LEARN TO WELD: Why Wire-Feed MIG Welders Are The Best Way to Learn

Do you feel the urge to do some welding? I can help you make welding part of your life. I’ve been welding ever since I was in high school in the 1970s, and I can tell you that wire-feed MIG welders make it easier than ever to succeed. A little history makes it easy to see the progress.

In 1982 I was 19 years old and I had the world’s best summer job. Every working day I’d enter the security gates at the back of Canada’s largest theme park – Canada’s Wonderland it’s called – along with hundreds of other high school student employees. But where most of them would turn towards the rides or games or food stands where they worked, I headed in another direction. My job was in the rides maintenance department, working alongside mechanics and electricians who kept the rides running safely. My pay was better than the popcorn jockeys got, but there was an even bigger bonus as far as I was concerned. I was allowed to stay late after my shift and work on metal fabrication projects of my own in the fully equipped metalworking shop. No supervision, no hassles, just hours and hours on my own with industrial-grade tools. My favourite tool at the time was the wire feed MIG welder.

Working outside my shop using a wire-feed welder to join pieces of #9 steel fence wire. Wire-feed welders can successfully joint thin and thick steel.

The letters MIG stand for “metal inert gas” and it’s an amazing welding technology that almost anyone can learn to use well. Back then machines like these were made strictly for industrial use, with a whopping size and price tag to match. But I had that wire feed welder all to myself and I used it to build all kinds of things, including the chrome-and-leather backrest and highway pegs on the 750cc Yamaha Virago motorcycle I was customizing at the time. And while untrained, unsupervised 18-year-old kids probably never get the chance to slip so blatantly past the litigation lawyers and get their hands on powerful equipment these days, something even better has happened for those of us with a passion to create.

Small, affordable wire feed MIG welder tools are now accessible enough for home hobbyists to buy and use successfully. Compact, consumer-grade models retain all the effectiveness of their industrial-grade ancestors. This is what the wire feed welder revolution is all about and it all boils down to a spool of thin metal.

This is the welder I use in my own shop today. Modern wire feed welders are small enough to be portable and affordable enough to be within reach of anyone serious about welding. You can get into the game for less than $500.

One thing that separates wire feed MIG welders from other more difficult-to-use electric welding tools is automatic feeding of the welding wire. Press the trigger on the hand-held gun and a strand of fresh wire extends out the tip. And since this wire is electrically energized, a blue arc jumps from the tip of the wire to the grounded work piece you’re welding. This arc generates heat that melts the wire and the surrounding metal. Move the gun along the seam you’re joining and the melting and deposition continues, using up the wire as it extends out of the gun afresh. Bottom line: a nice, neat weld even if you’re not a professional. Excellent results are embarrassingly easy to create.

This is the motorcycle backrest I made with the wire feed welder in the rides maintenance shop at Canada’s Wonderland in 1982.

Besides ease of use, there are three other unique features of wire feed welders. First, they work exceptionally well on thin metal. Traditional stick-type electric welders can be hard to control in applications like these, making it challenging to join thin metal without burning holes through the material.

Another wire feed welder advantage is the ability to weld aluminum. Better-quality DIY wire-feed welders are designed to allow compressed inert gas to be piped through the gun and out of the welding tip during use. This gas shields the molten weld zone from reacting with oxygen, opening a whole new world of possibilities. The use of shielding gases is called MIG welding (shorthand for “metal inert gas”) an approach that can be used on steel and is also essential for work with aluminum. Even if you don’t expect to be welding anything other than steel, MIG-capable welders create much neater looking welds than models that can’t operate with a shielding gas.

The clean weld on the right was made with a gas-shielded MIG process in a wire-feed welder. The rough weld on the left made with self-shielding welding wire and no gas shielding.

The third amazing feature of wire feed welders is their efficiency. Although large models must be hooked up to special cables, you can do some pretty serious work with wire feed models designed to plug into nothing more than an ordinary wall outlet. Ever get the urge to build an aluminum dock for the cottage? Or how about restoring a vintage automobile? Perhaps a decorative steel fence around your backyard pool is on the list for this year’s home improvement jobs? I use my welder all the time for jobs like these and it’s amazing. A wire-feed welder can help you think of metal in a whole new way. And besides, welding is just plain fun.

I like to keep my online courses relatively small to make sure that everyone gets the support and help they really need. So as much as I like to help everyone, I can only accept a small number of new students right now while still maintaining the level of support that’s needed. Please understand that this is a genuinely rare opportunity, and spots will be granted on a first-come, first-served basis. Some people will be shut out because there’s only so much room. This is literally the best program I’ve ever created and it won’t surprise me if it sells out in a few hours. So keep your eyes open and jump on board as soon as registration opens. Watch the video below for a tour of some of the things I’ve used welding for over the years.
