OPERATION

TABLE B.3 – RELATIONSHIP BETWEEN VOLTAGE TRIM AND PRESET VOLTAGE

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

Explanation of Table B.3:

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.

TABLE B.6 – RELATIONSHIP BETWEEN

SELECTED ARC LENGTH TRIM AND PRESET ARC LENGTH AS INDICATED BY ARC LENGTH TRIM, GMAW FCAW ONLY

Arc Length Trim	Preset Arc Lenth
0.6	60% of preset length
0.8	80% of preset length
1.0	no change to preset length
1.2	120% of preset length
1.4	140% of preset length
