- Consequences of a lower value:
• More reliable starting.
• ARC SET
○ In pulsed synergic welding this parameter directly influences the size of the welding pulses.
○ The value SYN=100 denotes the optimal synergic value chosen by the manufacturer.
- IMPORTANT NOTE: This parameter should be adjusted as little as possible. To correct synergy
it is advisable to use arc correction by means of the voltage parameter. This parameter can be
useful if the material or gas used is different from that of the synergic curve.
○ If you set a value other than SYN, this value is stored and fixed.
- Consequences of a higher value:
• Hotter welding.
- Consequences of a lower value:
• Cooler welding.
• PRE GAS
○ Time of gas delivery before the arc strike.
- CAUTION: an excessively long value will slow the welding procedure. Other than in the presence
of special requirements the value should generally be kept at 0.0 s or anyway very low.
- Consequences of a higher value:
• This parameter allows a shielded environment to be created, thereby eliminating contaminants
at the start of the welding pass.
• SOFT START (MIG/MAG manual welding mode)
○ The SOFT START is the wire approach speed to the workpiece.
○ The value is expressed as a percentage of the set feed rate.
- Consequences of a lower value:
• The start of welding is "softer".
- Consequences of a higher value:
• The welding start may prove difficult.
• SOFT START

.
○ The value is expressed as a percentage of the set feed rate.
○ In synergic welding the optimal SOFT START value (indicated with SYN) varies in general with
variations of the synergic parameters.
○ In synergic welding, if the value SOFT START = SYN is selected the welding power source will
always have the optimal SOFT START value set when the main welding parameter changes.
○ If you set a value other than SYN, this value is stored and fixed.
- Consequences of a lower value:
• The start of welding is "softer".
- Consequences of a higher value:
• The welding start may prove difficult.
• BURN BACK (MIG/MAG manual welding mode)
○ The BURN BACK value is associated with the quantity of wire that is burnt at the end of the weld -
ing procedure.
- Consequences of a higher value:
• Wire significantly retracted into the torch nozzle.
- Consequences of a lower value:
• Stick-out at welding start is longer.
