I am finally starting to cut some parts on my Dynatorch, after adding an air handler table (total plasma rookie).
In testing some 14ga test patterns, it seems that even though the Hypertherm 1000 can cut at more than 250ipm at 40A, the corners get real choppy at those speeds. I slowed it back down to around 160 - 170ipm to get a decent cut, but the dross seems to get worse the slower I go. I am just using the standard 60A consumables, and am surprised at how rough the edges are. More curf than I was expecting too. Sounds like I need the finecut consumables for the lighter (14 ga) steel? Does it work to run higher speeds but slow it down for corners?
In 7ga, it seemed to run OK at about 55A and 100ipm with a .065 offset, but again, more kerf and dross that I was hoping for. Any suggestions there? |
