Choosing the Right Machine for You

Whether you're a professional welder with industry experience or a weekend warrior with a welding hobby, the first thing you need is a welder.

There are a few factors that you should consider before diving into buying a machine. These include the material, the material thickness, the weld type (MIG, TIG or stick), the power, and, most importantly, your budget.

The material you want to weld, and its thickness, will determine the welding process that will work best for you, especially as not every welder can do every material.

What material are you going to be welding?

How thick is the material you plan to weld?

These sizes are subject to the power your welder can output, so always check the product specifications.

What's the difference between MIG, TIG & Stick?

Now you should have a decent idea of which type of welding you think will work best for your needs; we can start narrowing the options even more.
