Lincoln Electric IM584-D Control BOX Panels -- SET UP Controls Description, K1542-12 MSP2 Panel

B-4 OPERATION B-4

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 toggle switch. Moving the switch bat up or down adjusts the displayed value in the correspond- ing direction. Holding the switch in either direction will cause the display to move quickly in the correspond- ing 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 ʻOnʼ 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.

K1542-12 MSP2 Panel:

This panel provides a selection of over 25 weld modes, including CV, pulse, FCAW and CC, through a toggle switch and indicator lights (LEDs). It allows for adjustment of all set up parameters, Preflow, Run In, Arc Control, Burnback, Postflow, and Crater, through an up/down toggle switch, indicator lights and a 3 digit display.

To adjust a set up parameter (Weld Mode being one of those parameters), first select one of the set up parameters for adjustment, and then adjust the dis- played 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 an 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 is shown on the MSP2 panel digital display. The value can be modi- fied with the Set switch. The Set switch is an up/down center-off momentary toggle switch. Moving the switch bat up or down adjusts the displayed value in the cor- responding direction. Holding the switch in either direc- tion will cause the display to move quickly in the corre- sponding 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 ʻOnʼ 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.

CONTROL BOX PANELS -- SET UP CONTROLS DESCRIPTION

Certain large option panels can modify the set up parameters Preflow, Run In, Arc Control, Burnback, Postflow, and Crater. The meaning of those parame- ters, and their maximum and minimum values, follows.

Preflow - Time delay after the trigger is pulled, but before weld starts, during which shielding gas flows. Weld start is defined as the time when both the power source is energized and the Wire Drive begins feeding wire. Adjustable from 0.0 (Off) to 2.5 seconds in 0.1s increments.

Run In - Wire feed speed during arc starting. Wire Drive will feed wire at the Run In speed for one sec- ond, or until weld current flows. Low speed gear range: Off (Run In speed equals weld wire feed speed) or adjustable from 50 to 150 IPM (1.25 to 3.80 MPM). High speed gear range: Off (Run In speed equals weld wire feed speed) or adjustable from 75 to 150 IPM (2.00 to 3.80 MPM). NOTE: Run In settings over 150 IPM produce strange display values used for troubleshooting and service. If encountered, reset Run In to 150 IPM or less.

Arc Control - Unitless characteristic, also known as Inductance or Wave Control. Allows operator to vary the arc characteristics from “soft” to “harsh” in all weld modes. Adjustable from -10.0 to 10.0 in increments of 0.1. Off (0.0) is nominal.

Burnback - Time delay after the trigger is released during which the power source remains energized but the Wire Drive stops feeding wire. Adjustable from 0.00 (Off) to 0.25 seconds in 0.01 second increments.

Postflow - Time delay after burnback is complete, during which shielding gas flows. Adjustable from 0.0 (Off) to 10.0 seconds in 0.1 second increments.
