I am considering the 250P. Howerver, I have several questions.

1. It does not accept a spool gun. Which I am not a fan of anyway, but assuming it's a push gun that is supplied, are there any feeding issues when feeding softer alloys like 4043?

2. Is it possible to adapt a push pull gun?

3. I would be using the unit for aluminum mainly but would like to have the option for other metals. Is a liner kit available or would it be more practicle to purchase another gun?
