Buyer’s Guide: Things to Consider when Purchasing a battery spot welder
A buying guide is significant when you want to purchase something important and desire to look into the features closely. Spot welding requires you to purchase a welding machine that applies to the thicknesses of workpieces you are probably going to use. You will need to buy a machine that produces the proper amount of current and pressure to spot a weld satisfactorily. So, to let you familiarize yourself with the specifications, here is a quick buyer’s guide to ease your purchase.
Battery spot welders come in various quality which you can find in the welding machines specification portion. Is the spot welder durable? Will it be able to produce a smooth weld? A battery spot welder that has a duty cycle of 50% or more is proven to deliver quality welds. Also, the welder that applies to various workpieces is definitely good.
Some welding tool comes with a cable while others don’t. The cable ones will let you stay on the table for a longer period whereas the other ones are portable. If it’s heavy, you might be in trouble. Often stationary machines are heavier and need prior experience to use. However, they possess greater power to weld thicker metal pieces than the lighter ones. Portable machines, on the other hand, allows you to move wherever you want. They come in handy when working on small projects at home or farm.
One amazing advantage of a battery spot welder is, it applies to a wide variety of metals. When working with nickel, stainless steel, titanium, and wire mesh, spot welder works splendidly. Another important thing to consider is the thickness of the metal you would work with. The rule of thumb is to work with a 3:1 ratio of thickness level. For instance, if you are joining two separate pieces of sheet and one is 3 mm, the second one should 1mm thick. Unfortunately, aluminum, galvanized steel, zinc, etc. that do not conduct electricity are difficult to weld with a battery spot welder. Make sure to consider the metal used when spot welding.
You might wonder why you would choose a battery spot welder over any other kind? One obvious reason is the effortless smooth joint it creates. Luckily, battery spot welders are also lightweight and designed compact. This allows you to relaxedly carry the welder to your job sites and store it in minimum space. Portability is one significant factor to consider when purchasing a battery spot welder to enjoy better benefits.
No matter what welding machine you are purchasing, you shouldn’t overlook the duty cycle. The duty cycle gives you a measurement of how long the welder will continuously work before resting. If the machine is rated 60% at 100 amps, it implies that the machine will operate 6 minutes out of the ten-minutes working period and the rest 4 minutes to restart the process. A higher duty cycle indicates greater efficiency.
Battery spot welders come in many different price ranges. If the qualities seem worthy, you can opt for higher range ones. Even there are available spot welder machines that won’t break your bank yet let you experience smooth performance. The decision is up to you whether to spend more or less.
Many battery spot welders come with additional features that others do not have in particular. For instance; few battery spot welders come with an extra pair of welding tips or maybe the spot current rate is pretty high. While many have an advanced cooling system to prevent overheating and others don’t. Consider additional features to ease your spot-welding journey.
