CONTROL BOX -- PC BOARD ADJUSTMENTS
The Control Box Mother board provides the capability to adjust some wire feeding parameters as follows:
Acceleration: The motor acceleration can be varied in five steps, from slow to fast. See “Setting DIP Switches in the Control Box” section.
Burnback: For the options which cannot adjust the Burnback set up parameter (CV/G and M panels) a PC board adjustment (trimmer R5) is provided. The range is 0.0 to 0.25 seconds, increasing in the clock- wise direction. This is ignored by options which have the ability to adjust Burnback (MX2 and MSP2 pan- els).
Run In: For the options which cannot adjust the Run In set up parameter (CV/G and M panels) a PC board DIP switch setting is provided. In one position, the run in speed will be the minimum Wire Drive WFS. At the other setting, run in will occur at the same speed as set on the WFS knob. This DIP switch setting is ignored by options which have the ability to adjust Run In (MX2 and MSP2 panels). See “Setting DIP Switches in the Control Box” section.
With system power on, select the weld mode for which you want to set limits. If a Dual Procedure option is installed, select the procedure A. Turn the system power off. Remove the two screws holding the Control/Display panel to the Control Box, but do not unplug it. Tilt the panel down to allow access to DIP switches
Determine if the Wire Drive is set up for low or high speed. If low speed,
To adjust the lower limit, set
To adjust the upper limit, set
If a Dual Procedure panel is installed, repeat the above procedure with the Procedure B selected. When done, attach the Control/Display panel to the Control Box. The machine is now ready for normal operation with the new limits.
CONTROL BOX -- SETTING OPERATING LIMITS
Upper and lower operating limits can be set for the WFS/Amps setting and the Volts/Trim setting. Doing so requires knowledge of how to set the limits, and access to the PC board in the Control Box.
There are two independent sets of limits, Procedure A limits and Procedure B limits. If a DP/M door option is installed, the A and B limits must be set independent- ly. If there is no DP/M door option, the Control Box defaults to Procedure A, and only Procedure A limits can be set.
CONTROL BOX -- USING OPERATING LIMITS
Once set, limits apply to all weld modes. Limiting Procedure A to 200 to 300 inches per minute, for example, limits the ability of the operator to adjust his WFS in pulse, CV and FCAW weld modes. Limiting the Volts to 23.0 to 24.5 would limit the ability of the operator to adjust his Volts in synergic and
