200dx loosing arc during weld on ac

[jeffcw30]

Just got my 200dx and I started running beads . after about 10 min I would loose arc during weld. I would back off pedal. And nothing. Then it would run a few beads fine. First 45 min of use it happened about 4 times. I have read about people have ing to adjust. There points because of high frequency issue but can u loose an arc after weld bead has started?? Or do I have somting else going on ?? Thanks for your help

Is the duty cycle light coming on? Maybe you are exceeding the duty cycle of the machine. What kind of welding are you doing at how many amps?

Rambozo no lights on and I never went over 140 amp and most of the time was between 90 and 120. Just a side note the digital amp display would drop down to 35 when welding. It would only go up to 120 or what ever I had it set at after I stopped the weld. This may be normal for the machine, I'm not sure.

It's normal for the unit to change the reading on the unit to read actual amp output. If it is showing only 35 with the pedal opened up, then there's an issue with the pedal likely.

This is supposed to be the updated pedal? I thought at times it took along time to puddle. I plan to run a lot more beads today. I want to make sure its not me. But I'm sure its not. I'm not a pro by any means but I did have a miller syncrowave , I just wanted an inverter because 90% of what I do is aluminum. Mark are the updated pedals still having problems? Thanks, I've had a lot of bumps in the road with my order until now but fit and finish is good. And when I get these bugs worked out I think I will be pleased.

Well, IF you have the new style, they still they are not perfect. The potentiometers can give issues from time to time though issues are a lot lower. We have the SSC pedal...which is still as good as you can get anywhere. Some people tend to over sell the new pedal...it's an improvement but not where the SSC is. It's much better, but not up to speed with the welder and its quality.

I guess I'm not following u , do mean this SSC pedal is a different pedal than the "upgraded" pedal that I got . if so do u sell the SSC and how much?

Absolutely. It isn't the SSC unless you paid abou 159.00 for it plus 15.00 shipping extra. There's still a big difference and you can't mistake the two. The SSC has a sanded top surface. It is wider and flatter than the current pedal.

Well I spent some time running more beads and it is still loooosing arc intermittently . so I guess my question remains is it the pedal and how to be sure?

[jeffcw30]

So I went out again today and ran some more beads, this time with the torch switch. I am still Loosing my arc ( very sparatic ) tends to happen more after I use for a little bit . it would happen when I tried to start the puudle, and the arc would just go out. With the switch still engaged I could scratch start but sometimes it would go back out a couple seconds later. After that it would run a few beeds with no trouble. Good ground ,clean metal, good arc length. All other functions seem to work fine and make adjustments. This gets me back to my original post "could this be a high frequency problem". When this is not happening it works great. Never exceeded 140 amps no lights on

No it's not a HF problem. HF has nothing to do with AC welding in an inverter other than starting the arc.

Mark thanks for your time. If its not a high frequency problem I'm OK with that, but I tried it with the foot pedal and torch switch and it still happens. I used it for an hour or so every day. I will admit I don't know how the electronics work inside the welder so what could it be? I definitely have a problem just need to know where to go from here? If I can get this fixed life will be good, thanks again

mark where did you go???

Your best bet might be to call Ray in the repair dept., to see if there are any other field checks you can make or if the machine needs to be sent in for repair. Sometimes it's nothing more than a connector that came loose in transit.

I thought the same thing with my 250EX but it was a circuit board problem. It would weld OK and then it would start to weaken as the arc would sputter and if I went past a certain point with the pedal, it would almost come to a stop.

I ended up getting a 1450 error code and so I had to send it in still under warranty. (Thank goodness for the 5 year warranty!) It was an amperage problem and so I still do not have it back after almost 5 weeks. I know they are going through a moving situation with Everlast's tech station so I cut them some slack with the fix.

I do miss my 250EX tig welder though. When it was working, it was a joy to use. I can't wait to get it back.

Just an update, worked with ray at tech support and made all suggested changes and still had arc problem only on ac. Long story Short everlast sent me out a new machine same day ray and myself could not come up with a solution. I upgraded the machine to a 250 ex . alex made no hesitation in helping me and ray communicated with me very well., what else could you ask for! The 250 ex showed up today and I went out and did some testing, about a half hour. So far no arc problem. I get my SSC pedal tommarow and plan to do a lot more testing on sat. I will be sure to post results. So far so good.
Just a note I work in the auto repair industry and have for 17 years. I understand there are problems with parts, machines, shipping, and things out of our control. But I how a company handles it, what counts. So far alex, Oleg, and ray have been great. And if I have a problem again that why I have a warranty. " all machines are built by humans" thanks again.

Thanks for the update. That kind of service means a lot.
