• How To Master MIG Welding If You're A Beginner

• My name is Garrett Strong
• Ive been helping beginners hobbyists learn to
  weld online for several years now. Ive helped
  thousands of people just like you get started
  learning to mig weld. If youd like to get

• If youd like to MIG weld aluminum with your wire
  feed welder, this step-by-step tutorial will show
  you how
• If you havent yet mastered MIG welding mild
  steel, then you probably need to do that before
  you start aluminum welding with the GMAW (MIG)
  process.
• Heres why
• When MIG welding aluminium, you use the same gun
  angle and gas flow rate (20-30 CFH).
• However, thats pretty much where the
  similarities end.

MIG Welding Aluminum Basics

• Aluminum is a tricky metal to weld with a MIG
  welder because it takes more heat than mild steel
  (Usually in the range of 21 to 24 volts). The
  minimum aluminum thickness you should attempt is
  roughly 14 ga. To 18 ga. Any thinner than that
  and youll need a TIG welder.
• Aluminum welding with a wire welder is notorious
  for having unexpected burn through, and the weld
  puddle will literally fall right through the work
  piece if youre not moving fast enough. Thats
  why you shouldnt attempt to weld thin pieces of
  aluminum.
• When youre MIG welding mild steel, you can and
  should move the MIG gun slow enough to get deep
  penetration. Yet, with aluminum, the weld puddle
  resembles that of wet foil.

Steps To Master MIG Welding Fast

• Step 1 Forget Welding Safety
• Of course, thats not to say welding safety isnt
  important. Its obvious that you WILL need a
  welding mask, gloves, long sleeves, leather boots
  (and a welding hat if youre welding overhead).
• However, your main safety should focus on making
  solid welds that hold strong. Imagine if you
  welded a trailer and you were pulling it on the
  highway at 70 m.p.h. Then, out of nowhere you hit
  a large pot hole, and BAM. The trailer suddenly
  jolts, cracking the welds. The next thing you
  know your trailer is now an out of control
  missile waiting to destroy any vehicle unlucky
  enough to be in your immediate area.

Step 2 Stop Focusing On Perfect Welds

• Many welders in the online forums will try to
  convince you that your welds need to look
  perfect, or you shouldnt try at all. This is
  complete hog wash. Wouldnt you like to Master
  the fundamentals of MIG welding first so you can
  make great looking welds later on, or would you
  rather listen to these ego maniacs and just give
  up because they said your welds arent perfect?
• The truth is, your welds arent going to be
  perfect. Besides, the purpose of MIG welding is
  first and foremost to fuse the base metals
  together, not to be perfect.
• Theres a smart way to PERFECT your MIG welds
  well cover that in a minute. And, whats great
  is that you will cut your learning curve in half
  when you do this.

What Is A Wire Welder?

• When you buy a wire welder you will have the
  option to buy one that you can hook up a gas tank
  to, or you can buy a wire welder that uses only
  flux core wire (gasless).
• A word of advice if youre a complete beginner to
  welding wanting to to learn how to mig weld.
  Choose a wire welder that has the ability to hook
  a gas cylinder up to because you can use it as a
  MIG (Metal Inert Gas) setup, or use it as a flux
  core welder.
• If you choose to use it as a MIG welder then you
  will have to get a bottle of 75/25 (argon/CO2),
  or straight CO2 so you have shielding gas
  provided at the weld puddle.
• If youre wondering what shielding gas is when
  using a wire welder, its used to protect the
  molten weld puddle from atmospheric gases that
  will weaken the weld if the weld puddle is
  exposed.
