Guide for buyer’s
As you can see, choosing the best spot welder can be frustrating. With so many spot welders on the market today, there are many options to choose from, making it hard to decide which to go for. In this section, we share some common things that you should consider before choosing a spot weld machine:
The first thing that you need to look for in a spot welder is its features. As you know, there are different types of spot welding machines available on the market today. Most of them are designed to perform the same basic function. So, how you choose the one that suits your needs best depends on your budget and other things.
The thickness of the material you want to weld will determine which type of spot welder you should choose. Most spot welders have a maximum thickness of 1/8 inch. However, they are not suitable for welding thicker materials. For heavy duty jobs, it’s best to get a full size MIG welder.
The input voltage will also impact the performance of your spot welder. It’s best to choose a model that has the same voltage as your power supply or one close to it. Never use a welder with a higher voltage than your power supply, as it can cause damage to the tool and even start an electrical fire.
The welding current is measured in amps. It’s best to select a welder that has the maximum current recommended by the manufacturer. The higher the current, the more powerful your welds will be. However, it’s important to choose a model that will not overload your power supply and start an electrical fire.
Temperature & Torque Control
When you’re welding, materials usually expand when heated which can cause stress on your tools or even damage them. This is why most spot welders come with temperature and torque controls. They allow you to adjust the temperature and torque to suit your needs.
The work cycle of a spot welder refers to the time it takes to cool down and power up after each weld. Because spot welders are mostly lightweight and handheld, they need to cool quickly between welds. Some models can be set to withstand a continuous work cycle of 5 seconds while others can handle continuous use for up to 2 minutes.
If you plan to use your spot welder for extended projects, you need to consider the duration of the batteries. Most spot welders run on a DC battery. The most common is a lithium ion battery.
There are many different controls that you should consider when choosing the best spot welder. Most of them include:
Screen: This screen is designed to show the voltage and amps as well as the current being used by your welder. It’s usually made of glass or plastic; some are also touch-sensitive.
Resistance Range: Some of them have a strong resistance range that ranges from 20 to 500 ohms.
Connection Type: The connection type can either be AC or DC power. Both are designed to work with different types of batteries.
It can be hard to find the best spot weld machine for the money you spend. Like any product, some of them will work better than others. If you want to get a spot welder that gives you flawless performance, good value for money and long lasting use, our top pick is Stark USA 55010 Spot Welder.
