Hello everyone,
I'm new at this welding in fact my welder (140E) is still in shipment LOL. I do have a question, about welding "Aluminum" and its this, Oh I will be getting a spool gun a little later but, for now I will be using the gun that comes with the machine and I'm wondering If I have a new welder and gun and start out welding only aluminum do need a "Teflon liner" or I can just use the one that is the gun since I'm only welding Aluminum from the start? If I do need to replace the liner is this something a newbie can do or a task for the dealer. Hope to hear from you soon.

Thanks
