JOG Mode

If the trigger on either gun is held for more than 3 seconds without striking an arc, the unit will automatically shut off weld power (and shielding gas output on MIG gun only), but will feed wire continuously at the preset wire feed speed (which may be faster or slower than Run−in Speed) until trigger is released.

Run−in Wire Feed Speed Settings

Run−in settings for the MIG and Spool Guns are independently set and stored in unit memory. The settings are in percent of the welding wire feed speed preset. Both settings are adjustable from 25 to 150 percent.

MIG Gun Run−in is factory set at 100%

which is recommended for most wire sizes and types.

Spool Gun Run−in is factory set at 50% which is recommended for .030 & .035 wire. A Run−in setting of 25% is recommended for .047 wire.

To check Run−in settings, start with the power switch OFF. Press and hold the MIG or Spool Gun Trigger while turning the power switch ON. The unit will power up with both the displays reading 888 , then the voltage display will read run and the wire feed display will read the preset Run−in percentage from memory for the gun selected. To return to the weld mode without making a change, simply release

trigger and pull the trigger again momentarily (one second).

To change Run−in settings, start with the power switch OFF. Press and hold the MIG or Spool Gun Trigger while turning the power switch ON. The unit will power up

with both the displays reading 888 , then the voltage display will read run and the wire feed display will read the preset Run− in percentage from memory for the gun se- lected. To change the Run−in value, re- lease the trigger and turn the wire feed con- trol knob (or the wire feed adjustment knob located on the bottom handle of the spool gun) to the desired setting for the selected gun. To return to weld mode after the Run− in speed change, pull the trigger momen- tarily (one second).
