I would possibly look into staying away from sip welders. I am led to believe that they have bit of an industry reputation for being rubbish. I'm only basing this on their mig welders though and I think the main complaint is the wire feed. Obviously not a problem on a tig unit.
We had a sip 130 mig and it was pretty rubbish. sold it and got given a free oxford one which is far better even though its about 20 years older.
