if you read my previous postings about my ESAB 161 unit, you'll know it's a awesome TIG unit, but has been back for repairs for a 2nd time.
it's been in shop (local welding shop that sells ESAB gear) for 2 months now. local ESAB rep was suppose to look at it for some time now. i emailed ESAB in SC and they responded to me immediately, wanting to replace the unit asap.
the new 161's have a high voltage filter on the AMP connector. my unit kept damaging itself because hv was arcing through the torch into the finger switch leads and back into the unit via AMP connector, damaging internal circuitry.
seems like ESAB corporate is very pro-active in helping customers, and the local reps seem to be too busy doing other things (trade shows)...
