For welders, makers & the home workshop
Learn how the MIG process works, how its components fit together, and how technique and setup affect your results.
Getting your shielding gas flow rate wrong is one of the most common — and most overlooked — causes of poor MIG welds. Too little gas and you get porosity.…
Continue reading: How Many Litres Per Minute for MIG Welding?If you’ve just set up a MIG welder or you’re troubleshooting poor weld quality, polarity is one of the first things worth checking. Getting it wrong doesn’t just affect your…
Continue reading: Is MIG Welding Positive or Negative?MIG welding requires the right shielding gas to create strong, clean welds and protect the molten metal from atmospheric contamination. Choosing the correct gas affects weld quality, penetration depth, and…
Continue reading: What Gas Do You Use for MIG Welding: Complete Guide to Shielding Gas SelectionMIG stands for Metal Inert Gas, which is a welding process that uses a continuously fed wire electrode and protective inert gas to join metals together. Also known as Gas…
Continue reading: What Does MIG Stand For? A Complete Guide to Metal Inert Gas WeldingDialing in the correct MIG welding stainless steel settings is where most welders start running into trouble, especially if they’re used to welding mild steel. Stainless reacts differently to heat,…
Continue reading: My MIG Welding Stainless Steel Settings That WorkMIG welding 304 stainless steel looks straightforward until you actually start running a bead and realize it doesn’t behave like mild steel at all. In the shop, I’ve seen plenty…
Continue reading: MIG Welding 304 Stainless Steel: Tips for Clean, Strong JointsOne of the first technique questions that comes up with MIG is do you push or pull when MIG welding, and the answer can make a big difference in how…
Continue reading: Do You Push or Pull When MIG Welding? A Shop-Tested GuideChoosing the best gas for MIG welding mild steel is one of those decisions that quietly affects everything—from how smooth the arc feels to how much cleanup you’re stuck with…
Continue reading: Best Gas for MIG Welding Mild Steel (CO₂ vs Argon Mix Guide)There is no single amps-to-wire-speed multiplier that reliably sets every wire-fed welding process. Wire classification, diameter, stickout, polarity, shielding and equipment all affect the operating point. This tool provides discrete…
Continue reading: Wire Feed Speed Calculator and FormulaMIG welding aluminum with a spool gun can be both a game-changer and a challenge, even for experienced welders. Aluminum behaves nothing like mild steel—its fast heat transfer, sensitive metal…
