Without any delay, let’s get to the review.


Miller Multimatic 220

Miller Electric Manufacturing Company is the world’s largest manufacturer of welding products and is well-known and is highly reputed for its high-quality and feature-rich welding equipment.

The Miller Multimatic 220 AC/DC multi-process welder is not any less that has the capabilities of MIG, TIG, and Stick welding, all packed into a compact and robust 56 lbs. machine.

The AC TIG option that it supports makes aluminum welding more ideal and it might be truly helpful to those welders who do a lot of welding jobs at stores, shops, and DIY projects at home.

Basic Features

Foot Control:

The Multimatic 220 makes it really easy for one to change between the mode of welding and the parameters used with the help of the foot control’. You can leave the MIG gun and torch attached to the machine at the same time and believe it or not, this machine can identify the polarity and welding parameters based on the material you are about to weld on.

Powerful Unit:

The MIG gun provided with the welding equipment can weld steel up to 3/8” (24 gauge) and aluminum of 3/8” (18 gauge) respectively. If you wish to do DC stick welding, it can handle up to 3/8” (16 gauge) stainless steel. It also has the compatibility to do AC/DC TIG welding for welding steels of 24 gauges and aluminum up to ¼” in thicknesses.

Auto-Set Elite:

The ‘Auto-Set Elite’ feature is something no other welding manufacturer might have thought to implement in their welding equipment. It automatically chooses the welding parameters like the voltage, shielding gas, amperage, bead appearance, and more by just analyzing the material and the thickness of the metal used.

Power Input:

This machine supports two voltages of 120V and 240V based on the welding operation and 1-phase voltage. The amperage range is from 30-230 A for MIG, 30-200 for DC stick, and 20-210 A for AC/DC TIG.

Welder Quality:

Miller welders are known for their high-quality welds with precise and well-finished bead performance. It offers a 60% duty cycle at 105A and 19.2V, a 20% duty cycle at 200A and 24V, a 40% duty cycle at 170A, and 21.5V for MIG welding. It offers a 40% duty cycle at 90A and 23.6V and a 15% duty cycle at 200A and 28.4V using Stick welding. If you do TIG welding, then it can offer duty cycles of 20% at 210A and 18.4V and 40% at 130A and at 15.2V.

Installation Process:

The Miller Multimatic 220 is quite easy to set up and use within minutes by a beginner or even a professional welder. There are several tutorials and technique-specific videos available online. You can read their user manuals from ‘’.

Versatile Machine:

Having different techniques of welding like MIG, TIG, stick, and flux-cored welding in a single machine makes a welding professional’s job very easy. This is because he can carry the single machine anywhere he wishes to do welding and that too any type of welding with the trigger of a button.

Auto-Set Elite:

This feature makes any beginner, a professional welder in a few minutes. It identifies and fixes the wire diameter and material thickness to its memory and automatically knows to adjust the wire feed speed and voltage settings. The built-in display also enables the welder to identify the range of each parameter used.

Good frequency range:

The frequency range for this device is from 60Hz to 150Hz which is sufficient enough for and increases the penetration of the weld for most of the scenarios.


The single machine offers a ton of value and features with all of its welding techniques, which makes it quite expensive than other normal welders in the market. Over time, you will get used to it and might find it to be valuable.


The accessories available for this product like the hose, gas cylinders, shielding gas refill, and other utilities must be purchased additionally which might be a bummer for many.


1. What size of wire feed does this welder use for MIG welding?
• The Miller Multimatic 220 AC/DC uses wire of thickness of 0.030 inches for MIG welding.

2. What is the maximum that it is rated for?
• This machine can weld up to a thickness of 3/16 inches for a single pass at 120V. You can use this method to weld thicker metal pieces using multiple passes.

3. How does this machine compare to the ESAB Rebel 205i AC/DC?
• There is much difference in the features that the two devices offer. The Miller products are easily available, in stock for most parts of the year, and have a great customer care service.
