Pressing the Jog/Purge switch allows the operator to jog wire without energizing the weld power or gas valve circuit.

•The unit provides the ability to jog the wire feeder by means of the gun trigger or the Jog/Purge switch. If the welding arc does not initiate in 3 seconds after the gun trigger is activated, the unit will perform a jog operation for a maximum of 30 seconds. If the gun trigger is still activated after 30 seconds, the jog operation is terminated to prevent complete unspooling of the wire, in the case of a damaged gun. The unit

displays the “ERR STRT“ message to inform the operator that the trigger is activated.

•Jog speed can be adjusted by the Adjust control when the unit is jogging wire. The unit displays jog speed when the unit is being jogged.

•Jogging can also be accomplished by pressing the Jog/Purge button.

•Pressing the Jog/Purge button also allows the operator to purge gas lines before

welding and to preset gas pressure at the regulator.

•This unit is equipped with Auto Thread capability. By rocking the switch from purge to jog within 0.5 seconds will automatically feed wire for a factory default setting of 192 in (4877 mm) of wire before stopping. The default feed rate is 700 ipm. These settings can be changed using an optional PDA with File Management software. Pressing the Jog/Purge switch or gun trigger during Auto Threading will terminate the automatic feed operation.
