What is Spot Welding?
Spot welding is basically the process where two contacting metal surfaces are joined together. Usually, the metals that are spot weld are really thin and have a thickness ranging from 0.5 to 3mm. If the metal sheets are thicker than this, you can’t spot weld them since heat flows to the surrounding metal very quickly.
For spot welding, you have to use a spot weld cutter that has two shaped copper alloy electrodes. These electrodes concentrate the welding current into a small spot to clamp it together. When a large current is passed through this spot, the metal will form a weld.
The most interesting fact, however, is that in spot welding a lot of energy is delivered to the spot in a very short span of time. This is, in fact, what allows the welding to be done successfully without heating the surrounding metal sheet.
And, the amount of energy delivered is usually matched with the sheet’s metal properties. The most common use of spot welding is probably in the automobile manufacturing industry. Besides orthodontists also use this to for resizing molar bands and is even used while manufacturing batteries.

What to Look for In a Spot Weld Remover?
Here are the things you need to consider before making a purchase decision.
When you purchase something, you want it to last. The same is the case with spot weld cutters.
And if you want your weld cutter to survive many years, then you just focus on the materials. If the material is of high-quality, you can rest assured that you are not wasting your money.
- Cutting Blades
Perhaps this is the most important feature that you should look for while purchasing a welded cutter. If the blades are good and sharp, then the product is good as well.
Also, check how many blades you will be getting and if there are replacement blades as well.
I always emphasize getting products from renowned brands. Yes, sometimes they are a bit pricey, but they offer you high-quality products as well.
That’s why I always prefer to spend a bit extra by purchasing from known brands rather than risking my money by shopping from cheap companies.
However, you need not worry about that. All the brands that are featured in this review are highly-reputed companies that are 100% trustworthy.
If a manufacturer offers a guarantee on a product, it demonstrates that they believe in their items. Also, by buying products with a warranty, you safeguard your money. If something happens to the product, you can get it replaced and save your money from being wasted. That’s why I prefer buying products with warranties.
You need to keep in mind that you’ll have to pay good money for quality products. That said, all expensive products aren’t of good quality. In fact, some budget products often give a far better performance than the high-end options.
So, you have to find a cutter that’s within your budget but offers what you desire.
