What to Look for in a Flux Core Welder – Buyer’s Guide

Wire Compatibility

Don’t forget to consider your consumables when purchasing a flux core welder. Most welders are only compatible with particular wire sizes. Some machines can only accommodate specific spool sizes. If you’re just doing a little DIY welding, you should be good with 0.03-inch diameter wire. Larger wires produce thicker beads. Therefore, wires that are 0.035-inches in diameter or larger are more suitable for commercial applications. If you are welding on a small scale, you don’t need to worry about your welder’s spool capacity. While some welders are willing to upgrade their small-scale flux core welders to fit larger spools, we don’t recommend this.

Most manufacturers also specify the metals that their welders can fuse. Most machines are suitable for steel. You may be able to add on features so that you can use aluminum and other delicate metals. Never use a flux core welder on metal that is not compatible with the system. Inadequate pairings could infringe on your safety and the survival of your welding machine.

Safety Features

Whenever you’re working with molten metals, safety should be your top concern. Look for welding machines with automatic heat protection, powerful fans, and plenty of air vents. You’ll also need a lengthy ground cord. We prefer ground wires that are 9 feet or longer. Don’t forget your protective mask. It’s an integral part of any welder’s uniform. Many manufacturers throw these accessories into their welding kits.

Your Work

Ultimately, you need to choose a flux core welder that will help you finish your target projects. Amateur welders don’t need to worry too much about their consumables and plate sizes, but commercial welders do. You’ll want to make sure that your welder is compatible with your metals and wires of choice.

Does your work take you to remote locations? If so, you’ll want to invest in a compact, lightweight model. What’s more, consider the thickness of the plates that you are welding. Depending on the size of the consumables that your machine uses, you may only be able to weld metal that is a fraction of an inch thick.

Spool Size

Flux core welding wires come with different size spools. Most home welders use one- and two-pound varieties. Meanwhile, commercial welders use even larger consumable packages. Since MIG welding wire is likely to rust, you must use a spool size that you can use up relatively fast. Keep in mind that you may be able to save money by investing in larger spool sizes.

Price and Warrantee

Flux core welding requires a unique set of skills. These are not your run-of-the-mill DIY tools. However, consumers can choose between home and commercial varieties. Think of your flux core welder as a personal investment. Make sure your machine is covered by a manufacturer’s warranty.
