How to Choose the Best Stick Welders in 2021

The thickness of the Plate

The thickness of your plate decides the type of welder you need. It is always better to go for a welder which can weld a plate of more thickness than your usual one.

This margin not only gives a professional join but makes a room to weld even thicker plates if the need arises. Besides the thickness, you may also go for a wide amperage range as it will also open the doors for you to weld thicker plates.

Thermal Overload Protection

This factor protects your device from overheating. If a welder is incorporated with this feature, it gets automatically shut down as it starts to get overheated. 

This factor directly or indirectly affects the life and durability of your device. I would highly recommend this feature while you are searching for your perfect device. 

Single or Multi-purpose Welder

The single-use welder will exclusively do a particular task whereas a multi-purpose device will cover your other needs too. As a professional whenever I look for any device, I prefer a multi-purpose device like a flux-core welder with MIG or TIG capabilities.

Further, if are looking for a gas welder for clean welds, you may consider a welder that is capable to handle flux cored and fluxless wire. So, to save yourself from small investments, you may go for a multi-purpose welder as well.

Metal Thickness

The thickness of metals is a crucial factor which decides the type of welder you need. Like you generally deal with thin metals, flux core welder is an apt choice for you. Thus you need 130 to 140 amperes of current to weld metal with ¼” thick or less. 

However, if you are dealing with thicker materials of up to ⅜ inches of steel then you need over 200 amperes of output current. Also, for thicker materials, you should go for a MIG welder and at this point of time, the multi-purpose welder may save you.

Summing it Up

After all the research and reviews, I have selected Hobart 500559 Handler 140 as my best flux-core welder. The industrial ruggedness, outstanding quality and dual voltage make it an apt device for both beginners and professionals.

This welder has a wide range of options and id backed by a 5-year warranty too. You can consider other welders as per your requirements and future needs. Thanks for stopping by!
