Both of those error codes are low inlet gas (air) pressure. I strongly suggest that you install a pressure gauge hard plumbed right at the air inlet fitting on the Powermax105. Read the pressure at this new gauge, then read the pressure at the source (compressor or regulator that supplies air to the plasma), they should read the same with no air flowing. Next, activate the air flow to the plasma torch (trigger the torch start signal momentarily...air will flow for about 20 seconds)....read both gauges again......you will see that the new gauge will read lower than the gauge at the source when air is flowing....this indicates a pressure drop in your plumbing system.....you may want to check the new gauge when the compressor is at its minimum output pressure (bottom of its on / off cycle) as well.
The Powermax105 requires 90 psi to 130 psi at the inlet when air is flowing at the torch. When inlet drops below this....even momentarily during a cut...the arc will be extinguished and an error code sent to the diagnostics screen. I suspect momentary drops in inlet pressure....could be caused by: too many filters, moisture traps.....or clogged filters/traps, could be too long of an air hose, or too small of an air hose inside diameter. Could be the regulator is simply set marginally low. Remember....check this with air flowing, and with the compressor at the bottom of its cycle.
Tech service at Hypertherm can help you with this as well.... Jim Colt Hypertherm
We have a 1 year old Vicon table. For the last week the powermax has been skipping/stopping cuts.
