Frustration, disappointment, money blown off the scale

[speedyharry]

I wanted to learn welding at home so bought at auction an all singing and dancing hyper sophisticated TIG/stick welder. This is a brand new Lincoln Electric Aspect 375 amps K3945-1. It is an industrial type machine and I found that if I connected it up at home it would blow the whole street circuit. Easy answer - sell it, because I got it for a fraction of the catalogue price and I only wanted to recoup my losses so far. It now appears to me thus: The welder I bought was part A. It doesn't work without part B, which however is not available separately. Part B is sold only in combination with Part A, which I already have. Despite this, Lincoln Electric call it part number K3946-2, "Ready Pak". Naturally, it costs significantly more than K3945-1, which is already serious money. I could not sell Part A with a good conscience unless I point out in advance the vital absence of Part B (although Lincoln Electric are happy to omit this information).

The way to go therefore seems to be to purchase all or most of the items additionally included in the Ready Pak and offer them with the welder as one lot. If I bought these from Lincoln Electric their price would be prohibitive. I need help, therefore, as one completely clueless about welding, to know what tools and equipment will be needed to make welders of this high power work functionally to make fair the intended offer for sale. I am a complete beginner - be gentle! Thank you in advance
