Best Budget Welder for Flux Core Welding

3.) YesWelder MIG Pro 135A Gasless Welder

YesWelder presents a compact lightweight welder that is quite affordable when considering market prices and it offers a good power output with up to 135A.

Its compact size makes it perfect for garage welding, home repairs, and storage, as well as portable.  This can be used for some professional welding if limited to thinner metals.

The welder has an impressive duty cycle of 60%@135A using the regular household voltage at 110V. It boasts automatic wire speed settings and voltage settings that kick in depending on the amount of amperage you use to weld.

This automatic setting is terrific for beginner welders. The welding thickness for mild steel is as much as 5/32-inch.

Unfortunately, the MIG gun is built into the machine, so if you want to substitute it you will have to disassemble the welder to do so.

This welding machine uses both 0.030-inch and 0.035-inch diameter flux core wire with four-inch reels. A well-written English language owner’s manual is included in the package. It weighs in at fifteen pounds.


      • 135A output from 110V input
      • Easy to use
      • Portable  due to its lightweight and at 15 lbs.
      • Great for beginners with automatic settings
      • Clear Instruction manual 
      • Affordable

What We Considered When Selecting Flux Core Welders

You need to consider exactly what you intend to weld with your flux core welder. All MIG welders can run welding wire that is flux core. It’s sufficient to shut off the shielding gas.

Some welders use flux core wire with shielding gas still on to give more shield to the weld. However, it’s generally not necessary. Here’s what we looked for in a flux-core welder.

1.) AC or DC. Power output will influence your results. Generally speaking, AC outputs are not very good for flux core welding.

An AC output will be alright if you only plan on welding steel. Stainless steel is an entirely different story: To fuse stainless a welder with DC output will give you a better result.

2.) Lead. This may seem of lesser importance when choosing a flux core welder, but it will make quite a difference when you actually weld.

The quality as well as the thickness of your lead, can influence durability considerably. Ground lead length and torch lead length can influence the practicality and convenience of your welding session. 

3.) Longer is usually better. Our pro welders recommend ground lead that measures from ten to twelve feet and torch leads that measure anywhere from ten to twenty-four feet in length.

Not all flux core welders will feature these lengths, but longer leads will permit you to move around the materials you are welding offering greater comfort and convenience.

4.) Metal Types. It is essential to know what type of metal you plan on welding because some welding machines are better suited to specific types of metal. For example, a flux core welder cannot weld aluminum, but a multipurpose machine may be able to.

5.) Multipurpose or Single Use? MIG welding machines can weld using gas as well as without gas. This type of welder is multipurpose. If you have no need or desire to use gas when welding, you can select a single-use flux core welder and eliminate any worry relative to gas.

If you prefer to use gas to improve weld quality, then a MIG multipurpose welder will afford you the option of using either flux core or flux-less welding wires.

6.) The thickness of Plates. An important consideration is the thickness of the plate you will be welding because it will give you an indication as to what type of machine you need.

It is recommended buying a welder that can weld a plate that is slightly thicker than what you generally weld. If you are at the limit, the machine will weld but it may not be as good a weld as a more powerful welder would produce.

7.) Wire. Differences in wire diameter as well as the spool diameter, should be considered. Hobby welders will usually use a 0.030-inch diameter and will offer a standard six-inch wire spool.

If you need to perform beads that are thicker, consider this when selecting your welder. Consider a welding machine that can run a wire with a 0.035-inch diameter.

Also, six-inch spools run out quite quickly. So an eight-inch spool diameter will let you weld longer before having to reload a new spool.


Can my flux core welder to weld aluminum?

No. Flux core wire cannot be utilized with aluminum as it does not heat up sufficiently. A shielding gas, argon, needs to be used when welding aluminum.

If you wish to weld aluminum along with other types of materials, a multipurpose welder would be a more useful choice,

Is flux core welding pushed or pulled?

Pulled. Point your gun toward the weld pool and then pull the gun away from the finished bead.

What plate thickness can be welded with a flux core welder?

Generally, up to ¼-ich.

What makes flux core welding a good choice?

This type of welding allows deeper penetration and permits the welder to use the torch in various directions.

Does flux core wire go bad, expire, or deteriorate over time?

While it may not have an expiration date, it can go bad. Since this wire is not solid, contaminants can enter the wire tubing.

Lengthy exposure to moisture can ruin your flux core wire as well as exposure to contaminants resulting in deterioration.

The Bottom Line

We hope this article has helped you in your search for the best flux core welder for your personal welding needs and projects.

We really liked the Hobart Handler 140 Welder, but all of these welding machines merit consideration. We wish you the best in your search and thank you for reading.
