Welding Samples

By Cole Rutkowski

Here are several sample welds I produced in the fall of 2026 as practice for a mountain bike frame I am building. I primarily practice with .035" 4130 chromoly steel, but I am starting to dabble with .125" plate steel and .125" aluminum plate. I have tried various setups, but right now I have been having success with a #10 cup and pulsing at 1-1.5hz, 40% peak time, 40% background amps.
