Just went to a demonstration today of their 80 amp unit on a plasma table. I wasn't particularly impressed. Hypertherm touts its long life consumables, and the consumable didn't even make it through its first 8 ft linear cut on a new table. The techs were mumbling a lot about issues they were having with some things. I am going back tomorrow to see part two of the demonstration so I hope things improve. I know what I have heard about their units have been wonderful, and glowing, but it was struggling to cut 3/8" plate on a 42 degree bevel, around 2 feet per minute cutting speed, and they had to increase pierce delay time to around 4 seconds. Not to discourage anybody from purchasing, one, I was considerably taken back by its performance, since, many people have given such high marks....I was expecting much more performance, after having used our units for so long. I think if they figure out the roasted consumable issue, things might work better. I am sure there is some reason this happening. But as soon as the techs saw the problems, they started making all sorts of excuses about the quality of the air supply and other issues that caused it, but several other Millers are in use around the shop and the tanks is drained daily and high quality dryers are used on the line... It may also have been from the settings within the CNC table. But it was shooting a steady shower of sparks while the pilot arc was engaged.
