Best Welder For Exhaust Pipe Work! Unbiased Review

As a do-it-yourself kind of person with a damaged exhaust pipe, chances are you want to fix it yourself. And this is why you are here; you want to know which is the best welder for exhaust pipe.

Most vehicle exhaust pipes are made from special alloys such as stainless steel, carbon steel, and even aluminized carbon steel. Furthermore, exhaust pipes are usually constructed from thin sheets of metal.

As a result, not every welding machine out there is suited to welding exhaust pipes. Choosing the wrong welder can lead to more damage to the pipe. So what kind of welding machine do you need for such a delicate task as this?

After sampling many different welding machines, I have narrowed down to six. These are the ones that are best suited for the task at hand. I have selected them based on their ability to weld metals of varying thicknesses.

The best exhaust pipe welding machines

Hobart 500559 Handler 140 MIG Welder 115V

The popularity of the Hobart Handler 140 MIG led me to snatch it up for less than $500. It sports the famous gray and black color combo that has become synonymous with Hobart welders. But how does it perform?

As you may have already guessed from its name, it has a max power output of 140 amps. This is sufficient to weld metals of up to ¼ inches in thickness. It can also handle 24 gauge thin metals with ease, which is one of the reasons it earns the top spot on my list.

As a DIYer, you probably have a standard 115-volt power socket. Which is a good thing as this welding machine runs on the standard 115v power plug. It is also quite lightweight, weighing only 57 pounds, and you will have no problems moving it around.

While it is a MIG welder, it can also be used for flux-core welding. Additionally, out of the box, it comes with all the equipment you need. Thus, there is no need to purchase extra equipment to start using it.

How To Choose The Best Welder For Exhaust Pipe Welding​

Welding machines built for home use are increasingly growing in popularity. Today you can acquire a light and compact welder for your DIY repair works. However, not all will be suited to welding an exhaust pipe. So how do you know which welder is suited for exhaust pipe welding and which is not?

Several factors will help you know that a welder can handle welding exhaust pipes. These are;

Power output

A welder’s power output will determine the kind of metal you can weld with it. A higher power output means you can weld thicker metal. However, high power output is not recommended for welding thin gauge metal.

Since exhaust pipes are of varying thicknesses, a welder that is capable of welding both thin gauge and tick metal is ideal. Ideally, it would be best if you got a welder that has a power output of between 10 amps and 140 amps.

The ten amps are sufficient for welding thin gauge metal, while the 140 amps can handle thicker sheets of metal.

Power input

To use a welder, you will need to plug it to a power source. For exhaust welding works, minimal power is required. Therefore, a power input of either 115v or 120v will do fine. However, if you can go for one that has dual voltage input. Such a welder will be compatible with both a 115v and a 230v power outlet.

Duty cycle

Duty cycle is something you cannot ignore regardless of why you are buying a welder. In most cases, welders suited for heavy-duty works have a longer duty cycle. This means they can run for longer before requiring a cooldown.

However, most welders used for exhaust tube welding have a duty cycle of about 40%. This is sufficient, especially if you are welding using a low heat output. A 60% duty cycle is, of course recommended.

Adjustable wire feed speed

The speed at which the welding wire is fed from the welding gun is crucial to the quality of the finished weld. To slow, and the result is an unsightly and messy finish that will not be strong. If the speed is too high, the result will be spatter everywhere.

For the best results, go for a welder whose wire feed speed can be adjusted. This way, you can adjust the rate based on the welding task at hand.


The Best welder for exhaust pipe is one that can handle welding metals of varying thicknesses. More importantly, it should meet your needs. The six welders reviewed above have different features that earn them a spot on the list.

Each welder is suited to different welders. Some will appeal more to those on a strict budget. But there is also something for those looking to splash money to get quality.
