Thinking about purchasing a MIG welder.





Not planning on any serious frame welding though. Mostly repairing small items. I could used it to weld my oil pump pickup etc.

It is a 110v unit that puts out up to 130 Amps.
Here is a link to the one I bought:

It comes ready for flux core - with the option to buy a tank/regulator for MIG welding.
One thing to keep in mind is adjustability. Mine has infinite wire speed
control, with four heat settings. The more expensive units have infinite heat
settings, which can make it much easier to dial it in to the job.
The price at a local hardware store was about $300. The CO2 tank was about
$100 - but I got a fairly large tank. You can get a small one for about $60.
I bought the tank at a local gas supplier. When you go to refill it, they give
you a new tank - leak tested, etc - like an exchange program.
Welding helmet: $20 for fixed shade - about $100 for auto shading.
Have fun. :seeya

What kind of gas do these welders use and where do you get the gas? :confused:
The company I got mine from is - Wesco - division of AGA Gas.
They had a decent showroom, and tons of welding supplies.
The guys there even talked with me for a bit to select the proper gas to do
the welding I intended - and gave me a few tips, too.
for carbon steels the gasses most used are:
CO2, Argon + 2-20% O2, Argon + 5-25% CO2
For non ferrous it's Ar or Ar + He (helium)
If you're a starter CO2 is the easiest since it leaves the plasma hotter, Argon (based) gives less spatter but can lead to poor penetration due to it being colder.

Lincoln makes a good unit.
So you need a 220Volt unit, a flow meter and a bottle of gas. Argon/Carbon dioxide mix.
I teach a welding coarse plus have 4 welders in my personal shop.


If you have the 220 Volt power then I suggest a 220 (lots of good ones to choose from) but don't rule out the 110 Volt machines.

I got mine with a free cart and at the moment am using strictly flux core but agree that gas shielding makes a nicer weld. I have been able to weld seams on my frame, a broken tranny mount bracket, the busted railing at my house, and several other things for friends. The only downside I have seen so far with this unit is the short duty cycle, but when welding small things, it will never be an issue.
Keep in mind that there are other expenses as well. A decent helmet (most 'kits' come with a ridiculous hand held shield) is necessary as is gloves, jacket, extra wire, chipping hammer. I have also started buying those cheap knockoff vise grips whenever I see them. A tank of gas if you go with sheilded wire wil run you about $100 for a short one or $150 for a tall on. The miller comes with the regulators and hose for the tank.
Also, even tho flux core wire is a little more messy than shielded, using a wire wheel in a grinder will clean it up enough that you cant tell the difference.
