    high-freq TIG near a TV?

    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?

    Any tips on Grounding the machine? I'm running a Miller Dynasty and I can't think of how to set up a proper ground for it in my drywalled shop.

    Meanwhile, I'll order up some RFI suppression rings on Amazon and see how those do. Thanks for the link.

    The guy from the old Miller forum is a Welder tech.

    He is saying wrap the work lead (ground) and torch lead together 2-3'.

    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.

    Being 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."

    I'll trying wrapping them 2' out and see where that and the RFI suppressors on the TV cable gets me. Thanks!

    I have an old transistor radio in my shop that has come on several times when I start an arc with my HF tig.

    I almost forgot that I can sometimes activate my welding positioner with my welder too. Will just randomly come one across the table.

    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.
