PRM04 – POWER 1
The value expressed in the POWER 1 parameter indicates the power used to carry out the pre-weld.
PRM05 – COLD 1
The COLD 1 time parameter indicates the time that elapses between the PRE-WELD and the WELD.
When the pre-weld is off (PRE-WELD time equal to 0) this cold time is not carried out.
PRM06 – SLOPE UP
The SLOPE UP parameter describes the time during which the programmed weld current is reached. The initial
value of this slope is always equal to the minimum current whilst the final value is equal to the current value
programmed in the POWER parameter. The microprocessor calculates this slope automatically, according to the
programmed values. The SLOPE UP time is added to the WELD time.
PRM07 – WELD
The WELD time parameter represents the duration of the weld current flow. The weld will be carried out at a
power value equal to the one indicated in the POWER parameter. When the impulse mode is activated, this
parameter indicates the duration of every single impulse.
This parameter is expressed by three digits since it can be adjusted with the precision of a half period.
PRM08 – POWER / CURRENT
Depending on the adjustment mode selected via the WORKING MODE parameter, the PRM08 parameter can
assume the POWER or CURRENT
values.
When the WORKING MODE parameter is adjusted to PW% (Power) or ENE (Constant Energy), the POWER
parameter appears. Its value indicates the power percentage adjustment with which the weld is carried out.
When the WORKING MODE parameter is adjusted IK (Constant Current), the CURRENT parameter appears.
Its value indicates the current adjustment with which the weld is carried out.
PRM09 – IMPULSE N.
The IMPULSE N. parameter indicates the number of impulses used to carry out the welding process. The
duration of each impulse is that set in the WELD parameter.
PRM10 – COLD 2
The COLD 2 parameter is used in the pulse operating mode; it indicates the time that elapses from a welding
impulse to the next one.
When the impulse number is set to zero, the cold time 2, even if programmed, is not carried out.
PRM11 – SLOPE DOWN
The SLOPE DOWN parameter is a weld time that is reached at the end of the welding operation and during
which the welding current decreases to minimum by the amount set in POWER or in CURRENT. The
microprocessor calculates this slope automatically, according to the programmed values.
The SLOPE DOWN time is always added to the WELD time.
PRM12 – COLD 3
The COLD 3 parameter indicates the time that elapses from the WELD time to the POST-WELD time.
PRM13 – POST-WELD
The POST-WELD time parameter describes the duration of a current flow that can be carried out after the weld
time. If the parameter is set to 0, the post-weld will not be carried out. It will be carried out with a current
adjustment equal to that indicated in the POWER 2 parameter.
PRM14 – POWER 2
The value expressed in this parameter indicates the post-welding power.
