To recall a memory setting, simply push that memory button. That memory’s contents will be immediately recalled to the Control box.
If the ‘Memory Change with Trigger Pull’ DIP switch is on (see “Setting DIP Switches in the Control Box” sec- tion) it is possible to recall a given memory by quickly pulling and releasing the gun trigger before welding. To switch to memory ‘n’, simply pull and release the gun trigger ‘n’ times without attempting to weld. The trigger pulls and releases must be done quickly, in rapid succession. If too much time is allowed to pass, the memory location will not change. Note that when- ever the trigger is pulled, a welding sequence (pre- flow, run in, etc.) begins, so the electrode should not be allowed to contact the work piece.
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)
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
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.
Crater - Used only when welding with the
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.
