can we upgrade LINCOLN R3R 500 welding machine to High frequency TIG machine?
with the help of an attachment(TIG module) same as that of LINCOLN?
Because our contract specification demands HF machines for TIG welding(scratch start is not permitted),
Currently we have only R3R 500/ 600, CV-655 models(LINCOLN) only..So i
just want to know that is it possible to upgrade/convert these machines
to HF(high frequency).,with the aid of any attachments/alteration.,
