The 5 Best Welders for Go-Kart Frames

When it comes to fabricating your own go-kart frame, you’ll need to choose the right material and tools! If you’ve opted for steel as your material for the go-kart frame, then you should definitely consider a high-quality welder. This will allow you to create a durable go-kart frame that acts as a base for all of the other components. 

While you are able to use nuts and bolts, welded joints for frames are typically stronger and also tend to last longer. The best welders for your project are typically of high quality and power, easily transportable, and are feature-rich!

Go-Kart Frame Welders – Buying Guide

When it comes to choosing a welder for your kart frame, it’s important to acquaint yourself with some of its technical details, type, voltage, current range, duty cycle and portability. Let’s take a closer look at these aspects and things you should consider, before buying a welder.


There are two types of welders featured in this list, MMA and MIG welders. Both of these welders can be used to construct your go-kart frame. However, there’s a need to differentiate between them, as they both have their own advantages. 

Manual Metal Arc (MMA) welders, also called arc or stick welders, use fusible electrodes in combination with a shielding gas to melt the steel for your go-kart frame. MMA welders are great for using indoors or outdoors and require a little more experience and coordination. The process also creates extra metal, which needs to be grinded off.

Metal Inert Gas (MIG) welders use a consumable gas that won’t work well in the wind. Therefore, MIG welders would only be suitable if you’re working on your kart indoors. They are easier to use and beginner-friendly and also work well when fabricating your go-kart frame. Take note that the gas has to be topped up once in a while.


Certain welders only work at a specific voltage, whereby others feature an input voltage selector that lets you choose between 110V or 220V. The difference is in the way they are wired and you should always ensure that it matches the voltage of your outlet. 

Houses in Europe and Asia typically use a supply voltage of 220 and 240 volts, whereas in North America (United States and Canada) 110V is the norm. When in doubt, you should opt for a welder with adjustable input voltage. 


When it comes to welding steel for your go-kart frame, you’ll need to take into account the amount of amps your welder can output. The thicker the steel tubing you are welding, the more amps your welder needs to operate with. Depending on your go-kart frame design and tubing thickness you can take the below recommendation as reference:

  • 1/8-inch steel thickness: 70+ Amps
  • 1/4-inch steel thickness: 120+ Amps
  • 1/2-inch steel thickness: 200+ Amps

Duty Cycle

The duty cycle of a welder indicates how long a welder can remain operational at a certain current. The duty cycle value is shown in percentage (e.g 60% at 120A) and should be understood as the following: 60% welding usage, 40% rest.

Operating your welder at a lower current will increase the duty cycle and will also allow you to do welding work on your go-kart for longer periods of time. Welders nowadays have an overload protection sensor that automatically shuts off, to prevent thermal damage to the welder. 


Depending on where you’re building your go-kart, you may want to consider the portability of a welder. Many people tend to shift their location from a workbench, to the floor or even outdoors. If you’re going to be changing locations more often, it’s best to invest in a portable welder. 

All welders in this list above are great for fabricating a go-kart frame, as they are portable and light, weighing only between 15 – 60 lbs. They also come equipped with a carrying handle.
