HELP WITH THC

Postby tdalechick » Fri Dec 26, 2014 6:31 pm

I am having problems with my torch dragging across the metal almost breaking it off before I hurry and hit the stop button!! You guessed it I have a Burn Table. I haven't had this issue before and it has been working great until I went to cut 10 ga and have switched the sheet cam back to 14 ga now it has been cutting horrible. Now the torch is dragging. Just tried moving my ground to the metal itself thinking it was getting a bad ground well it just did the same dragging and almost broke off so that is not the problem. Just reset all the settings in sheet cam to what was recommended by burn tables. Any other help out there would be appreciated it. I have a huge order and need to get started while I am off this weekend and burn tables is closed and they answered my email and gave me settings but turning that knob is not helping getting the torch moved up where its not dragging while cutting a 3 inch square... I am using a Hypertherm 45. If anyone could help me please let me know. Thanks Cassie

I don't have a BT but have you tried turning off the THC and just manually setting the height so that it will cut? May get you through the weekend.
Also i would look into a magnetic torch holder in the future. If the torch drags it pulls off the holder and shuts everything down. No chance of breaking a $$$$ torch body.

I will give that a try just to see if it will cut.... Where do you look into the magnetic torch item at? may need to check into this. I almost think it may be the control box but hoping its not.

Did you get your problems figured out?? Just curious what the solution was. I have a Powermax 85 and a 4x8 Burntable. My THC has been flawless once I got it dialed in. Took me a little bit to get it figured out since I am new to the CNC plasma world. Let me know if I can help.

You're right, the BT torch holder is a piece of $#!!^. I ended up making one out of aluminum which was a little heavier then the delaminated plastic crap part but as a bonus I got rid of the highly engineered bungie cord :roll: .
The torch height control is total crap but unfortunately I have to fight with it as the slats are an inch higher on the left front of the table compared to the right rear.
My problem is opposite of yours, I can never get the torch close enough to the plate to get a decent cut. The best I can get for a torch height is a quarter inch off the plate even with the "Knob" rotated right just off the left stop. Putting up with crappy cuts and grinding dross until you blow black snot boogers :o is better than having an expensive POS sitting in the shop collecting dust instead of making some.
Now for some tips that MAY or may not help,
I do have to play with the THC percentage quite often for different steel thicknesses (could be more of a cut speed difference, I'm not sure) and if cutting artsy stuff you will be adjusting it even more. I also had to play with the THC speed. I turned it up until it gave me a bad bounce then back it off to prevent oscillations.
If anyone is keeping track you can put another tick mark next to the "Unsatisfied customer" for Burntables.
