Profax AEC-200 upgrade spool gun, with 50' leads.  Direct connection (no adapters needed) to replace the original Linde/ L-Tec/ Esab obsoleted ST-23A spool gun.  Whatever power supply, welding machine, or adapter box you had your ST-23A attached to, this gun will work.
Spool gun is rated at 250 amps in argon 60% DC.  Uses standard 4" wire spools. Will feed wire 0.025" through 1/16". With standard nozzle. For higher heat, larger diameter wire we offer heavy-duty straight, 45' bent, and a flexiable 12"  barrel. 
 
Normal UPS ground, in the lower 48 states, paid if ordered on the website.
