Feature Description
-17 Wire Jogging The wire jog setting has been eliminated from the softswitches, but is still
available in the lower display of the Preflow screen.
NOTE: Quickly cycling the inch button with a high wire feed speed may cause
the current protection circuit to trip. To reset the protection circuit, cycle power
on the HMC-410. To avoid tripping, program in a lower wire feed speed or don’t
re-hit the inch button so quickly
17+ Fixture 2 Relay 2 will close at the end of any weld, not just between spots of a stitch weld
Relay and after a continuous weld.
Operation
17+ Error Relay The Error Relay and Error Light will both operate whenever there is an error
Operation condition (loss of arc, out of tolerance, ground fault, or current error). The Error
light will stay lit until another weld is started, or power is cycled. The Error Relay
will stay closed from the time the error is found until .5 seconds into Ready
mode. At that time the relay will open, so if it is desired to have this condition
latched on for a longer period an externally latched relay should be used. The
ground fault relay is an exception to this, it will remain latched until power is
cycled. Note that this will result in the condition that the Error light can be lit
while the Error relay is open.
When using the Debug feature, these same features apply except for the Error
Relay opening up. The Error Relay will remain closed while the Debug screen
is displayed. The Error Light will remain on until the next weld is initiated. When
the error is cleared (by pressing Cycle Stop), the system will leave the Debug
screen and turn off the Error Relay. In any case, the Error Relay will stay closed
for at least .5 seconds.
17+ Password The user’s password is programmed into UPS. The supervisor’s password is
Operation programmed into SPS. If the UPS matches the SPS, then the authority level is
only WELD, regardless of the setting of the keyswitch. Also, if the UPS number
does not match the SPS number when entering the softswitch screens, the user
is only allowed to program the UPS value. Thus, the user may not edit any other
softswitch screens unless he powers up with the UPS and SPS set the same.
17+ Enhanced Added END function to sub segments. Now, subsegments will automatically
Sub Segment sequence from 1 to 2 to 3 to 4 based on times (ie, the whole sequence is
Operation continuous). By programming END into subsegment times (subsegments 2 to
4), the sequence will exit to craterfill. Thus, now we can have 3 start phases,
and perform a continuous weld in the 4th subsegment. Recycle may be used if
the sequence exits based on ‘END’ programmed into the subsegment timer.
The subsegment advance pin found on the auxiliary interface may be utilized
for front panel or remote pendant initiated welds.
20 External The 171238-20 software allows the 410 to utilize externally generated voltages
Control to control the wire feed speed and arc voltage (pulse frequency) functions of
the power source. These features are normally used in conjunction with the
870236 Robotic Interface Kits. In order to utilize the external voltages for any
phase of the weld, simply program in EEE (for external) where the wire feed
speed or arc voltage setting is normally entered. For that part of the weld, the
external voltages will then set the wire feed speed and / or arc voltages as
programmed.
