NO. NO. NO. You can't, and we shouldn't have. That was our mistake based off of faulty factory supplied info. Disregard that for the future if you were told that. The old economy torches were built a little differently and the factory said they could be used, (but I never heard up to 200 amps that I can recall). They'd hold up for a little while but would evenutally and inevitably break down. But Your torch is toast if that is what you've been doing for very long.
Rambozo was referring to CK. They target professionals, and have until the last two or three years when social media came into its own. They do have an app that tells you which common Everlast units fit their most common torches and what you need. Just released in 2012. But they refuse to do certain machines as they do not "want" to pursuit that type customer.
