How to Mig Weld – Tips and Techniques for Beginners

Mig welding is a valuable and versatile process that can be used to join metals of all kinds. The Mig or metal inert gas (MIG) welding process is an arc welding technique that uses an electric current to heat the weld area and a shielding gas to protect it from oxygen in the air, which would cause oxidation of the base material. The MIG process passes an electric current through a wire electrode, which melts when it comes into contact with the Workpiece.

Set Your Welder to the Correct Setting

  • Set your welder to the correct setting.
  • Set the voltage to the right location.
  • Set the wire-feed speed.
  • Set the amperage.
  • Set any contact tips you may want or need for your project. If you are unsure which contact tips are best for your project, consult a professional or ask questions in our welding forums!
  • Make sure that polarity is set correctly for each piece of steel being welded together (this can vary depending on what kind of metal you’re using).
  • Make sure shielding gas is selected if necessary; most people will be fine with just argon gas at this point, but others might have additional requirements based on specific circumstances (e.g., stainless steel requires more expensive gases like helium).

Choose the Correct Wire-feed Speed

To set the wire-feed speed properly, turn on your welder and ensure the transformer is plugged into an outlet. The proper wire-feed rate is vital for good welds, but it’s also necessary for safety reasons. If you aren’t using a dual-frequency welder (which has two separate controls for each function), then there may be only one knob or dial on your machine that controls both operations.

You’ll want to start with a lower setting and gradually increase it until you get the desired result. If you don’t have an adjustable dial or knob on your machine, start by turning up the “high” setting until it becomes hot enough for welding; then turn down the “low” setting until you’re satisfied with its speed.

A common mistake beginners make when trying out different locations is going too fast while still learning how everything works together: if this happens to you as well, then go back over our tips above!

Feed the Gun at a 10º to 15º Angle

After you have positioned the Gun, it is time to move on to the next step: feeding the Gun at a 10º to 15º Angle. This Angle will allow for greater penetration and create a more consistent weld puddle. Again, the welder should be perpendicular to the weld puddle and at an angle that matches up with their Workpiece.

Hold the Gun at a 90º Angle to the Workpiece

It would help if you also held the gun and electrode holder at a 90º angle to the Workpiece. If you do not, you will get a poor weld, as shown in Figures 1-3. This is because when the electrode tip is at an angle to your Workpiece, it causes a poor arc and results in a weak weld.

Keep the Gun at a Constant Distance from the Workpiece

The first thing to remember when starting is to keep the Gun at a constant distance from the Workpiece. This means keeping it at the same height and Angle while moving it forward at a consistent speed. If you’re moving too quickly or slowly, you’ll either burn through your wire or have trouble getting enough heat.

Keep in mind that if you’re working on a large piece of metal (like an engine block), your movements need to be very controlled so that there aren’t any gaps between welds. There might be some overlap between small pieces (like jewelry) between welds; however, this can be fixed with touch-up grinding later in post-processing.

Follow these steps

MIG welding is a great skill to have for many reasons.

To start, it can help you make more money. Welders are in high demand, so they get paid well—you’ll be able to command higher wages than non-welders with similar degrees and experience levels. Moreover, welders typically don’t need college degrees beyond an associate’s degree or certificate program in welding (or related fields).

Additionally, MIG welding offers a lot of job security because there’s always going to be demand for it; after all, we live in an industrial world where everything breaks down at some point and needs fixing!

In this article, we discussed the process of MIG welding and how to do it. We also included some tips for beginners looking to learn how to MIG weld. The basic concept is that you have an electrode that heats up when you run electricity through it, which melts the base metals into a solid bond. This technique can be used for repair work or for creating new pieces from scratch!


MIG Welding is a simple process that anyone with enough practice and patience can master. It’s easy enough to get started right away with the right equipment (e.g., your welder), but there are still some things you need to know before diving in headfirst…such as what kind of material you are working with or what type of metal does not make good contact between electrodes and shielding gases (like argon). Also, make sure everything’s clean before starting work so that no contaminants get mixed into your metal joints!
