ABSTRACT:
A spool gun having a quick connector connectable to an electrical power source and a gas source is disclosed. A connection line extends from the spool gun and is attached to a connector. The connector both fluidly connects the spool gun to a shielding gas source and electrically connects the spool gun to a power source constructed to generate a welding-type power. Such a spool gun is quickly and efficiently connectable to the gas and power systems required for performing welding processes.
