Power & Output

You can set output from 20 A up to 160 A, which gives you a useful range for thin sheet metal up to light-to-medium gauge steel. The synergy control simplifies matching current with wire feed speed, which is especially helpful when you’re adjusting for different material thicknesses.

Welding Modes

Because it manages four processes—Gas MIG, Gasless (Flux Core) MIG, MMA stick, and Lift TIG—you won’t need separate machines for basic welding tasks. That versatility makes this a convenient single-tool solution for multiple repair and fabrication jobs.

Physical & Accessories

At 4.2 kg it’s very portable, and the package includes essential consumables and accessories so you can get welding almost immediately. You also get both solid and flux core wires preinstalled so you can try both gas and gasless MIG out of the box.

Design and Build

The case is compact and lightweight, prioritizing portability while providing a clear digital display and physical controls for quick adjustments. The yellow finish makes the unit easy to spot in a busy shop or barn.

Portability and Weight

Because it only weighs 4.2 kg, you can carry the machine to remote jobs, or move it around the garage without a second thought. Its compact footprint also saves bench space while leaving room for clamps and other tools.

Torch and Connectors

The European-style torch interface is a plus if you’re used to standard connections or plan to swap accessories. The MIG torch is 2 meters long, giving you a comfortable reach for most workshop and automotive tasks.

Synergic MIG Functionality

You’ll appreciate the synergy feature if you prefer an easier setup: select wire diameter, set your desired current, and the machine auto-recommends a wire feed speed and typical plate thickness. This reduces guesswork and helps you reach a usable arc faster.

Setting Up Synergy Mode

To operate synergy, set the wire diameter and then adjust the current; the machine calculates a compatible wire feed speed. That means you won’t have to manually hunt for the right wire speed while the arc sputters or the wire birdnests in the torch.

How It Helps Beginners

If you’re new to MIG welding, synergy simplifies learning by reducing the number of variables you must manage. You can focus on travel speed and technique rather than constantly tweaking settings.

Welding Modes Breakdown

You’ll want to know how each mode performs and what it’s best suited for. Below is a breakdown of the four modes and what to expect when you use them.

Gas MIG (Solid Wire)

Gas MIG with ER70S-6 yields cleaner welds and lower spatter when you use shielding gas, which makes it ideal for vehicle bodywork and precision projects. The arc is generally more stable than flux core, and penetration can be better when set correctly.

Flux Core (Gasless MIG)

Flux core lets you weld outdoors or in drafty conditions where shielding gas would be blown away. While you’ll see more smoke and slag to clean afterward, it’s extremely convenient for farm repairs and thicker materials where portability and speed matter more than appearance.

MMA/Stick Welding

The MMA mode offers stick welding for thicker or rusty metal where stick electrodes give you better results than MIG. This mode is useful if you need to work on outdoor repairs or thicker steel without gas or when welding positional joints.

Lift TIG

Lift TIG lets you perform TIG-style welds using a lift arc start instead of a high-frequency start, which is safer around sensitive electronics. Expect better weld appearance and precision, useful for thin sheet or stainless steels if you master the technique.

Performance and Welding Results

Real-world performance depends on setup, wire selection, gas, and your technique, but this machine gives you a usable arc and reasonable penetration across its modes. For everyday welding tasks on mild steel, it will handle typical sheet and light structural work well.

Arc Stability and Penetration

When you’re using gas MIG with correct shielding gas and a compatible wire, the arc is stable and penetration is consistent. In flux core mode, penetration can be strong, but you’ll need to manage travel speed and current to avoid excessive bead buildup.

Spatter and Clean-up

Expect lower spatter with gas MIG and more clean-up with flux core and stick. If you prefer minimal grinding, use solid wire with appropriate gas and tune your settings to minimize spatter.

Controls and User Interface

The digital display and voltage control button make it easier for you to get to a usable setting quickly. The interface is designed to be beginner-friendly, with clear feedback on current and recommended parameters.

Digital Display and Buttons

The large digital display clearly shows the current and helps you track changes as you tweak settings, so you won’t be guessing. Buttons and the voltage control knob are easy to reach and respond predictably, which helps when you’re changing settings mid-weld.

Voltage Compensation Feature

The voltage control button compensates for input voltage fluctuations to stabilize the arc. That feature matters if you’re using power from generators or in workshops with variable voltage, because it helps maintain consistent weld quality.

