WSS,
I am sure you are ready to see the sparks fly! I am anxious to hear how it all works out.
Thanks for the info and link. I am very interested. Is the chem etch what you normally see on the blades of most knives these days?
I have the 1250 hypertherm so I need a different chart than the 1650. Since I do alot of thin material I also want to make a chart for finecut consummables.
I know you have already checked the ground for your table and Dynatorch has their own method for doing so in their manual but there is something I wanted to pass along to everyone that happened to me.
In the Dynatorch manual they state that you should consider drilling a hole in the floor near the machine and drive in a ground rod so as to get a good ground for the machine. I did just that when I installed my table however after conducting their ground test on the new 5' deep ground rod it failed terribly. My first thought was how could this be? Perhaps I must have made some kind of mistake in the test. I checked 2 more times, same result?
After consulting with my electrician he informed me that the moisture in the earth has alot to do with with how good of a ground you get. He recommended that I run some water down around the rod to help it. My building was built in 1982 so after 27 years the soil beneath must have been plenty dry. I was'nt to keen on this as it would have required drilling another hole and the water would have had to seep at least overnight.
I ended up buying a roll of 1/4" diameter copper grounding rod and running it to the existing ground rod for my buildings electrical box. It then passed the ground test with zero problems. It made me realize that a ground can change over time and just because you have a 5' ground rod driven in the soil does not mean you have a good ground and it should be checked periodicly. It is cheap insurance against pontential electronic damage.
