How I Fix Hobart Welder Wire Feed Problems?
One of the most frustrating moments I have had in the shop was laying down a clean bead on sheet metal when my Hobart welder suddenly began feeding wire in fits and starts. The joint was clean and the arc…

MIG Welding 304 Stainless Steel: Wire, Gas & Settings (2025)
When I first tried to MIG weld 304 stainless steel, discoloration, porosity, and uneven fusion made the job harder than it looked. Stainless responds quickly to excess heat, poor shielding, and carbon-steel contamination, so your wire, gas, joint preparation, and…
How to Weld Aluminum with Flux Core Wire?
You cannot reliably fusion-weld aluminum with ordinary self-shielded flux-core wire made for steel. A gasless flux-core welder may work well on mild steel, but its wire, flux chemistry, polarity, and feed system are not designed for aluminum. The confusion often…
Flux Core Spatter: 7 Ways to Reduce Welding Mess
Flux core spatter can turn a short weld into a long cleanup job. A small amount is normal, but heavy spatter, loud popping, wire stubbing, or an erratic arc usually points to a setup, feeding, or technique problem. You can…
What Is the Best Gas for MIG Welding Mild Steel?
One of the first real challenges I faced in the shop was patching up a mild steel frame and realizing the biggest issue wasn’t the joint prep, metal thickness, or even keeping the arc steady—it was figuring out what shielding…
How to Weld Body Panels With Flux Core Wire Without Burn-Through
Welding a steel car body panel with self-shielded flux-core wire is possible, but thin sheet metal gives you very little room for error. Too much heat, a wide joint gap, incorrect polarity, or a long weld can quickly leave you…
Why Your MIG Welder Isn’t Working and How to Fix It
I can’t count how many times I’ve set up for a quick job, pulled the trigger, and found my MIG welder not working the way it should. The machine may be completely dead, feed wire without making an arc, sputter…
How to Use a Lincoln MIG Welder?
When I first got my hands on a Lincoln MIG welder, I quickly realized it wasn’t just about plugging in the machine and pulling the trigger. Using a MIG setup the right way makes all the difference between clean, strong…
Arc Welding Machine Problems and Solutions
One of the first lessons I learned with stick welding was that arc welding machines do not always behave the way you expect. An electrode may stick, the arc may cut out, the wire may feed unevenly, or a bead…
How to Weld Sheet Metal on a Car?
Welding sheet metal on a car is mostly a heat-control job. Thin body panels can burn through, shrink, or warp long before a bead looks finished, so success depends on choosing the right process, fitting the patch tightly, testing the…
