  • Input Voltage-  115V
  • Rated Output- 125 AMP output
  • Weight- 32 pounds
Ironton 125 Flux-Cored Welder

The Ironton is not a multi-purpose welder as it does not have the versatility and functionality we see on other premium welders. However, it lays a decent performance, especially considering the price point and what it’s made for.

WHY IS THIS A TOP PICK?

Duty Cycle

Like the previous Hobart we reviewed, this unit comes with a duty cycle of 20% at 80 Amps, which is pretty decent and reasonable for this class of welder.

Performance

The Ironton is a value-packed welder that lets you get more than you paid for.

This unit has a decent welding output range of 60 to 80 Amp. Better yet, the unit has a peak of 125 amp, tying with the premium Forney 125 we had reviewed at the beginning.

Best Flux Core Welder Buying Guide

Before we look at some of the factors to consider when purchasing a flux core welder, let’s look at the benefits of using a flux core welder over other types of welders.

Portability

With a flux core welder, no need for shielding gas, so no need for carrying a gas tank.

This translates to greater flexibility and portability.

Welding Flexibility

Speaking of flexibility, the flux core welding torch can be held in several directions, one of the major reasons why this type of welding is better suited for commercial and industrial welding tasks.

No Need for Clean Joints

Contrary to TIG welding, MIG welding is resistant to external elements. In any case, the only thing that you need to remove for flux core welding to happen is moisture, oil, and paint.

This welding is ideal, even on the rusty and dirty metal surfaces.

Greater Penetration

Flux core welding has greater penetration than a majority of the welding processes, and this is one more reason that underlines the suitability of this unit for the heavy-duty tasks.

Factors To Consider When Choosing a Flux Core Welder

If you are in the market searching for a flux core welder, there are several critical components that you need to have at the back of your mind.

Some of these components are essential in the overall performance of your welder.

Let’s look at some of the three critical components;

Input Power

A majority of the welders run on either a 10V or 220V power circuit. However, some of the flux core welders run on both.

Ideally, it's best to have a unit that runs on 115V power circuit since this option is most common in households. However, if you are to handle more demanding industrial tasks, you need to choose the  220V option as it delivers more power.

AMP Rating

Speaking of power, the AMP rating is a depiction of the strength of your flux-core welder. Besides power, it also gives you an idea of the thickness or thinness of a unit that can handle.

A flux core welder with an AMP rating of 140A is ideal for the lightweight to medium tasks, while the 200A welders are ideal for the heavy-duty industrial tasks.

Ultimately, the amp rating will depend on the thickness of the metals you want to fuse.

Duty Cycle

The duty cycle is the amount of time that a welder can work without taking a break. The cycle is expressed in terms of a percentage and measured in a 10-minute cycle.

For instance, a unit with a 20% duty cycle means it can only weld for 2 minutes before cooling for eight more minutes.

For industrial purposes, it's required that your unit has a duty cycle of at least 50%.

Conclusion
