    First "lunchbox size" plasma cutter experience

    I AM going to experiment with psi, amps, and feed rate. I have been Googling info on those parameters since my last posting, and am finding that the recommendations differ WIDELY from manufacturer to manufacturer. When I say "widely" varying recommendations, I mean specifically the feed rate...

    First "lunchbox size" plasma cutter experience

    I thought I had screwed up in my uneducated choice of psi and amperage combination. Are you saying that the cut in the photo I showed is what I should expect for 3/16" thick 5000 series Aluminum?? Jim G

    First "lunchbox size" plasma cutter experience

    All great ideas! Thank-you! I id try cutting some 1" square aluminum tubing with 1/16" wall thickness on my woodworking bandsaw, and it worked fine! That produced and left some fine aluminum particles on the bandsaw and its stand, but almost no noise compared to a circular saw! I will try...

    First "lunchbox size" plasma cutter experience

    I just received and tried out one of the inexpensive "50-amp" lunchbox sized plasma cutters, and I have to say I am somehwat impressed, even though my initial "technique" is inexperienced and undeducated. The unit i have is the BestArc Pilot Arc BTC500DP 50Amps Dual Voltage 110/220V unit. This...

    How estimate rate of Argon gas consumption when TIG welding?

    One thing I really like about pure Argon is that it is 38% heavier than air, so ventilating it entirely would just require opening my garage car door. And actually, at 15 CFH usage, there will never be enough of it to pose any asphyxiation danger to me. It's also non-reactive. The Argon -...

    What am I doing wrong?

    Good news! The new robust ground clamp solved the "occasional no arc" issue. And it is also more compact and easier to use than the clamp that came with the TIG welder. However, I have a question: The new clamp, like the majority of quality ground clamps has a threaded screw that is tightened...

    How estimate rate of Argon gas consumption when TIG welding?

    Actually, I am anticipating welding primarily .06" to 0.25" aluminum, and .06" to .125" stainless steel. I am finding in my training lessons that with the .19" aluminum coupons I am using, I START the pool at 150 amps but quickly have to throttle down to prevent overheating the material, so I am...
