[TheForge] Plasma cutter comparison

Thu Oct 30 23:35:01 2003

Try  http://harrisweldingsupplies.com/ for the hypertherm.

Their website sucks but their price couldn't be beat for a Powermax 1000.

I was looking at the 380 but decided to lay out the extra cash to have a
machine that would work well on a home made CNC table and cut thicker stuff
with.

Hypertherm does not use a high-frequency start.  A friend has an Esab with
the freaky start and it's ruined 2 fax machines and caused problems with the
phone and PC's.  His phone rings when the arc fails to start properly (when
it's on his CNC table).  That was the clincher for me between a Hyperthem
and a Thermal Arc brand.

Oh yah, the Cut master 38 does NOT use high frequency start either, I think.
Their bigger units do at the moment.  Here is the best price I found on that
one:

Take a look at the speed the 3/8 range cutters do for the thickest stuff you
plan to cut and make sure it's reasonable for what you want to do.  I think
it's typically about 10"/min for 3/8 material which is awfully slow to me.
