Close valve on cylinder when finished welding. 3 Spool Gun/MIG Gun Switch Switch must be set in Spool Gun position for spool gun to operate. 4 Trigger Press trigger to energize welding power source contactor, start shielding gas flow, and begin wire feed. 5 Wire Feed Speed Control Wire feed speed is controlled by welding power source Wire Speed control (see welding power source Owner’s Manual or door chart for appropriate setting). 6 Voltage Control Arc voltage is controlled by welding power source Voltage control (see welding power source Owner’s Manual or door chart for appropriate setting). To purge shielding gas line, set gun selection switch (item 3) to the MIG Gun position.Press spool gun trigger to energize gas valve. Shielding gas will flow, but spool gun will not feed wire. Hold trigger in for several seconds to purge gas line. Return gun selection switch to the Spool Gun position before welding. 1 2 Spool Gun 3 MIG Gun 4 6 5 CCC CCC CCC OM-230 261 Page 15 SECTION 5 .
