Buyer’s Guide

Duty Cycle

The strength of your weld will be directly proportional to the duty cycle of the welder you choose. The smaller the duty cycle, the higher the quality of your welds will be, but you can’t get consistent results because you’ll only be able to make one weld per day. 

You’ll be much better off choosing a moderate duty cycle to avoid burns and excessive heat buildup. 

How Much Power Do You Need?

If you’re interested in a heavy-duty welder, you need to make sure you’ve got the right amount of power in order to ensure that you’re getting the best results. Here are some simple rules to consider when choosing a proper-sized welder: 

  • If you plan on welding large panels, like walls and ceilings, you’ll need a larger welder. But even if you’re going to be welding small metal pieces, like nuts and bolts, you need a bigger welder. 
  • Smaller size builds usually require a lower-voltage MIG welder, while larger size builds require higher-voltage MIG welders. The voltage used to weld small metal pieces is the same as the power you’d use to paint a house. 

When we talk about power, we are referring to the current that the machine uses when welding.

Does Your Job Require MIG or Is Flux-Core Enough?

The type of welding you choose to do can have an enormous effect on your life. If you’re working with metal, there are two main types of welding you need to be aware of: 

MIG (magneto-direct-current) welding

  • MIG welding is much less energy-intensive than flux-core welding, so it’s great for large projects that require lots of support 

Flux-core welding

  • Flux-core is excellent for small-scale projects because it’s much less energy-intensive than MIG

Every type of welder will require a certain type of metal to work with. If you’re doing plumbing, you’ll need a gas-operated pipe welder. If you’re making fence posts or staining cabinets, you’ll want a spot welder. If you’re doing metal art, you’ll probably need to use a flux-core welder.

Conclusion

Thanks for sticking with us to the end of our article about the best 140 Amp MIG welder, we hope you enjoyed it. Our champion of this competition goes to the Klutch MIG 140i. It has the right balance of power and ease of use everyone needs when welding. It will definitely do what you need it to.
