Dear Ishikawa san
Sorry for my mail
I got some question from Michelin as below 
Could you give me some suggestion before inform back to customer ?
Hello Mr.Ruangsak 
 I am Feng shen, from Michelin China ,now I am the customer of Miyachi welding device IS-120B. 
1.now Miyachi China provide Michelin China IS-120B and Miyachi Thailand provide Michelin Thailand ISB-330A 
 now we already used IS -120B for several month in Michelin China and the performance of IS-120B already been validated by Michelin for our product quality. 
 so could you please give me the reason why you advice us to buy this new type of welding device in Thailand? 
 2. if we use this new version, we need an official document to point out the difference between 2 types welding device(current, welding quality, performance and so on ,the more clearly ,the better) 
 and make sure the new type(ISB-330A) is better than the old type(IS-120B). if not ,we have no reason to use a new type of device instead of a device which already validated. 
 do you have this kind of technical description document ? 
 (you should have this kind of document ,because of welding quality is quite important for the customer ,all the customers need this kind of document to make sure the update new version have no risk) 
3. in the future, we will order welding device all over world in Michelin plant including Asia, Europe and America(Brazil and US ),We could not have a different version/type in each country. 
 do both (IS-120B) and (ISB-330A) have the CE certificate ? 
 could you tell which is easier to buy all over the world? 
 when you won't provide old version(IS-120B) of the machine ? 
 are the price the same? or the gap of price will become bigger? 
maybe some of the question are linked to the all the world market, if you have no clearly answer ,could you help to forward this mail to the Miyachi Japan. 
or share with me the contact list in Miyachi Japan .I can contact with them about these several topic
