ITEM TE700
TECNA
S.p.A.
56/128
PRE-WELD
When set to ON it activates the pre-weld parameters in all the programs.
POST-WELD
When set to ON it activates the parameters relevant to the post welding, the cold 3 time and
the slope down in all the programs.
WELD 2
When set to ON it activates the welding 2 parameters in all the programs. If the WORKING
MODE of a program is set to DYNAMIC, the WELD 2 parameters in that program will not be
activated.
DYNAMIC TIME
This parameter allows the operator to set the time window inside which the DYN WORKING
MODE can intervene to correct any welding defects. The intervention time may be adjusted
from twice the time required to carry out the sample weld up to 9 times the time used to carry
out the sample weld. If the DYNAMIC control unit is not capable of correcting the error within
the max foreseen time, the control unit stops and signals the error (see the specific chapter).
DYNAMIC COMP
This parameter allows the operator to set, with DYN WORKING MODE active, how effective
the action of the weld correction algorithm should be. When using the machine under routine
conditions this parameter should be set to 30%. Increase the value of the parameter if the
corrective action is not satisfactory.
WELD QUALITY
This parameter allows the operator to activate additional weld quality controls inside the weld
program. The operator may choose to activate either the measurement of the initial and/or
final resistance quality or only the measurement of the initial thickness and/or penetration, or
activate both the measurement of the material's electrical resistance and the measurement of
its mechanical characteristics.
The activation of items T ONLY and R+T is subordinated to the correct installation of the
linear position transducer on the machine.
The activation of items R ONLY and R+T is subordinated to the presence of the cables that
measure the electrodes' voltage on the spot welder otherwise said items may not be selected.
