Bestarc Btc650dt Review : Pilot arc high frequency 

Great review I like how you do it. I had no idea that had the air feature in the front until I watched your video that is a game changer for me. My opinion that beats yes welder, Arccaptain, and all the rest. You should review some Everlast welders. I have the MTS 275 and absolutely love that machine.

Great video Ron! I have a wonderful Thermal Dynamics Cutmaster 81 but its high-frequency (HF) seriously affects the CNC controller for a plasma table I'm building. I had considered the Bestarc brand (sadly only available in HF) and had tried the 65A non-HF Yeswelder unit you previously reviewed, but I had to return it as the PCB mounts got broken in transit. I finally went with a CNC-ready 53A blow-back unit from Arcfony, the CUT-53N PRO, that I got for 400CAD.

I had my BTC650DP for a couple weeks now and curiosity got the best of me about the output. I put a meter around the ground cable, set the machine to 65 amps and cut some 3/8 plate. The meter only measure 50.5 amps output. I emailed Bestarc and they said that was the limit of the machine. No response on why they advertise it as a 65 amp model. Also at max air setting for 65 amps, my pilot arc will pulse on/off about every second (on 220v) no matter if I had the PA set for 3sec or 15 sec. It would work fine on 110v. Looking through the manual it states that a nozzle with a 3/64" orifice is good for 0-40 amps and a 1/16" orifice is good from 40-80 amps. The only tips that came with mine have a 1mm orifice (.039"). 3/64" translates into .045" or about 1.15mm. I ordered some bigger tips and the on/off pulsing of the pilot arc I had went away. I have yet to see if the stated voltage output is accurate. The fan eventually goes off too. With that said, It will still cut 3/4" plate "ok". Not bad for the $348 I got it for.

Would it cut through 1/2” AR500 plate? Are certain steels harder to cut through than others?

Hey man what happened to your samurai ?? Y No Moore videos

What breaker would you use ? -50 amp breaker on 220 or 65 Thanks

Another question - are you using an air compressor? If so what size Or a cylinder of air ? Thanks

The background music is way more annoying and louder than the fan was that you shut off so we could hear you.
