Who Should Buy This?

A MIG welder is used by many different people for a number of shop and factory applications. It is also a great choice for home repairs, hobbyists, and welding enthusiasts. A MIG welder can be used on various metals such as stainless steel, mild steel and aluminum of all thicknesses.

It is used by contactors, automotive shops, welding shops, boat and plane builders, metal factory workers, construction workers, handymen, welders, DIY-ers, home owners and anyone who has some repairs to do that involve welding.  It is a very easy process to learn and isn’t as complicated as other forms of welding.

What Makes a Good Mig Welder?

When you are looking for a good MIG Welder, there are several things that you will need to consider, the first of which, is understanding what your specific needs are.  If you will just be using the MIG welder for around the house repairs or will it be used for more professional use in a garage?  You want to be certain that you choose the right MIG welder with the right amount of power to fit the tasks and jobs you will be doing.

Mig WelderThe best type of welder to look for is a multipurpose machine that will handle general home repair, ranch tasks and jobs, auto body jobs, maintenance and repair and many others.  To do those types of jobs you will need features like auto-set systems, a standardized built-in solid contractor circuits, and thermal overload protection just to get started.

The power requirements you will have for a basic MIG welder are 115v. Most home projects involve welding thin metals, including iron.  If you need a welder that handles both thin metals and thicker metals, look for a mig welder that operates at 230v or 120v.

They may cost a little more but the versatility they offer is well worth the extra cost.  If you’ll be handling heavy duty projects, look for a mig welder that has the power to handle those heavy duty jobs.

One of the common problems that mig welders can encounter is overheating.  Once they overheat you have to leave them off for a significant period of time to cool down sufficiently so you can work again.

Thermal overload protection is one way that you can avoid these overheating problems.  This is especially important for welders that need to be used for any length of time. Knowing what you are going to use the welder for is important in choosing the right mig welder.

Are you going to use it in a mobile welding shop or one that is stationary?   If you are going to be mobile, you will want to choose the lightest welder you can get for the money you have to spend.  Don’t sacrifice quality for size. Size can be worked around, quality cannot.

Look for mig welders that are easy to maintain, and that offer good warranties and good repair options as well.  You have to know that the mig welder you purchase has the available parts that would be needed in the event a repair is necessary.
