Do you have a Lincoln 225 Arc welder? Or are you planning to buy it? You will also need to get a good circuit breaker that is compatible with the welder. So, what size of breaker is ideal for this welding machine?

Read on as we have the answer.

Overview of Lincoln 225 Arc Welder

Lincoln 225 Arc welder is one of the most popular welding machines in the market. It is an AC/DC arc welder that can be used for both household and industrial purposes.

The Lincoln 225 Arc welder uses a flux cored wire to make arc welds on different types of metals like steel, stainless steel, copper, aluminum and more.

It has a high output power of 225 Amps and maximum voltage supply of 460V. The machine is equipped with a max duty cycle of 25% and a short circuit protection feature to keep the welder safe from any damage due to overload.

The machine weighs about 30 pounds, which makes it easy to carry from one place to another and store as well. The Lincoln 225 Arc welder comes with an Auto-Reverse feature that enables the machine to reverse polarity automatically without any interruption during welding process.

The Lincoln 225 Arc welder can be used for both AC and DC work and comes with an easy-to-use foot pedal for smooth operation. This machine also comes with a spool gun that allows you to use your own wire when making welds on projects at home or workplace.

This machine is ideal for welding small projects on thin metals like sheet metal or light gauges of pipes or wires etc. With this machine, you can perform TIG, MIG or stick welding according to your needs.

Circuit breaker size for the Lincoln 225 welder

According to the manufacturer’s manual, the right welder for a Lincoln 225 arc welder is 60A circuit breaker. This is the most recommended size as it will keep the machine protected from any damage due to overload.

If you have a smaller circuit breaker, you can still use it with the machine but you must be extra careful while using it as if the circuit breaker trips while you are welding, there is a chance of damage to your welder.

In order to determine the right size of circuit breaker for your welder, divide the nameplate current rating of your welder by 120V. This will give you the amperage required for your circuit breaker.

50A vs 60 A circuit breaker

When browsing through different welding forums, you will notice that some people are recommending 50A as an ideal breaker for the Lincoln 225 Arc welder. So, which one is the perfect size between 60A vs 50A?

First of all, take note that 225 welder comes in two sizes. These are 230 volts and 225 volts. Once you note these two sizes, you will be able to calculate the perfect breaker for the welder.

While the manufacturer recommends a 50 amp breaker will work perfectly for this welder. After all, the difference is very small to make any impactful change.

However, it is always to go for a higher-rated circuit breaker. It will offer better protection to the welders. This rule applies to most applications where you are torn between a small vs large circuit breaker.

What about the wire size for the Lincoln 225 welder?

Now that we have decided 60A is an ideal circuit breaker for this welder, choosing the right size of wire should not be a big issue. The #10 wires are mostly recommended for the welder.

However, there is a small chance that you will need to buy #8 wires. This is only because the manufacturer recommends a 60A circuit breaker with a #10 wire and not #8. So, if it happens that you need to buy #8 wires for your welder, then by all means go for it.

But I still use 30A breakers for my Lincoln breaker

Let’s face it, most houses still use 30 A breakers. So, what will happen if I use the 225 arc welder on with this circuit breaker? You will be walking on a red line if you choose these two combinations. The breaker will be constantly tripping in case of maximum power draw by the welder. Won’t that be too much inconvenience to your work?

So, what should I do?

The best solution is to upgrade your circuit breaker. This can be done by replacing your circuit breaker with a breaker that has a higher rating. You can also use a higher amp breaker, which will minimize the inconvenience caused by the tripping of the circuit breaker.

So, what’s my point here?

Upgrade your circuit breaker and you will have no issue in using the Lincoln 225 welder.

How many amps does Lincoln 225 arc welder pull?

This welding machine is designed to pull up to 40 amps. This is a good number because it allows you to use the machine to the optimum level. In other words, it will perform all the welding tasks for your project.

How can I tell that I have a genuine Lincoln 225 arc welder?

The Lincoln 225 arc welder has a serial number stamped on the top of the control panel. The serial number will be located in a red box, which is usually located at the back of the control panel.

You should also be keen on where you buy a Lincoln welder.

Buy a genuine 60 amp circuit breaker

As we have discussed, 60A is the right breaker size for the 225 arc welder. Your next focus should be ensuring that you get the right quality circuit breaker.

So, how can you tell that you have a genuine circuit breaker?

In order to be sure of having a genuine circuit breaker, look at the specification of the circuit breaker.

You should also consider where you buy the circuit breaker.

Buy from a recognized Lincoln welder sales outlet.

The Lincoln 225 arc welder is sold by authorized Lincoln arc welder dealers only.

This is to protect the customers against purchasing counterfeit products or parts that are not genuine.

You should also consider using a sourcing agent to help you with the purchase.
