6. CV/GOUGE PANEL

The CV/Gouge Panel provides a fixed toggle switch selection of two power source modes. The upper position selects the generic CV/MIG mode from the power source while the lower position selects the GOUGE mode.

OPTIONAL PANELS

A number of Optional Features are available for use with the Power Feed 10. Some Installation informa- tion is provided in the ACCESSORIES section,

REFER TO THE INSTRUCTIONS THAT COME WITH EACH KIT FOR DETAILED INFORMATION REGARDING INSTALLATION.

BOARD LEVEL ADJUSTMENTS

The control box motherboard provides the capability to adjust some basic parameters as follows.

BURNBACK

The BURNBACK trimmer (R5) is provided as a basic adjustment for burnback time. The range is 0.0 to

0.25seconds, CCW limit is minimum, CW limit is maximum. This value is overridden by any option with the ability to independently adjust burnback.

preprogrammed voltages; for example, to compen- sate for cable and fixture voltage drops. The preset voltages can be adjusted on the wire feeder’s voltage display. When a change is made to the voltage at one wire feed speed, this change is applied to all other wire feed speed settings. For example, if the operator turns up the voltage by 10 percent, the machine automatically increases the preset voltages at all the other wire feed speeds by 10 percent. The preset voltage, programmed at the factory, may be changed with the wire feeder VOLTS adjustment.

ARC GOUGING

Arc gouging can be performed by choosing the arc gouging weld mode. Doing so automatically ener- gizes the output terminals on the Power Wave, mak- ing the power source immediately ready to gouge. The output current is set by the AMPS control on the Power Weld wire feeder. The VOLTS/TRIM adjust- ment has no effect in this mode.

The ARC CONTROL adjusts the arc force. Increasing the ARC CONTROL setting increases the arc force, making the arc more harsh but less likely to stick. Decreasing the ARC CONTROL setting decreases the arc force, making the arc softer and smoother.

WELD MODE DESCRIPTIONS

CONSTANT VOLTAGE (CV/MIG)

For each wire feed speed, a corresponding voltage is preprogrammed into the machine through special softwares at the factory. This preprogrammed volt- age is the best average voltage for the procedure at the given wire feed speed. If the wire feed speed is changed on the wire feeder, the voltage automatical- ly changes with it.

ELECTRODE ROUTING

The electrode supply may be either from reels, Readi-Reels, spools, or bulk packaged drums or reels. Observe the following precautions:

a.The electrode must be routed to the wire drive unit so that the bends in the wire are at a minimum, and also that the force required to pull the wire from the reel into the wire drive unit is kept at a minimum.

b.The electrode is “hot” when the gun trigger is pressed and must be insulated from the boom and structure.

c.If more than one wire feed unit shares the same boom and are not sharing the some power source output stud, their wire and reels must be insulated from each other as well as insulated from their mounting struc- ture.