Safety Features

You get built-in protections that help protect the machine and keep you welding longer without unexpected shutoffs. Those protections reduce the risk of permanent damage from overload conditions and help you focus on finishing the job.

Protections

The unit includes overcurrent, overload, overheating, and overvoltage protection, which gives you an added layer of safety during heavy use. These protections will power down the unit or limit output when thresholds are reached, keeping internal components safe.

Thermal Management

The machine uses internal thermal protection and ventilation to prevent overheating during extended welds. Still, you should manage duty cycle expectations and give the unit rest periods during heavy work to extend its life.

Included Accessories and Consumables

You’ll receive a fairly complete kit that helps you start welding right away, with both solid and flux core wire options and essential spare parts. The included contact tips and feed rollers allow you to run either 0.8 or 1.0 mm wires with minimal changes.

What You Get in the Box

The package contains: 1×MIG160 welder machine, 1×MIG torch (2 m), 1×earth clamp, 1×electrode holder, 1×1.0 mm flux cored wire, 1×0.8 mm solid wire, 5×contact tips, 1×0.8/0.9 K wire feed rollers, 1×0.8/1.0 V wire feed rollers, 1×gas hose, 1×brush, and 1×user manual. Those items let you attempt most basic MIG and stick welding immediately and test both gas and gasless MIG workflows.

Useful Extras You Might Need

You’ll likely want a bottle and regulator for shielding gas if you plan to run gas MIG frequently, plus extra contact tips and wires to match the projects you plan. A proper welding cart, extra ground clamps, and a spool gun (if needed for aluminum) are good additions depending on the work you do.

Setup and First Weld

Getting the machine ready is straightforward if you follow the manual: install wire, set rollers, confirm polarity, and check gas flow if using solid wire. The synergy setup cuts down setup time by offering recommended feed speeds once you set wire diameter and current.

Gas Setup for MIG

If you use gas MIG with ER70S-6, attach a standard gas hose and regulator, set flow to the recommended range (often 15–20 L/min depending on nozzle and environment), and confirm there are no leaks. Proper gas setup improves arc stability and reduces spatter.

Wire Installation and Tensioning

Load your spool, ensure the wire path is smooth, set the appropriate drive roller (K or V groove based on wire), and tune wire tension to prevent birdnesting or slipping. Feed the wire through the torch liner and contact tip, then test feed speed with the machine off to confirm smooth delivery.

Wires and Consumables

Understanding the differences between included wires helps you choose the right consumable for the job, and storing extra spools keeps downtime low. Matching contact tip size and roller groove to wire diameter is essential for consistent feeding.

Choosing Solid vs Flux Core

Use solid ER70S-6 with shielding gas when you want cleaner welds and minimal slag; use flux core when you need portability or will be welding outdoors. Flux core typically produces more spatter and slag but gives strong deposition rates in less-than-ideal conditions.

Contact Tips and Rollers

The included 5 contact tips and two sets of rollers let you support the two primary wire diameters without much hassle. Keep spare tips on hand since tips wear with use and can affect arc stability and bead appearance when damaged.

Practical Tips and Best Practices

To get consistent welds, prepare joints properly, choose the right wire/gas combination, and maintain steady travel speed and arc length. Good technique combined with the machine’s synergy settings will yield the best results faster.

Tips for Cleaner MIG Welds

Keep surfaces clean, use a back-step or weave technique for thin sheets to avoid burn-through, and set the correct travel speed to avoid porosity. If you see excessive spatter, check gas flow, polarity, and wire feed consistency.

Tips for Lift TIG and Stick

For Lift TIG, ensure you’re comfortable with a steady hand and practice torch positioning and foot (or fixed) current adjustments if you have them. For stick welding, choose the electrode matching your parent metal and clean the joint area of heavy rust and paint for better penetration.

Maintenance and Longevity

Routine cleaning, checking wire path, replacing worn consumables, and ensuring proper ventilation will extend the life of the machine. Pay attention to the cooling fan and vents, and don’t block airflow during extended use.

Routine Care

Blow out dust periodically, inspect the torch liner and contact tips for wear, and store wires in dry conditions to prevent rust and porosity. Tighten electrical connections and replace worn rollers and tips before they compromise feed quality.

Troubleshooting Common Issues

If your wire birdnests, re-check tension, feed path, and liner condition. If you see inconsistent arc or burnback, verify polarity, contact tip size, and insulate the wire spool from rough movement; consult the manual for error indicators shown on the digital display.
