*1: This parameter is set as a percentage referred to the value of the following parameter: WELDING CURRENT
*2: The value of this parameter can be set as a percentage of the welding current or as an absolute value expressed in Amperes.
*3: SYN: This code indicates that parameters control is synergic. The optimal value of this parameter is set automatically by the microprocessor
on the basis of the preset welding current value. This value can be displayed but it is not user-adjustable.
*4: Available when "KIND OF PULSE" parameter= FAST
*5: Available when "KIND OF PULSE" parameter= SLOW
