Crater - Used only when welding with the 4-Step trig- ger mode. Can be set to Off or On. When On, Adjustments can be made to WFS and Volts/Trim on the Control/Display panel. These settings are then used for ʻcrateringʼ when in the 4-Step trigger mode (see explanation of 2 Step and 4 Step operation below). When Off, ʻcrateringʼ is not possible.

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 S1-1, S2-6 and S2-7. (See “Setting DIP Switches in the Control Box” section.) Do not allow the panel to hang by the wiring harness.

Determine if the Wire Drive is set up for low or high speed. If low speed, S1-1 should be off. If high speed, set S1-1 to on.

To adjust the lower limit, set S2-6 to on. Turn the power on and adjust the WFS/Amps and Volts/Trim knobs to the desired lower limits. Note: You will not be able to adjust the lower limit outside of the minimum and maximum wire feed speed of the Wire Drive, nor above the upper limit. Turn the system power off. Return S2-6 to off.

To adjust the upper limit, set S2-7 to on. Turn the power on and adjust the WFS/Amps and Volts/Trim knobs to the desired upper limits. Note: You will not be able to adjust the upper limit outside of the mini- mum and maximum wire feed speed of the Wire Drive, nor below the lower limit. Turn the system power off. Return S2-7 to off.

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 non-syner- gic CV modes. Procedure B could be set up with dif- ferent limits. Limits are absolute -- they will override values stored in the memories. Note that limits do not apply to set up parameters, such a Preflow and Arc Control.
