I was using the Hypertherm book settings .7 pierce delay, 40 ipm, 45a, 100psi. And I get decent results but alot of dross and bad taper on small holes. What settings do you use?
Do not have my chart with me now. I cut 1/4 at 40 amps and 50 ipm with my ht 65. Speed up a little. Set rule to slow down for small holes. What cam program are you using?
