By-pass condenser for Hi Freq add-on box?

admin

Manual on my Lincoln 500 amp HI-Freq calls for installing a by-pass condenser when used with a transformer welder.  The kit came with the box, I didn't acquire the welder.  Can an off the shelf condenser (or additional components) be sized to this 500 amp unit?  I didn't install this condenser the first time and something fried.  Was told by tech at that time you need to down rate the welder when running AC with Hi-freq,  he didn't mention anything about the lack of this by-pass condenser.Any ideas?Thanks,Alan
Reply:Something fried on the hi-freq unit or something fried on the welder? I would think if something fried on the hi-freq unit, it wasn't because of the missing condenser (capacitor), since the manual says the bypass condensor is to protect the welder. Can you supply more info on what fried?- John

Reply:I had to put one in my Weldmanpower G7.  Its just a cap across the outputs.  I bought it from Lincoln for a few bucks.  Never had any trouble tigging on AC with it at all.DavidReal world weldin.  When I grow up I want to be a tig weldor.
Reply:I am not clear on when or why this is required. I have a Ranger 9 and a Hi Freq Tig Module. I have added nothing to it and seems ok, but how do I know I don't need it?Lincoln Power Mig 210MP MIGLincoln Power Mig 350MP - MIG and Push-PullLincoln TIG 300-300Lincoln Hobby-Weld 110v  Thanks JLAMESCK TIG TORCH, gas diffuser, pyrex cupThermal Dynamics Cutmaster 101My brain
Reply:More than likely it is required to lower the output voltage of the torch output during the hi-freq stage if the torch isn't close enough to the work to conduct. For example, you accidentally stepped on the foot control with the torch in mid air."Common sense is not very common"http://www.tahoekeyshome.com

Reply:AC current is some how rectafied when you tig.  This is what can toast your welder.  I guess I missed what machine its being used on.DavidReal world weldin.  When I grow up I want to be a tig weldor.
