Best Welder for Exhaust – Buyer’s Guide
Like any other machine, you should be definitely interested to know about the exhaust welder you want to buy. Therefore, it is essential to know about the features required before purchasing the best welder for exhaust. Here are several important things that you need to consider in an exhaust welding machine before purchase.
- The Power
There are two main factors regarding power, i.e. power output and power input. Power output depends on the kind of work you will be doing and what is the frequency of that work. For minor tasks and projects, a 100 amps welder is more than enough. But for a heavy application, you need a welder with 140 amperage value. In the case of power input, it should be a little lower than output power, i.e. a 140 amps welder will be needing 120V to power.
Exhaust welding machines can vary in weight depending on their size. Bigger welding machines have high output power but they are heavy as well. These machines also take a bit more space than normal. If you need to shift your machine from time to time, you should consider the one with a smaller size. Remember, some small-sized machines can also deliver higher power outputs.
- Duty Cycle
The duty cycle is the amount of time within 10 minutes that a welder can perform without overheating. It is expressed in percentage. For example, if a welder has a 40% duty cycle at 100A, it means the welder can operate non-stop for 4 minutes before requiring 6 minutes to rest. A lower power output allows the user to weld for longer periods without requiring rest.
- Safety Features
When buying a machine for exhaust welding, one must look for appropriate safety features. Good exhaust welders always have built-in safety features for maximum protection while welding. Thermal overload protection is a must-have safety feature one should look for. It helps prevent you from going beyond the mentioned duty cycle by automatically shutting the machine at the end of the cycle. Another important feature is the built-in contactor that instantly cools down the wire till the trigger is pulled.
- Wire Feed Speed
Wire feed speed is the speed at which the welding wire is fed to the gun. The wire feed speed must be adequate, if it isn’t, the welding wire will disappear when it touches the metal resulting in an uneven, messy, and poor weld. If the speed is too high, it will result in wire stretching from the gun and will cause wire spattering problems. The best welder for exhaust always has the automatic wire feed settings for speed adjustments according to the power.
Best Welder for Exhaust – FAQs
1. Is it possible to MIG weld stainless exhaust?
It is definitely possible to MIG weld stainless exhaust but not much easy. You need to use a gun liner in which regular MIG wire has never been used for a long-lasting weld. You also need the right kind of shielding gas to bond stainless with MIG.
2. Can you weld an exhaust pipe?
Yes, you can weld an exhaust pipe with almost every welding machine depending on its amperage output. If you have a heavy-duty welder, it might be not a good idea to weld such a thin material with this sheet. You can still get the job done with small spot or tack welds.
3. Is it possible to use a Stick Welder for an exhaust pipe?
Yes, it is possible but normally, the results are not much encouraging. It is better to use a 6011 rod with a stick holder to lower the chances of weld leakage.
4. Is it better to weld or clamp the exhaust?
Welding can provide you a much stronger bond than a clamp. This in turn affects the overall life of the exhaust. Moreover, it is not hard to weld before you attach the clamp, but it will make the job difficult once you did.
5. Can you use an ARC welder for exhaust?
In the case of an old exhaust, using an ARC welder will not have decent results. It will work to some extent but the weld will surely have slag holes and leaks.
