How to Buy the Best Multi Process Welders

Photo: Lincoln Electric

The following paragraphs show you how to check and select the best multi process welders. Understanding these features should make your life and job easier.

1. Power

Different welders use different types of input power to produce other types of output power. So, the multi process welder that you select has to come with a power source system that you can easily get.

For example, some welders have DC inputs, while others use AC inputs. There are also voltage differences, with some welders depending on 120 Volts, while others need 240 Volts, plus many like the Lincoln Electric K419501 can handle both.

You need to check these features before making your choice to make sure you can find the power source that the machine needs.

2. Primary Function

Another issue you should keep in mind is that although multi process welders enable you to work with different welding systems, many of them have a primary function, especially MIG welding.

You must understand this because you’ll work better if most of your work is also the same as the machine’s primary function.

Some multi process welders work beautifully in all their different working modes, but these are often the better-quality machines.

3. Material & Welder Amperage

The materials you will work with will also help you choose the best multi process welder for your shop. This includes the material’s thickness, for instance, which determines the top welder amperage you should get.

For most DIY jobs anyway, a 150-Amp maximum output is usually enough, while you may need a more powerful machine above 200 Amps for automobile repairs and so on.

If you’ll be TIG-welding aluminum, then make sure there’s AC output on the machine, because a typical DC TIG welder won’t work. Aluminum TIG-welding needs current pulsing to work and that’s what an AC output offers.

4. Budget & Build Quality

One advantage of multi process welders is their lower cost compared to buying different welding machines, so the budget is also important here.

You’ll find the best multi process welders ranging from hundreds of dollars to a few thousand dollars in price, so set a budget that you can afford and then work with it.

Keep in mind, however, that the better-built machines often last longer, come with longer warranties, but also cost more. So you also need to find your balance here between quality, warranty, and price.

5. Ease of Use

A multi process welder is a complex machine, but this doesn’t mean it needs to be complicated. The best multi process welders and plasma cutters are intuitive and easy to understand and use.

You should go for a machine that offers digital displays, if possible. Simple but precise controls are also important. And startup and process change should happen in as few steps as possible.

6. Portability

You’ll get multi process welders in slightly different sizes and with different handle designs for improved portability. But, the major issue with them is their weight.

Multi process welders are on average, heavier than ordinary welders. So, you need to monitor the weight of any machine you’re considering. You can also consider getting a good welding cart if you think it might make your life easier.

Conclusion

We’ve come to the end of this multi process welder reviews and you’ve seen the top offers out there in the market, including the budget offers and the top of the line models such as the Miller Electric 907757.

If you’re in a hurry, you can go for the best overall machine here or the best budget option. Else, you can also take your time to choose from the list.
