Thick metals like ½ inch steel requires more heat to ensure that the weld is strong and sustainable.In order not to be deceived by false promises and marketing terms, it is necessary to know the minimum volt and ampere required. Welding 1/2-inch stee in one pass requires a minimum capacity of 250 amperes and 220 input volt to ensure smooth and correct penetration of the joints. There are many welders in the market that meet this “power” specification, but only a few are worth considering.
To make this most difficult task very simple, i want to introduce the best welder for 1/2 inch steel based on my research and tests. But to know them correctly, you need to look through the entire article. Hopefully, you will know them properly and obtain an appropriate welding machine.
Best MIg Welders for ½ inch Steel
After some tests that i made, I listed 5 welders that were best suited for 1/2 inch steel, depending on their pros and cons and characteristics. I also took customer feedback as a reference.
Here are the best mig welders for 1 2 steel
Eastwood 250 Amp MIG Welder Machine for ½ Steel & Aluminum
This powerful welder weighs 46 pounds and can operate on 120v or 240v, so it can be connected to virtually any existing circuit in the garage or store. It is the most advanced MIG welding machine available for 20 gage sheet metal up to ½ inch steel sheets. With an infinite adjustable knob, you can set amperes between 50 and 250 amperes, giving you greater control.
I have first tried this welder on dirty 1/4 inch aluminum after connecting everything and looking at the direction of the machine. Vertical Pass 2 inch length (amazing) even compared to stick welding (aluminum preheating) is very fast. This is a great performance, and the duty cycle is quite close to the rating. I used this machine to perform large welds over half inches in a spray arc, but it has never been overheated or protected. The aluminum spool gun is also wonderful.
Customers like the performance of this welding machine. Some customers mentioned in reviews Eastwood 250 Amp MIG Welder welds 20 gauge ½ inch thick steel, is easy to set up and can be used immediately. Some people highly appreciate the performance and quality of the welder. But most say it’s perfect even with little experience.
