Stainless Steel MIG Welding Settings Chart

If you have a project that involves metals you might have to use MIG welding. Although this welding method might not be for stylish pieces, it saves time and money. Besides, it promises also a great option for amateurs.

One of the ideal metals for MIG welding is stainless steel. But before you can make an incredible piece, it would help if you adjusted the welder with the right settings. For this task, you will need a guide that will help with the welder.

In this article, we have listed several settings for aluminum MIG Welding. So if you need a guide for working with stainless steel, scroll through this article and choose the ideal settings for your aluminum project.

Stainless Steel MIG Welding Settings for 0.23″ Wire Size ( 120 volt input) (Stainless Steel ER308/ER308L)

According to the chart, a volt setting of 18 is ideal for working with  0.35″ stainless steel. As for the speed, you can leave the speed on 234. But if you are working with 0.49″ stainless steel, maintain a setting of 20 and 256 for the volt/speed setting.

If you are working with a 0.30″ wire with 0.49″ stainless steel, you will also have to adjust the settings of the MIG welder. For this scenario, you can leave the voltage settings on 19 while the speed can stay at 234. However, working with 0.75 stainless steel means you should leave the setting on 21 and 234.

Stainless Steel MIG Welding Settings for 0.35″ Wire Size (120-volt input) (Stainless Steel ER308/ER308L)

Under this part of the chart, a volt setting of 21 and a speed setting of 190 are ideal for working with 0.75″ stainless steel. But if you are working with 0.49″ of the same metal, leave the volt and speed set at 19 and 234.

Stainless Steel MIG Welding Settings Chart for 0.45″ Wire Size (120-volt input) (Stainless Steel ER308/ER308L)

Does your MIG welding project involve 0.45″ wire size and .75 stainless steel? If yes you should adjust the voltage and speed setting to 21 and 190 respectively.
