The Power Mode™ process was developed by Lincoln to maintain a stable and smooth arc at low procedure settings which are needed to weld thin metal without
•Short Arc MIG at low procedure settings.
•Aluminum MIG welding.
Power Mode™ is a method of high speed regulation of the output power whenever an arc is established. It provides a fast response to changes in the arc. The higher the Power Mode Setting, the longer the arc. If a welding procedure is not established, the best way to determine the Power Mode Setting is by experimenta- tion until the desired output result is established.
In the Power Mode two variables need to be set:
•Wire Feed Speed
•Power Mode Trim
Setting up a Power Mode procedure is similar to set- ting a CV MIG procedure. Select a shielding gas appropriate for a short arc process.
•For steel, use 75/25 Ar/CO2 shield gas.
•For Stainless, select a Helium blend
•For Aluminum, use 100% Ar.
Start by setting the wire feed speed based upon mate- rial thickness and appropriate travel speed. Then adjust the Volts/Trim knob as follows:
•For steel, listen for the traditional “frying egg” sound of a good
•For aluminum, simply adjust the Volts/Trim knob until the desired arc length is obtained.
Note the Volts/Trim display is simply a relative number and DOES NOT correspond to voltage.
Some procedure recommendations appear in Table B.4.
