Things to Consider While Buying Flux Cored MIG Welder

1. Which one do you need: flux core or MIG?

All MIG machines can run flux core, but not every flux core welder can run like a gas MIG machine. So, this is an important detail to pay attention to. Understand your requirements, for now and for the long term. If you wish to, later on, try MIG welding, you would want to invest in a MIG welder.

2. Thickness of the metal

The single most significant factor in choosing your best flux core welding machine is how thick your metal is.

If you only weld metal that’s 1/4-inch thick or less, you require 130-140 amps. To weld anything wider, you will need a machine that can weld up to 3/8-inch steel with over 200 amps of output.

3. Input Power Sources

If you are welding sheet metal or thin plate-like gate hinges, a 120-volt machine will be more than enough.  For heavier work, you will need more input power than that.
