adding pulse feature to existing welder

[todd8541]

How difficult is it to add a pulse feature to an existing welder. I have a econo tig 165 and would like to add pulse to it. I don't have the serial number with me as i am at work but I can post it later if needed.

Thank you
Todd

Never had that option, sooo, simply not happening, even if it did, that unit is obsolete.....
