Q. Does this unit come with a foot pedal, or can I purchase one separately?
A. No, the TransSteel 3500 (TIG/STICK Version) supports lift-arc TIG, and Fronius does not offer a foot pedal for it. 

Q. Does the MIG package come with a stick electrode holder?
A. No. You can either purchase the stick electrode holder and assembly separately, or you can upgrade to the multi-process package that includes everything required for MIG, TIG and STICK welding.
