The Transfer signal was
lost before the Arc Glide
removed the Plasma Start
signal from the plasma
system.
This error occurs when
cutting scrap and running
the torch off the edge of
the workpiece.
The Transfer Height or
Pierce Height is set too
high.
The lead-outs are too
long, especially when
cutting holes and the arc is
stretching out as the slag
falls into the table.
There is a faulty connection
between the work piece,
the cutting surface, and the
work lead of the plasma
system.
There is a damaged
or loose work lead
connection on the plasma
system.
A loose connection or
damaged plasma interface
cable.
Check the plasma system for errors.
Check the transfer height (or pierce height) setting in
the Plasma Process screen or in the plasma menu in
the control module.
Do an IHS test and verify that the torch is retracting
to the pierce height listed in the plasma system cut
chart.
Check the torch consumables for damage. If you are
cutting scrap, this error is normal but will reduce the
consumable life.
Check the lead-out length, especially if you are
cutting holes.
Check the EDGE Pro Arc Off time. A small time
should be used, 0.1 at the extreme.
An Arc On time that is too high may prevent the error
from occurring but could result in poor consumable
life.
Verify that the arc is shutting off over metal.
Verify the bonding of the workpiece, table’s surface,
and work lead connection to the cutting table. Sheet
metal or heavy slag build-up on slates can result in a
poor bond between the plasma arc and the work lead.
Check the plasma system’s work lead for damage or
loose connections.
Check the plasma interface cable for damage or
loose connections.
