If it's the PowerMax 600 with the G3 torch, it's the lowest capacity in
the line, but hardly a bottom of the line unit. I have the PowerMax 1000
with G3 torch and it quite happily blows through heavy plate (rated 1"
cut, 1.25" sever) and is amazingly fast and clean on thinner material
like .125". The manual has charts of cutting speeds for different
materials, thickness and currents, intended mostly for CNC operation,
but still good to get some idea of how fast you should be moving,
typically faster than you think.
I've heard that you have a hard time getting air that is dry enough. I'm
using mine out in the desert where you can't spit on the sidewalk because
it evaporates on the way down. However, my compressor seems to have it's
air inlet somewhere near the Panama canal. Although I have been using the
cutter rather successfully, I'm told there is a marked improvement when
using really dry air.
Improvement both in cut quality, and more importantly, consumables life.
A lot of folks (including myself) are using the refrigerated air dryer
from Harbor Freight that runs around $300 or so depending on sales and
coupons. It's a decent unit, and a lot cheaper than other refrigerated
What Iggy said. It's just like any other cutting device. It has settings.
It has limits. It has parameters. It has peculiarities.
It is NOT the bottom of their line, and the cutter is better than about 95%
of what's out there. Take the time to learn how to use it. Get scraps and
practice different settings and thicknesses. It's a precision piece of
machinery, and does have a learning curve. Ask again after about forty
MAIN THING is use dry air! After that, RTFM.
