high-freq TIG near a TV?

admin

I'm working in a tiny shop and things aren't as spaced out as I'd prefer.  I have a desktop PC in there connected to a flat screen LED TV (via an HDMI connection) that I use for CAD and running MACH for a CNC machine.  Anyway, quite often when welding, the connection between the TV monitor and PC is lost.  It's a sporadic in and out and seems to happen mostly with a high frequency TIG start-up.  Until I move to a larger shop, I'm stuck with my existing layout.  Can anyone shed some light on exactly why this problem is happening?  And is there any type of product to act as a buffer for this issue?  Some kind of inline filter or something?"There are two types of people in America - those who try to classify everyone into two types and those who don't."

Reply:Your Dynasty has a section addressing the HF interference which does mention Ground/bonding all metal in a shop but the Welder Tech dude mentions the wrapping of the work lead and torch cables as a pretty effective and simple method to stop the interference.They shut down the Miller Forum so I can't search the other posts he mentions this in.Ed Conleyhttp://www.screamingbroccoli.com/MM252MM211 (Sold)Passport Plus & Spool gunLincoln SP135 Plus- (Gone to a good home)Klutch 120v Plasma cutterSO 2020 benderBeer in the fridge
Reply:"09-11-2013, 02:37 PMBeing an older transformer machine, simply twist tye the tig torch cable to the work lead, first 2' after leaving the machine. Presto zero interferance.The ground rod idea, is silly unles you know exacty the moisture content in it. Few do."https://forum.millerwelds.com/forum/...y-interferenceEd Conleyhttp://www.screamingbroccoli.com/MM252MM211 (Sold)Passport Plus & Spool gunLincoln SP135 Plus- (Gone to a good home)Klutch 120v Plasma cutterSO 2020 benderBeer in the fridge
Reply:I'll trying wrapping them 2' out and see where that and the RFI suppressors on the TV cable gets me.  Thanks!"There are two types of people in America - those who try to classify everyone into two types and those who don't."

Reply:Follow up:  Nothing I did to suppress this made a difference.  I ultimately ended up moving this TV to a bedroom and bought a Vizio for the shop.  It seems to only be affected about 2% as often as the Insignia.  So brand/quality of TV does matter."There are two types of people in America - those who try to classify everyone into two types and those who don't."
