Picking The Best Multiprocess Welders

We all agree that buying a multi process welding machine will save you time and money. Many people worry that if they buy the multi-functional machine they will not get the same amount of power, or they will get fewer features that they can use during the welding processes.

When shopping for a multi-process machine consider the following things:

What do you want the machine to do?

Multi-process machines can have TIG welding elements, MIG welding elements, Flux-Core welding elements, and plasma cutters included in them. Think about the kind of welding projects that you are likely to take on with the machine. Then consider which welding process is best suited for that type of welding.

Will you be doing any fabrication? If you are doing any fabrication you are going to want a plasma cutter.

Once you have determined how you will use the machine the most you can decide which combination machines will serve you the most.

The Input Voltage and the Out Put Amperage

The input voltage will tell you what electrical currents you will need to have to power the machine. The common electrical circuit is a 110 volt or 115 volt circuit. These are the outlets you plug your normal household appliances like televisions, radios, small kitchen appliances, and computer in.

A 220 volt or 240 volt circuit is required for large appliances like dryers, electric stoves, some air conditioners, and electric water heaters.

If you buy a dual voltage device then you can plug it into either of these circuits. Your device will put out the maximum amount of amps when it is plugged into the 220 volt circuits, so read how many amps are provided when the machine is plugged into each circuit type.

What comes with the machine?

The manufacturers include different items with the machines they sell. Some manufacturers include the torches or electrode holder for every type of welding process the machine is capable of. Some will provide the torches for one or two welding processes. Make sure that you are getting the machine that provides the optimum amount of accessories.

What metals is it recommended for?

Each welding machine will have recommendations for the type of metals that it can be used on. Make sure that the metal you will use the most is included in the appropriate metals for the machine you have chosen.

Size matters

Technology is allowing these machines to be made smaller and lighter. Get a machine that will be easy for you to handle and move.

Special Features

There are a lot of special features that manufacturers include on their machines. Digital display screens are one of the favorite features. With a digital display screen it is easy to see the settings the machine is on, where dial settings are less easy to read.

It goes without saying that you want to buy a machine with a good warranty. You also want to read the reviews that other people have posted about the machine so you can see how well others like it.

FAQ on Multi Process Welding Machines

What is a multi-process welder?

A multi-purpose welder is a machine that can perform more than one job. Multi-purpose welders may be able to be used to do more than one welding process, such as TIG, MIG and stick welder combinations. These machines may also be capable of being used as a welder or as a compressor and in some cases, they can be used as a cutting torch.

What does a multi process welder do?

Multiprocess welder can often be used as a cutting tool to cut out the metal pieces you will weld, a welder, (possible it will do more than one welding process) and it may be able to be used as a generator to generate electricity for other tools you might use.

What is a 3 in 1 multi-process welder?

A three in one welding machine is a single machine that has the capability of doing the work that it would normally take three machines to do. The three in one might be able to do both MIG and TIG welding processes as well as be used as a generator to power tools. There are a lot of combinations that can make up a three in one multi-process welder.

Final Note

Buying the best multi-process welder means that you are investing in one machine that has the ability to function as three or more machines. If you read the details of the machine, and understand what the machine is capable of, then you should be able to buy a multi process device that will do everything you will want it to.

The technology that is allowing us to combine all of the welding types into one small machine, is increasing the features, and functions on the machines, while housing them in smaller and smaller packages.
