I have had my everlast 520 unit for a while now and it is working fine (unlike my giant tech unit,,,,but I digress) This maybe a stupid question but seeing as how I have the giant tech ct520 not working right now I thought I would ask. On the tig torch it states to "clear the circuit". Yes I just now noticed it,,,lol...what exactly does that mean? I am assuming it means to hit the switch after it is turned off to drain the electrical components of stored energy. Is this correct because I just started doing that after having the unit for over a year or more. Or is that NOT what I should be doing and just let it disipate on its own like I have been doing?
