I finally got the hang of the Dynatorch the other night, and made a slew of rookie errors getting there.
For the work I was doing, I needed a Fine Cut 45A nozzle and shield set, but couldn’t find them in the Metal Shop. All I could find was an 85A Set. So, like a genius, I reasoned that I should just lower the current so it wouldn’t blast my piece to smithereens. THIS DOES NOT WORK! The nozzles will gaul up with splatter and freak-out the Ohmic Sensor, requiring repeated disassembly and cleaning. Also, the Ohmic Isolator and Shield (the one with the melted tab) weren’t connecting. Luckily there was another set there.
To try to remedy this situation, I ordered-up 5 sets of Fine Cut nozzles and shields from Jack&Dave on Amazon (has anyone used Jack&Dave consumables here?), they arrive today by 9pm. I also got 5 new electrodes. The plan is to leave 3 of the sets in the Metal Shop for anyone to use. I hope they don’t vanish like the rest of essential consumables.
As a reminder, with the exception of welding gas/wire we do not provide consumables in the metal shop. I do not expect those consumables to last / avoid growing legs. We lock up the teaching and committee fine cuts.
Most of us just maintain a little tackle box or similar with the various consumables for the different types of torches.
Mitchell Welding Supply. I picked up a heat shield, a 45A fine tip, and electrode since the teaching box was out of 45A or doesn’t stock it. Seemed not excellent to use tips for amps I am not used to working with and destroy them. Literally one of each. My husband said it was about average so I just kinda accepted it since copper has gone up a ton since I last bought plasma consumables.
I was going to get some glasses too but they wanted $10 to $15 a pop .
Check me if I’m wrong; but we need a nozzle and shield to change current and fineness. The electrodes wear out, so I got them too. The swirl and Ohmic standoff are universal, and don’t wear out nearly as fast. Is this correct?
