Voltage Trim	Relationship to Preset Voltage
0.6	60% of preset voltage
0.8	80% of preset voltage
1.0	no change to preset voltage
1.2	120% of preset voltage
1.4	140% of preset voltage

If, for example, the minimum voltage trim is set to 0.8 and the maximum voltage trim is set to 1.4, this means that the voltage for a given wire feed speed can be adjusted to be anywhere between 80% and 140% of the preset voltage of that wire feed speed.
