Ease of Use

Whether you’re a novice or an old timer welder, you’ll find it very easy operating this machine. It comes with everything ready for you to start welding and the unit has a color LCD display to guide you through the easy setup process.

The Auto-Set Elite feature allows you to quickly and easily set weld parameters for the material type and thickness that you’re working on. You can easily fine-tune these parameters to match your specific application. When you’re setting up the system, this function will ask you the following criteria: the welding process you’ll be using, material thickness and the diameter of the wire, rod or tungsten. Then, based on these criteria it will automatically determine weld parameters.

On the side door of the unit, you will also find a guide sheet to help you with setup and configuration. However, considering that the digital interface can also walk you through the easy setup process, you might not even need to use it.

On either side of the display, there are also knobs for adjusting the volts and wire feed speed to your particular needs. The auto-set elite function just puts you in the range and then using the knobs you can tweak the settings until you reach the sweet spot.

The welder also offers easy switching between the different welding processes. The auto spool gun detects feature automatically detects if you’ve connected a MIG gun or a spool gun. There are also two different gas inputs for TIG and MIG, so you don’t need to change the tanks every time you’re making the switch.

Quick Select Drive Roll

Smooth Start

The machine has a smooth start feature, which is the run at the speed of the drive motor. It means that the motor starts the operation at a slower speed and then ramps it up to normal speed. This helps to create a smoother arc with less spatter and eliminates popping starts.


Miller Multimatic 215 can run on 120V and 240V. To switch from one power input to another, you don’t need to use any tools for configuration. The multi-voltage plug allows making the switch just by choosing an appropriate plug for the receptacle and connecting the power cord.

It can weld up to ⅜” mild steel. The machine can also weld stainless steel and aluminum. However, this model doesn’t TIG weld aluminum, as it is DC only. For this, you will need to use MIG welding, which will require additionally purchasing a spool gun.



This unit uses inverter technology, which allows combining high power performance and portability with just 38 pounds weight.


There is a cooling system for the power source, which runs only when needed. This helps to reduce noise, make the system more energy efficient, and reduces the number of contaminants that get pulled through the unit.
