is a TIG torch included?
The welder supports lift TIG but the TIG torch is not included and must be purchased separately for full TIG work.

Can it handle thicker steel panels?
With 135A output it can handle steel up to about 5/32 in; thicker material will need a higher-amp machine.
