stiff plasma torch cable

admin

Now that I'm doing the semi retired thing

my ol Miller Spectrum 2050 Plasma hasn't been getting used as much as it used to, I went to set it up the other day and the torch cable is so stiff it won't unwind, several sites say to soak in brake fluide has anyone tried this on welding cables? any other ideas?

Reply:I wonder if UV’s affected it?I wrap my plasma torch cables with hydraulic spiral wrap for protection from mechanical damage.

Enjoy the new chapter of your life.  I took early retirement to raise my young daughter (ten years ago) and don’t regret a day!Sent from my iPad using Tapatalk:

Reply:Tagged stiff plasma torchI have the same issue with my Hypertherm Powermax 600."Where's Stick man????????" - 7A749"SHHHHHH!! I sent him over to snag that MIC-4 while tbone wasn't looking!

Reply:Slightly unrelated but I absolutely HATED the light gauge ground/work cable Miller and Hypertherm provide on their under 100 amp plasma cutters. Virtually impossible to wind up neatly when done. Same for the voltage sensing cables for wire feeders. I upgraded mine to 6 gauge wire which is WAAAY more flexible.

But then I got really smart (well smarter) and used aforementioned hydraulic spiral wrap and integrated the ground and torch cable together.

Reply:That is normal for the older torch's used on Hypertherm plasma cutters. The air hose is nylon and gets really hard and trying to straighten it will crack the air line and if you run soapy water over the cable it will bubble. Best thing to do is buy a new duramax torch that will fit the plasma cutter.www.georgesplasmacuttershop.comPlasma Cutter and Welder Sales and Repairs--Ebay storeTec.Mo.

Reply:What we really need is to get get on CKs case to build us some superflex cables like they use on their tig torches.I emailed hypertherm about buying just the threaded ends and another plastic plug and they were real uncooperative about it. They told me I cant modify it, well if they dont want it modified there going to have to build it better....

Reply:Theres hardly any flow, a superflex cable will be fine.The plasma cable is under pressure, lets say 6 bar.That means the flow is 6x slower inside the cable because the pressure drop is at the nozzle
Reply:This is really not true. You must use a hose of the same size that will not expend/swell and has the same flow rate as the factory hose or it will not work properly. Mainly this is for the pilot arc to work. This is only on blow back plasma cutters. High frequency plasma cutters does not matter as much on air line size.www.georgesplasmacuttershop.comPlasma Cutter and Welder Sales and Repairs--Ebay storeTec.Mo.

Reply:Lis2323, now we're gonna have to talk bout your timing with puttin out the pics!! LOL! I already bought (and installed) the hydraulic protective cover that just fit my torch cable... now that adding the ground cables a great idea... but ya were a lil too slow sharin it!

Reply:Hydraulic shops usually have a homemade winder setup to turn the hydraulic hose and feed the wrap. No way to easily do it for torch hose setups unless you disconnect the torch (Mig or plasma). Even then it may get dicey.  Believe me I've tried.
