You can try to buy a converter for 110 to 220v
About that... If you mean getting a step-up transformer -- beware of ANY sold as 'International voltage converters" such as sold by
http://www.world-import.com/transformers.htmIn short, they are woefully over-rated for power. I had 2 of their 2,000w transformers with early s9's (1,450-1500w) on them. Ran very warm which is normal for xmfr's but after 3 months both transformers had failed. I opened them up to find charred windings. Now we know why they are so cheap...
Replaced them with REAL transformers from AutomationDirect for around $189 each (vs $54) and as expected, being industrial units they should last forever.
