Lincoln Electric IM849 manual Procedure Memory VS. User Memory, Memory Recalling, Memory Saving

B-12	OPERATION	B-12
	MEMORY PANEL DESCRIPTION

This panel performs these functions: limit setting and memory saving/restoring. There are six user memo- ries.

PROCEDURE MEMORY VS. USER MEMORY

Procedure memory is used while welding. Changes to the Power Feed 10A controls immediately change the contents of the selected procedure’s memory, such as Wire Feed Speed or Volts. Procedure memo- ry saving is done automatically. When the Power Feed 10A is powered up, the previous settings at power down will be restored.

Memory Panel user memories are used as storage and are not directly used while welding. When a user memory is recalled, the contents of the user memory are copied into the selected procedure where it can be used for welding. The user must explicitly save user memories on the Memory Panel.

MEMORY RECALLING

To recall a user memory, press and release the desired memory button. The memory is recalled when the button is released. When recalling a memo- ry, do not hold the memory button in for more than two seconds. A memory cannot be recalled while the out- put is enabled. The selected memory location (1-6) will illuminate the corresponding LED indicating that this memory location has been recalled. The LED will stay illuminated as long as no parameters are changed. Once any parameter is changed, the corre- sponding memory LED will turn off indicating that the stored values are no longer identical to the displayed values. However, this does not affect the stored val- ues in this particular memory location.

After holding the memory button in for two seconds the LED will turn off, indicating that the memory will be saved when the button is released. When saving a memory, do not hold the memory button in for more than five seconds.

Memory saving can be optionally disabled using Lockout Levels. If the user attempts to save a memo- ry when memory saving is locked, the Mode Select Panel will briefly display "Memory Save is DIS- ABLED!". Presently, Memory Panel Lockout Levels can only be accessed through a PC application or the IR Port.

MULTI PROCEDURE WELDING

The POWER FEED™ 10A CONTROLLER can do “On-The-Fly” welding with multiple weld procedures by using the Memory Panel. While welding, any Memory location can be accessed, and the parame- ters stored in that memory location will be switched to while actively welding. NOTE - This can only be done with Memory locations that have the same Weld Mode! While welding, any Memory location try- ing to be accessed with a different Weld Mode than the one currently being used will be ignored and an error message will be displayed. Up to six different weld procedures can be used while actively welding by using all six memory locations, as long as each location utilizes the same Weld Modes.

MEMORY SAVING

The Memory Panel enables the saving of all weld parameters and all user settable parameters, such as timers, Start Options, End Options, AC Controls, etc. To save a memory, press and hold the desired memo- ry button for two seconds. When the memory button is initially pressed, its indicator LED will illuminate.
