A 240v MIG welding machine will come in handy in industrial welding and remote sites where a standard 110v power plug is inaccessible. Also, this kind of welder will be useful for welding thicker sheets of metal.
So which is the best 240v MIG welder? After extensive research and testing, we have narrowed down our picks for the best 240v welder to three. The three listed below offered the best in terms of performance.
The Hobart – 500553 Handler, 210 MVP MIG Welder, is our top-ranking 240v welder. The LOTOS MIG175 175AMP Mig Welder follows it. However, all the other options on the list are still great welders.
best 240v mig welder With Reviews
Let Have a look at what each welder on our list has to offer.
Hobart – 500553 Handler 210 MVP MIG Welder
- Seven voltage settings

A dual voltage welder capable of running on either a 220v or a 240v power plug, the LOTOS MIG175 is not suited for home use. What is done for is industrial welding tasks that require more power.
This welder has an output of 175 amps, which is enough to weld up to ¼ inch stainless steel and mild steel. The welder also can weld aluminum and can handle welding 3/16 inch or thinner sheets of aluminum.
In terms of input power, it can run on either a 220v or a 240v power plug. Thus, there is no provision to run on a standard 110 or 115v power plug. However, this is not necessarily a bad thing, depending on your needs.
For working in remote sites, this welder can handle gas and flux core MIG welding. In our tests, we found the 0.35 flux core wire worked best. Coupled with the fact that it can weld steel, mild steel, and aluminum, it is a versatile machine.
As already mentioned, this welder can weld aluminum. And the best part is that it comes with a spool gun included. Also included is a 0.9 mm 1lb aluminum wire. Thus you do not have to purchase any additional accessories to weld aluminum.
The welder also has other accessories included, such as a ground clamp, gas hose, argon gas regulator, and a MIG torch.
- No need to purchase a spool gun for aluminum welding as it is included
- The machine can handle both gas and gasless MIG welding.
- It is powerful enough to weld up to ¼ inch thick steel sheets
- Can handle both standard 4 inch and 8-inch wire spools
- It is capable of running on both a 220v or 240 v power plug

Weldpro 155 Amp Inverter MIG/Stick Arc Welder
- 120v/240v input voltage
- 30-155 amps power output
- 60% duty cycle
- .023, .030, and .035 solid and flux core wire
- MIG torch and gun
The Weldpro 155 amp MIG/stick welder is a relatively small machine. This bright yellow welder measures 15 x 13.6 x 6.7 in and weighs 21 pounds. But its size and weight do not tell the whole story when it comes to the Weldpro.
The first thing that is evident from its name is that this is both a MIG and stick welder. Also, it can perform both MIG and flux core welding. To top it all off, you can perform TIG welding with a TIG torch that has to be bought separately.
So how much power can you expect from this unit? This welder has a dual input voltage of 120v and 240v. This means you can use it at home or in an industrial setting. In terms of output, it churns out a max power output of 155 amps.
With this kind of power, you can easily weld up to ¼ inch mild steel. The minimum power output stands at 30 amps.
Ready to use
Included in the package are several accessories that will come in handy. You get a MIG gun and torch, an electrode holder, cable, ground clamp, and a gas hose. These ensure you can get started with the welder right out of the box.

Best 240v welding machine buying guide
So what should you look for when buying a 240v welding machine? There are several things you need to consider when shopping for one, these are;
MIG and flux core capabilities
There are generally two types of MIG welding, gas and flux core or gasless MIG welding. The latter is suited to outdoor welding, while the latter is suited to indoor fabrication works. Some welders offer just one of these.
We recommend avoiding such welders and going for a welder capable of MIG gas and flux core welding.
240v welders will typically have different power output. A welder’s power output determines the thickness of metal it can weld. For example, to weld a 4.2mm or light gauge metal, you need about 165 amps of power.
On the flip side, to weld thin sheets of metal of about 24 gauge in thickness, you only need 24 amps. If you are welding thicker sheets, go for a welder with a higher max power output. A welder’s minimum outcome will determine whether it can weld thin sheets of metal.
How long a welder can weld before requiring a cooldown or duty cycle matters a lot. Ideally, you want a welder with a long duty cycle. However, the higher the output power, the lower the duty cycle. In this regard, a 30% duty cycle will be sufficient for most welding applications.
For low power output applications, the duty cycle can be 60%.
The best cheap 240v MIG welder will typically have the capability of handling more than one welding process. For example, the Weldpro 155 Amp Inverter MIG/Stick is capable of both MIG and stick welding.
This is important if you plan on doing more than MIG welding. Furthermore, the kind of metals a welder can weld matters. Some welders cannot weld aluminum. To be on the safe side, it is advisable to seek a welder that can weld aluminum.
240v welding machines tend to be more suited to welding thicker sheets of metal than thin ones. Therefore the best 240v MIG welder needs to be able to handle welding thicker sheets of metal. But still, be able to weld thin sheets of metal.
This can be through the welder being a multi-purpose welding unit. For example, a 240v stick welder can also be used for MIG welding.
Frequently Asked Questions
Q: How many amps does a 240v welder use?
Ans: A 240 v welder will typically use between 40 and 50 amps.
Q: What size breaker do I need for a 240v welder?
Ans: A 50 amp circuit breaker will be the best fit for the best 240v MIG welder under 500 or any other 240v welder.
Q: Can you run a 240v welder off a generator?
Ans: Yes, but the generator needs to be powerful enough. We are talking about 10kw of power from the generator to power a 240v welder.
Q: How do I know if my outlet is 240v?
Ans: A 240v outlet will be larger than a standard 115v outlet. A more definitive way to know is by using a multimeter. The latter can be acquired in most hardware stores. Set the multimeter to read” AC” and insert both probes into the outlet.
Check what the voltage that the multimeter is giving is. For a 240v outlet, it should read 240v.
Q: Can you plug a 240v appliance into a 220v outlet?
Ans: Yes, any appliance rated 240v can be plugged into a 220v outlet
Q: Can a 240v appliance run on 250v?
Ans: Yes, since the voltage listed is the maximum voltage, so it is safe to plug a 240v appliance into a 250-volt plug.
Q: What’s the difference between 220v and 240v?
Ans: A 220v is used for appliances that cannot be used with a 120v standard plug. On the other hand, a 240v plug offers more power and is used for larger appliances that require more power input.
