Step 1
Decide on a gas or gas-less MIG welder. Gas MIG welders require disposable or refillable gas bottles. Non-gas MIG welders don'y use gas and cost less for the initial purchase. The wire for a gas MIG welder costs less than the wire for a non-gas MIG welder. Most experts find gas MIG welders produce cleaner welds than non-gas ones.

Step 2
Consider the amp rating. MIG welders with a lower amp rating weigh less than higher amp rated welders. While a 90 to 100-amp MIG welder works for basic repairs, you lose versatility for wire speed and power options with a lower amp.

Step 3
Evaluate the type of metalwork you need to do. The more versatile the MIG welder, the more intricate metalwork you can weld. Adjustable settings allow a novice welder more control over the variables.

Step 4
Look at brand name MIG welders. Lincoln Electric has been an industry leader in MIG welders for years and continues to lead the field in flexibility and high-quality welders. Name brand companies often offer attractive warranties, like the 3-year parts and labor warranty Lincoln Electric offers.

Step 5
Compare used and discount prices to new models. With a new machine, you know exactly what to expect. For used machines, you don't know the type of work the welder did with the machine or the wear and tear on the machine. Discount companies often sell discontinued models that are new and provide a good quality for a lower price.
