Guide to Buy the Best $300 Flux Core Welder

Yes, there are 7 options to choose from above, but how do you identify the best flux core welder? Check out the section below to find out!

Duty Cycle

Any flux core welder when used for a prolonged period of time is prone to overheating. Overheating can result in damage of the device or short circuit. To avoid the machine from blowing up, every welder has a duty cycle of 25%, 40%, 50%, etc.

To demonstrate how it works, if your flux core welder has a duty cycle of 30%, that means it can weld continuously for 3 minutes in a span of 10 minutes. So, the device would not work for the next 7 minutes.

HITBOX 3 In 1 MIG Welder has a duty cycle of 40% at 120 amperes. It can run for 4 minutes in a span of 10 minutes while taking a break for the next 6 minutes.

Energy Efficiency

When it comes to welding as well, you should consider saving energy and bills. Thanks to modern technology, you can get your flux core welder with an energy efficiency option!

KICKINGHORSE F130 UL-Certified Flux Core has a conversion rate of 80%, allowing you to save 20% of energy bills!


The capacity of the flux core welder is based on the type of material that needs welding. For example, if you need to weld a thin sheet of metal, a welder that operates at 120 volts or less is enough to get the job done.

On the contrary, for a heavier workload like maintenance and repairs, you may want to get something that runs at 240 volts. Luckily, there are flux core welders that run on dual voltage, such as HITBOX 3 In 1 MIG Welder.
