The best flux-cored welding machine buying guide

Input Power

Most flux-cored machines run on either a 110v or a 220 v power circuit. However, some run on both. For a beginner, a machine that runs on the 110v circuit is a better choice. The reason being that this power circuit is most common in most homes. 

For more demanding or industrial projects, you may consider going for one that runs on both. This may end up costing you slightly more money though.

AMP rating

The max amp rating of a welding machine will give you a clue of just how powerful it is. Also how thick or thin of material it can handle. A machine with a higher amp rating will be able to handle thicker sheets of metal.

For light to medium work a max amp rating of about 140 amps is enough. For industrial projects, a max rating of 200 amps will be ideal. Thus, this depends on how thick or thin the materials you will be welding are.

The duty cycle

A machine with a duty cycle of 30% will need to cool off for at least 7 minutes after 3 minutes of continuous welding. This percentage is thus an important factor to consider. Some of the more affordable machines have a duty cycle of about 20%.

For demanding projects, a duty cycle of about 50% and above will be ideal. However, for light to medium tasks, a lesser duty cycle will do. However, the higher the duty cycle the better.

Conclusion

There are countless welding machine options to choose from. Some of them offer better value for money than others. But ultimately it depends on what you intend to use the welder for. For light to medium tasks, an inexpensive model with just the right features will do.
