This is a production duty Tweco Eliminator gun with 25 Foot lead and a EPG-CR2 Pre / Post purge gas controller. I believe this is a EPG225T-3545. It was acquired as surplus equipment. I have tested the controller for function and it works. The gun feeds smoothly. I do not know which configuration the gun is for power source - I.E. Lincoln or Miller, but it can be changed.

I checked with a supply house and both the gun and controller list for over $1000 EACH. This unit is available for $500, shipping included. No Warranty is included, as this is used equipment, but in very good condition. USPO MO only.
