I purchased a Yeswelder 65DS. I did this because everyone said to get a plasma cutter non-high frequency because the high frequency would cause problems with the 4X control box. So the hand held torch that came with the cutter works fine, however when I hook up a P80 straight torch to the cutter I get no spark from the torch. Any ideas? The torch that came with the cutter has more wires and maybe some kind of maybe a capacitor on the torch head. The P80 straight torch I purchased for this cutter does not have all the extra wires and the capacitor looking device at the torch head. Any help would be helpful.
All I can figure is the torch that came with the non-HF cutter has some kind of different HF torch head. The straight torch I purchased says non touch torch. Just totally confused.
If you take the nozzle off, does it have the same design as the hand torch? Blowback torches should have at least 1) spring pins contacting the outer copper nozzle (used to create the return for the pilot arc) 2) spring loaded electrode that you can push on (if the electrode doesn’t move its a HF) - that's what "blows back" through the pressure of the air on startup P80 vs IPT80 vs IPTM80 might come into play, not 100% sure myself, but if you look into it there are differences (plastic vs ceramic body, but possibly also different ignition types, etc)
From what I read the P80 torch requires a HF plasma machine only. Thanks for the help. I will try a HF plasma cutter.
Noooo that will cause a lot of EMI issues! Blowback is best! You have a good inverter, just the wrong straight torch. Just return and replace the torch with the P80s Blowback version (ask the vendor. Iptm80 or ipt80 or something like that - don't hold me to it, confirm with the vendor) HF is unusable around CNC equipment
What you suggest creates another problem. My plasma cutter uses a different connection for the torch. The first photo is the connection that my plasma cutter has and the second photo is the torch you suggested.
I have checked the 4x black box with a multimeter and the relay is not closing the relay. As far as using a high frequency plasma cutter I have been told to use a Clip-on Ferrite Ring Core RFI EMI Noise Suppressor Cable Clip on all the leads coming in and out of the control box to prevent any damage to the PCB.
HF won't work! Their high voltage high frequency pre-arc will trip up USB, HDMI, Endstops, even cameras. Its a 1950s technology still sold on the very lowest cost inverters only. Of course its your money if you do want to waste it to try an HF. But when it does damage the Blackbox you will be pointed back to this thread along with your warranty refusal. It is a bad idea. You will also be pointed back here when you ask for support because the HF is causing USB disconnects false alarms etc. You have been warned As for the relay, factory tested to work. If it does not, you either changed Grbl Settings or Relay Jumpers That Yeswelder Plasma is fine for CNC use. Just put in the tiny bit of effort to mount the hand torch, or find a suitable Machine torch (which does exist)
I totally give up. I am sorry I purchased a Table from Delusional Designs and your Black Box. There is no affordable solution for a home use cnc table or machine.
If this torch head will work I will give it one more try. Need your advice, this torch head with the yeswelder. 140A A141 HF pilot arc Straight Torch Head CNC Plasma Cutting | eBay
Probably unlikely - 140A is way outside the range of the 65A Its also bare, no plumbing included etc which complicates issues again finding the right threaded adapters etc Why not just mount the hand torch that you know works? All the extra complications are just causing you frustration. You don't need a machine torch, just make sure to mount the hand torch nicely: And no, you don't need a 3D printer. Baling wire, hose clamps, epoxy putty, wittled piece of wood - just fashion a way to hold it a close to upright as possible. Another random screenshot off youtube (bolts and hand cut plate - apply some imagination ) Once its up and working you can use the machine to cut a better mount for itself and upgrade as you go. If you insist on a machine torch, you would have to find a torch supplier you can actually talk to and explain what fittings and wiring it needs, what amperage range, blowback style etc so they can get you the right one. Online pictures are misleading, you'll end up wasting money
Thanks for the suggestion about mounting the hand head torch. The problem is the head length is too short. I did cancel the 140A head because it required HF machine. I am conversing with the Non-HF torch head manufacture, he has suggested the 60AMP non-HF torch , pictured. Also is the hand held angle torch that came with the machine.
