Primal Decals 621 Posted January 5, 2018 So , on another forum im part of , the question came up " what psi are each of the numbers on the dial"? Nobody could figure out what the conversion was till i contacted a Tech at Stahls. So for every dial number 1-9 on hotronix press is 10 psi. 1 = 10 psi 2= 20 psi 3=30 and so on.... The reason this came up was someone had bought some material and the specs for pressing was in psi. And on hotronix they use #s 1-9. Hope this helps anyone that ever got curious or didnt know. 4 Share this post Link to post Share on other sites
