The first time I tried using gas MIG outdoors, the wind disturbed the shielding gas and left porosity in the weld. That experience showed me why many welders want to convert a gas MIG welder to gasless flux-core operation for…
Cleaning galvanized metal before painting is more than wiping off dirt. You need to identify the type and condition of the zinc coating, remove oil and loose corrosion products, create only the amount of surface profile the coating requires, and…
Shielding gas prices vary by supplier, cylinder size, ownership plan, and location, so there is no dependable national refill price. The most useful number is your cost per cubic foot, followed by your cost per hour of gas-on time. This…
Struggling with arc stability on stainless sheet metal can be frustrating. Even with clean joints, correct filler metal, and steady torch movement, the arc may wander, the tip may overheat, or starts may feel inconsistent. The tungsten electrode is often…
Flux-cored arc welding is often the process people reach for when a steel repair is too heavy for thin-sheet methods or the job must be done outdoors. I first understood its appeal on a thick trailer-frame repair: the wire fed…
I’ve lost count of how many times I’ve walked into the shop, ready to weld, only to find the steel covered in rust. Light surface rust does not always make a weld impossible, but it does make the job less…
When I first started using a Lincoln welder, I expected the settings to be simple: choose the metal thickness, turn two knobs, and start welding. In practice, voltage, wire-feed speed, amperage, polarity, shielding gas, filler metal, joint design, and travel…
I tried welding on a flimsy workbench that wobbled every time I struck an arc — and believe me, nothing kills your weld quality faster than chasing stability while trying to control your puddle. That’s when I realized a solid,…
When I first started running beads with stick, one of my biggest headaches was finding the right amperage for each rod and metal thickness. Too little current made the electrode stick and sputter. Too much flattened the puddle, increased undercut,…
If you’ve ever pulled off your hood to find tiny holes pockmarking your weld bead, you’ve likely encountered porosity in arc welding. It’s one of those frustrating defects that can turn a solid weld into a weak, unreliable joint. As…
