Hey guys it's my first time on here. I would like to know what equipment is needed to tig weld with my new bobcat welder. I've been told that I can't weld aluminum with it so would I be better off with a mig attachment or suitcase extreme? Thanks for any info you can give me.

Who said you can't TIG aluminum with the Bobcat?
By itself for AC no, but just add an HF-251D-1 high frequency arc starter and have at it. You won't have remote amperage control with a Bobcat which can limit your aluminum TIG options. The TIG torch will be hot all the time unless the HF-251D has the optional contactor and you use a foot or finger control to activate it.
If you want to hook it up you can use the HF-251D-1 on DC too for HF start instead of scratch but you still won't have remote amperage control or contactor.MM200 w/spot controller and Spoolmatic 1

My local air gas where I purchased my Bobcat told me that it was probably not a good idea to tig with it. But the Nex air down the road gave me the same info you have. Before I worked on the Railroad I worked in machine shops and tig welded, but have never tig welded in the field. I was pretty sure you could just didn't know what equipment would make it possible. Thanks for the info.

They may have meant "it was probably not a good idea" from the standpoint of what was pointed out above with regard to no remote amperage control, no contactor and no high frequency when used for TIG by itself. I would have asked them to be a little more specific in their claim.
But the manual itself confirms TIG is a process the Bobcat is capable of only it states "Non-Critical TIG" as cruizer mentioned earlier.MM200 w/spot controller and Spoolmatic 1

That machine will DC tig ferrous metals with excelent results. No need for fancy hf start and remote amp control with DC tig.Lincoln Idealarc 250
