VEVOR MIG-270 3-in-1 Welder: MIG, Lift TIG and Stick specs explained

The VEVOR MIG-270 is a multi-process inverter welder that combines MIG, Lift TIG and stick (MMA) welding in one portable unit. It runs on either 110 V or 220 V and is described by VEVOR as an entry-level machine for outdoor repairs, farm and road equipment, and general maintenance.

Three processes in one machine

• MIG: a wire electrode feeds continuously through the torch, with shielding gas or flux-cored wire protecting the weld. It is generally the quickest process to learn.
• Lift TIG: you touch the tungsten electrode to the work and lift it to start the arc, with argon shielding the weld. It gives fine control on thin material but takes practice.
• MMA (stick): a flux-coated electrode is consumed as you weld. It copes well with rust, wind and outdoor conditions.

VEVOR says the machine suits carbon steel, iron and stainless steel. It states plainly that this welder cannot weld aluminium.

Wire and feed

The MIG side takes 0.6, 0.8 and 1.0 mm (0.024, 0.031 and 0.039 inch) wire, solid or flux-cored, on 2.2 lb or 11 lb spools. Flux-cored wire makes it possible to weld without a gas bottle, which is handy outdoors, though solid wire with shielding gas typically gives a cleaner finish. Wire speed is adjustable from 2.2 to 12 m/min.

Power and current

The specification gives a current range of 50-220 A and a rated input of 5.6 kVA, on 110 V or 220 V. Knobs adjust current, voltage and wire speed, and an LCD shows the settings. Welding output depends on supply voltage: on a 110 V outlet, a welder typically delivers less current than on 220 V, so thicker steel generally needs the higher voltage. Check the manual for the duty cycle at each setting.

Inverter technology

IGBT inverter design is what keeps the unit small and light, compared with older transformer welders. VEVOR says it gives a stable arc. The unit has overheat and overload protection that shuts it down automatically, and an IP21S protection level, which is not weatherproof. Keep it dry.

Size

VEVOR lists the weight in different places (30 lb for the shipping weight, 21.7 lb for the machine itself) and the unit has a carry handle. The listing gives item dimensions of 20.4 x 12.2 x 15.0 in.

What's included

The package has a 3 m gas-shielded MIG torch, a 5 m argon arc (TIG) torch, an electrode holder cable, a 2 m earth clamp cable, a 2 m argon tube, a slag hammer, a 1 kg spool of 1.0 mm carbon steel wire, welding glasses with a brush, and the manual. A welding helmet, gloves and a gas regulator aren't listed, so check what you'll need.

Who it suits

Hobbyists, farm and workshop users, and people learning to weld who want to try more than one process on mild and stainless steel.

What to check before you buy

• Material and thickness: confirm your typical work is steel or stainless, and check the maximum thickness for your supply voltage.
• Power supply: know which outlet and circuit you'll use, and follow local electrical codes and the manual.
• Gas: TIG needs argon, and solid-wire MIG needs shielding gas. Check regulators and fittings.
• Safety gear: a proper auto-darkening helmet, gloves and ventilation are essential.
• Consumables: contact tips, nozzles and wire spools wear out.

The short version

• A 3-in-1 inverter welder: MIG, Lift TIG and MMA.
• 110 V / 220 V input, 50-220 A range, 0.6-1.0 mm wire.
• LCD display with adjustable current, voltage and wire speed.
• Overheat protection; not for aluminium.
