4.07 SAFE MODE
SAFE (Special Application Function Environment) is a mode of operation that the 400MSTP of welding
power source can enter in order to customize the welder for a special application. In most cases this
power source feature can be ignored. The factory default settings are expected to be sufficient for most of
our customers. In the few cases that the factory default settings are not adequate, the 400MSTP can be
programmed to meet special specifications.
There are two separate safes, one for single phase operation and one for three phase operation. These
safes are independent of each other, and are accessed automatically when the machine is powered up in
either the single or three phase mode. Any changes to one will not affect the other.
The following parameters are programming in the SAFE:

RESET THE SYSTEM. .
This option resets all SAFE parameters to their factory default
setting. "no" means do not reset the system to factory default
while "rES" means reset the system to factory default settings.
Only the single phase settings will be reset if the machine is
hooked up to single phase power. Likewise, only the three
phase setting will be reset when hooked to three phase power.
NOTE: THE SAVE BUTTON MUST BE DEPRESSED WHEN
EXITING THE SAFE MODE IN ORDER FOR THE RESET TO
OCCUR.

WIRE SHARP VOLTAGE SETING. .
This is the voltage that will be present on the wire following a
GMAW or Pulsed GMAW weld. This feature "sharpens" the wire
by burning off the ball of filler metal that often forms on the end
of the wire following a GMAW weld. The voltage can be set to
any value between 0 and 20 volts in increments of 1 volt.

WIRE SHARP TIME. .
Wire sharp time is the length of time following a GMAW or
Pulsed GMAW weld that the wire sharp voltage will remain on
the filler wire. This variable time is adjustable between 0 and 1
second in increments of 0.01 seconds. Longer times will give
more of a burn back effect.

MAXIMUM SELECTABLE AMPERAGE. .
Maximum selectable amperage is the largest amperage value
that the user is capable of setting in SMAW, Lift GTAW, or
GTAW local mode. This feature is effective when the user would
like to insure that the amperage is never set above a particular
amperage level. The range of values permitted is 5-275 amps
(single phase) and 5-400 amps (three phase). The maximum
selectable amperage is never permitted to be set less than the
minimum selectable amperage.
