How To Mig Weld
If you are wanting to
know how to mig weld you have come to the right place.
Here you can find some
free mig welding how to tutorials that I have made. Mig welding machine are
now very affordable to most people. There are heaps of little jobs that you can do around the house with one
of the smaller DIY mig welders.
Let
me tell you now, mig welding is about ten times easier that using a stick welder. Even if you are using gasless
flux cored wire it is so much more easier to do that learning how to
arc weld.
How to mig weld
instructions
With a little practice anyone can do it. Below I have added the links to the
pages that will take you through learning how to mig weld uding a mig welding mahine. This is a great place to
start especially if you have never used a mig welder before.
How to set
your mig welding voltage and wire feed speed for that ideal welding arc. You need to set your wire
feed welder up properly so that you can get a good wire burn and good penetration and fusion. Check out
this page with examples and a video showing you what's what.
1. Mig welder power
connections. Depending on where you live in the world you
will have different power requirements for your machine. Some places like in the USA have both 110
volts and 220 volts. Here in Australia we only have 240 volts. That is for single phase, and for
three phase power it also varies as well.

2. Duty cycle of the welding
machine It is important to know what the duty cycle of your
mig welder is. This is especially important if you are looking to buy a mig welder. You
will need to know how to tell which machine has the best duty
cycle.

3. Mig welding
consumables When you are welding there are certain parts on
the machine that will wear down over time and will need to be replaced. These are called
consumables and every mig welding machine has them.

4. Mig wire There are various
grades, sizes, types and specifications of mig wire that are used for wire feed welding. Such
welding wires are Co2 mig wire, aluminum wire, gasless mig wire, flux cored wire, stainless mig
wire and the list goes on. Find out which wire is best for your situation before you start mig
welding. Make sure you don't go and buy the wrong mig wire.

5. Putting the wire on This tutorial shows
you clearly how to put the mig wire onto the welding machine. If you have never installed any
mig welding wire before you can check out this guide. It has photos and and easy to understand
description of how to do it.

6. Drive rolls The drive rolls or
also called feed rolls are what push the mig wire along the inside of the mig welding gun.
There are a few different types of feed rollers you can get for mig welding machines. For
example, you need to use a smooth or v groove roller when using solid mig wire. Aluminium mig
wire and flux cored mig wires use different feed rollers.

7. Gas regulator If you are welding
with a non gasless mig welder you will need to use a gas regulator. The gas regulator is
designed to regulat the flow of the shielding gas so that it can allow you to weld
properly.

8. Mig welding
modes Depending on the model and size of your mig
welder you may have extra controls that you can set. On this page we look at the most
basic of mig machine controls which are, wire feed speed, burnback control, spot welding
mode, stitch welding, and continous welding modes.

 9. You may also want to look at the most
common welding positions, and what they are
called etc.

Maybe you want to make some DIY welding projects around the house. Maybe you need
to fix up some equipment on the farm. Or maybe you just want to get a career as a boilermaker, fabricator or
welder.
Mig welding is the most widely used welding method to join bits of metal
together.
From high end industrial welding robots running 24hrs a day right down to someone
at home in the shed with a small gasless mig welder. Mig welding is here to stay.
Make sure you are wearing the proper workshop welding clothes,
hearing protection and eye protection otherwise you will get burnt, blind and deaf.
Learn how to mig weld
The learn how to mig weld steps are found in the navigation
menu bar to the right of this page.
Before you start to weld here are some quick welding tips below
to get you started. If the steel that you are going to weld is not clean, you can have all sorts of problems.
Penetration and incomplete fusion will happen. There will be a lot more spatter and it will be hard to make the
perfect weld.
Quite often a lot of problems can be traced back to having a
bad earth connection.
Here you can find a basic walk through of the components and
parts to any compact wire feed mig welding machine. Here I go through and show
you step by step how to put on a roll of wire onto your welder. It's an easy task to do.
You have to put down small little tack welds first before you
go an fully buzz up the work. This is so that you can hold the parts in place and get them square. Tacking is a way
of controlling the effects of distortion. Hopefully you should be
able to learn how to mig weld steel with my tutorials.
