FAQs

Is it OK to buy a used welder? ›

A used welder doesn't mean that the machine isn't any good or is of low quality, it just means that the machine has been used for a while and was probably traded in by the original user for a newer model. There are many expert sellers, like Vern Lewis Welding Supply, who offer quality, used welders for great deals.

MIG Welders (GMAW or Gas Metal Arc Welding)

MIG (metal inert gas) welding is an excellent choice for beginning welders. This easy-to-handle machine is usually spool-fed to create professional-looking joints on both thick and thin metals.

A welder such as a Millermatic 211 or Multimatic 215 welder is typically able to handle most household projects, but some welders prefer to use a 220V welder at home so that they can weld thicker steel on heavy-duty projects and achieve sufficient heat to create a strong weld.

For most home welding projects, a MIG welder is a good choice because it is easy to use and can handle a variety of materials. However, if you plan to work with aluminum or other non-ferrous metals, a TIG welder may be a better choice.

Expect to find arc welders in the range of $100 to $1,000, with basic models starting around $100 and feature-rich machines reaching closer to $1,000.

American Welding Society – industry standard

Every six months after you receive this certification you must submit a maintenance form to AWS verifying that you're still performing the same welding you were initially tested on.

Some argue that stick welding is stronger than MIG welding, since it offers better penetration for thicker materials. However, MIG welding can provide good welds despite not being as effective on thicker metals, and is better for joining thinner metals with a good finish and less risk of burn-through.

Tungsten Inert Gas (TIG) welding is widely considered the most challenging welding process to learn. The sheer complexity of the technique requires more practice and focus to master than other less-technical welding methods. TIG welding also results in some of the strongest and sturdiest welds in the industry.

What's the easiest type of welding to learn? MIG welding is generally the easiest type of welding for a beginner to learn. MIG welders use a feed wire that runs through the machine at a preselected speed. This makes the process relatively fast and produces consistent welds.

Most consumer-grade welding equipment operates on a single-phase power supply, available through standard 120-volt or 240-volt outlets. However, industrial-grade machinery often requires a 3-phase power supply to effectively meet higher power demands.

Which is better, MIG or flux? ›

Flux Core Welding

This results in a structurally strong weld, but one that is more mixed than either TIG or MIG welds. Properly performed MIG welds are objectively of metallurgically higher quality than equivalent FCAW due to the gas shielding.

MIG Welders

There are many different types of welders, but metal inert gas (MIG) welding is generally considered the most suited to beginners or hobbyists.

MIG is generally seen as being easier to learn and perform as well as being faster and better for welding thick materials. However, TIG welding offers greater control and precision, is better for thinner materials and offers neater welds with little finishing required.

The MIG, gasless MIG, and stick welding processes are the most appropriate for home welding needs. But having a TIG support comes as icing on the cake, allowing you to complete even the most delicate jobs, like fixing a visible metal piece of furniture.

Some welders work in factories, construction sites, or shipyards, while others may work in smaller shops or repair facilities. Welders may work in tight spaces, at heights, or in uncomfortable positions. Safety concerns: Welders must follow strict safety protocols to protect themselves and others from injury.

A good weld should be visually appealing, with a smooth and uniform weld bead that shows proper fusion and penetration. Bad welds, on the other hand, may contain defects like porosity, pinholes, or slag on the weld surface, which can compromise the strength and reliability of the weld.

Take it to the pawn shop. Apparently, the pawn shop is the first place to go if you are looking to get rid of an older welder with life left in it. Don't expect to receive much more than the equivalent scrap weight for it though, and if you ever decide to buy it back, it will likely cost you more than if it was new.
