  • 180sd problem

    I have a 180 sd, in tig when I press the remote pedal it makes the arc like if it is at 180 amps, even if the amp is set to 80 amps. Can somebody help.

    thanks

    I would pull the cover and check for a loose connection. Does the panel amp control work in stick mode or lift arc without the remote? Make sure the machine is clean inside and nothing is shorting out. IE Grinding dust.

      Check the cord going to the foot control, make sure nothing's damaged (hunk of metal dropped on it) shorting some wires. If it's OK see if everything is clean & looks OK inside the foot control...Sounds like something in the circuit is telling the welder the foot control is wide open...
      All this is assuming the welder is out of warranty! If it's still in warranty...CALL MILLER FIRST!!!!!

        Mine did that last October

        "I finally took it in . The transducer (HD-1) was bad. Cost me 60+120 labor. Guy said he only worked on 2 of these 180's before. That's good news.
        Bad news is when I started to weld, I found that I now had a scratch start tig! I was not a happy boy. Pulled the side cover off and saw a black wire dangling from the hv xformer to the resistor above. Plugged in the piggyback connector, and I'm good to go."

            uh....Miller?

            You might call your local Miller rep and order through them. If still under warranty you could call Miller support first. They sent me a part before when mine was under warranty. They gave me the option to install it myself or take it in to a service center. I had the part in my hands in two days. Excellent service.
