    What air compressor CFM and reservoir size needed to run a 50 amp plasma cutter

    Thank-you, phaxtris! So, it sounds like: - I can find an online article, or even maybe a Youtube video on how to change from 120 volt to 240 volt, which eliminates the extra cost of an electrician - The ramp idea for unloading sounds doable. I might even be able to rent a small portable...

    Are 1/4" fittings different for welding gas cylinders than for air lines?

    Yeah, I hear you trevj. You are right about the proven easy way versus the experimental way. For example: I tried cutting my 3/16" thick by 3" wide aluminum flat bar using a Bosch jigsaw with a Bosch blade designed for aluminum, and got 3 decent 3" cuts and then the portion of the blade in...

    What air compressor CFM and reservoir size needed to run a 50 amp plasma cutter

    That compressor does offer some nice features: - Cast iron, like you said - Oiled versus oilless longevity - Sanborn is a longterm brand name - 75% duty cycle - Runs on 120V 15 amp circuit breaker circuit OR consumes 7.5 amps at 240 volts, so could run on my 20 amp 240 radial arm saw circuit...

    You are right about the post flow - I had not factored that in at all! That's a HUGE hidden loss. :( Jim G

    Are 1/4" fittings different for welding gas cylinders than for air lines?

    No, I was told that you can't use Argon alone. It is different to say that you CAN use it, but it will cause more slag AND will reduce your cutting capacity by 25%, and that this 25% reduction added to the 25% reduction already caused by cutting aluminum versus steel, would cut your cutting...

    Are 1/4" fittings different for welding gas cylinders than for air lines?

    Found the answer to my Argon question at: https://thebestcnc.com/what-is-the-role-of-the-gas-used-by-the-cnc-plasma-cutter/ In the quote below, the red font emphasis was by me: " Argon hardly reacts with any metal at high temperature, and the argon CNC plasma cutting machine is very stable...

    Are 1/4" fittings different for welding gas cylinders than for air lines?

    Well the last 2 postings give me pause. I was considering using Argon instead of a BIGGER and much costlier compressor than I already have for long plasma cuts cuts where my current compressor cannot handle the combinaiton of psi, CFM, and duration required. But ShawnR states that Argon cannot...

    What air compressor CFM and reservoir size needed to run a 50 amp plasma cutter

    Good points! Here are some of my responsive thoughts: The 2.5 max hp claim is marketing hype. When you open up the online pdf of the manual on the Princess Auto webpage, you see that the current requirements is only 12.2 amps. Startup would of course bump that up closer to the 20 amps available...

    Are 1/4" fittings different for welding gas cylinders than for air lines?

    Ok, here are photos of the 2 obviously different fittings: Normal quarter inch air male fitting, as found on my plasma cutter and my finish nailer: The Argon gas line male fitting on my Canaweld TIG welder that accepts the Argon gas line female Quick disconnect from my Argon cylinder...

    What air compressor CFM and reservoir size needed to run a 50 amp plasma cutter

    Princess Auto has this "silent" model: https://www.princessauto.com/en/20-gallon-portable-quiet-air-compressor/product/PA0008866642 The specs look impressive: 6.0 CFM at 90 psi 7.9 CFGM at 40 psi (Recall that my plasma cutter requires only 40 to 70 psi, depending no thickness being cut) 20...
