MIG Welding Tutorial

The MIG welding tutorial (below) covers the steps you'll need to take to learn how to MIG weld. It's the sort of thing you'd find in a welding for dummies or welding secrets book, but this one includes videos. If you get stuck we have a very friendly forum that can help.

Installing the wire

Wire feed is the most common cause of MIG welding problems. A few tips on how to install the wire and tension the wire feed.

Power and wire speed calculator

A tool to help you estimate initial power settings for your welder. Further pages in the tutorial will help fine tune the settings for that perfect weld.

Torch position and laying welds

Prepping for welding, positioning the torch, and making some practice welds.

Setting the wire speed

MIG welders are sensitive to wire speed. There is a very narrow wire speed range where the welder welds nicely between burn back and stuttering. This page should help you fine tune the wire speed for your welder.

Finding the right power setting

The choice of power setting will vary from welder to welder, and can be influenced by technique. The best way to find the appropriate power setting for your welder is to experiment on scrap metal then examine the welds

Butt welding

It's best to develop neatness and technique before attempting to join two pieces of metal together. It's a tricky first weld, so easier overlap welds are touched upon too.
