B-2 OPERATION B-2

The user adjusts WFS according to factors such as weld size, penetration requirements, heat input, etc. The power source then uses the WFS setting to adjust its output char- acteristics (output voltage, output current) according to pre- programmed settings contained in the power source. In constant current modes (arc gouging, stick, TIG) this control adjusts the output current, in amps. An LED lights to inform the user which function (WFS or amps) is active.This display can be either English or metric units. Further, this display can be set up to display either WFS or amps when using wire welding modes. (See SETTING DIP SWITCHES in the INSTALLATION section.)

The right knob is labeled VOLTS / TRIM. In constant volt- age modes (synergic CV, standard CV) the control adjusts the welding voltage. In pulse synergic welding modes (pulse GMAW only) the user can change the Trim setting to adjust the arc length. It is adjustable from 0.50 to 1.50. A Trim setting of 1.00 means than no adjustments will be made to the preset arc lengths, and is optimum for most conditions. An LED lights to inform the user which function (volts or trim) is active.

Both displays indicate preset values, according to the weld mode selected, when not welding. Once welding begins, they switch to displaying actual values. At that time, the indicator LEDs will flash to signify actual values are being displayed. The displays hold the actual values for 5 sec- onds after a weld is stopped. Turning a knob during the hold time shuts off the hold, and returns the meters to their preset values.

The allowable settings are determined by other system com- ponents. The WFS range, for instance, is dependent upon the gear range in the Wire Drive and on the welding pro- grams in the Power Wave power source. The voltage and current are similarly limited by programs in the Power Wave.

Control Box Panels - Lower Panels

A description of the set up controls, Preflow, Run In, Arc Control, Postflow, and Crater, and their maximum and mini- mum values, is in Control Box Panels - Set Up Controls Description in this section.

K1542-4 CV/Gouge Panel:(Std.)

The CV/G Panel has a single toggle switch for selecting between two weld modes: CV welding and arc gouging. All other set up parameters, Preflow, Arc Control, Postflow, and Crater, default to zero or off. Run-in defaults to the mini- mum value, or to the weld speed depending on the position of its associated dip switch. (See “Setting DIP Switches in the Control Box” section.) Burn back defaults to the on- board trimmer adjustment. When used with the Dual Procedure or Memory options, only the WFS/Amps and Volts/Trim settings are saved.

Selecting the Gouge mode immediately energizes the output terminals on the power source. The output cur- rent is set by the Amps control. The Volts/Trim adjust- ment has no effect in this mode.

K1542-11 MX2 Panel:(Optional)

This panel provides a selection of four weld modes: CV/MIG, CV/Flux Cored, CC/Stick/soft and CC/Stick/Crisp through a toggle switch and indicator lights (LEDs). It allows for adjustment of all set up para- meters, Preflow, Run In, Arc Control, Burnback, Postflow, and Crater, through an up/down toggle switch, indicator lights and a 3 digit display.

Weld modes are selected with the Mode Select switch, an up/down center-off momentary toggle switch. Moving the switch bat up or down moves the Weld Mode LED in the corresponding direction. Holding the switch in either direction will cause the indicator to move quickly in the corresponding direction until the switch is released, or the upper or lower limit is reached.

To adjust Set Up parameters, first select the Set Up parameter for adjustment, and then adjust the displayed value up or down.

Set Up parameters are selected with the Select switch, an up/down center-off momentary toggle switch. Moving the switch bat up or down moves the Weld Mode LED in the corresponding direction. Holding the switch in either direction will cause the indicator to move quickly in the corresponding direction until the switch is released, or the upper or lower limit is reached.

The value of the active Set Up parameter, as defined by the Set Up LED, is displayed on the MX2 panel Set Up display. The value can be modified with the Set switch. The Set switch is an up/down center-off momentary tog- gle switch. Moving the switch bat up or down adjusts the displayed value in the corresponding direction. Holding the switch in either direction will cause the display to move quickly in the corresponding direction until the switch is released, or the upper or lower parameter limit is reached.

To energize the output studs in either CC/Stick mode, the right Control/Display panel knob, labeled Volts/Trim, must be used. The Volts/Trim knob must be turned clockwise roughly a quarter revolution to energize the output studs. (The Volts/trim display will indicate ‘On’ when the studs are energized.) Similarly, turning the knob a quarter turn counter-clockwise de-energizes the output studs. If a CC/Stick weld mode is entered through use of the Dual Procedure, the studs will be in the same state as when they were last used. If a CC/Stick weld mode is entered through a Memory recall, the studs will be de-energized.
