who owns a Syncro 200? hey tech guys...

[SignWave]

I think i did this once before. Im still having trouble with my machine. Since im still very wet behind my ears when it comes to tiggin' Im not sure if what im seeing is whats supposed to be happening or not.

If im doing 0.125" AL 6061 or 5086, I'll generally set my amps to around 95-110. This seems to work "okay". My beads come out looking fairly decent and the cleaning action leaves an etch zone that is about 1/4 the width of the bead. balance is around 1.0-1.5

My problem lays in the fact that I think this machine isnt working right... It doesnt seem to matter where I set the balance, the cleaning action does not seem to change.

also the arc strike counter resets at 100 cycles. so my machine has like 20 hours of weld time but only 10 cycles... those are some REALLY long weld beads...

If i go half pedal (max 90A) say 45 amps, on 1/16th Al, the machine doesnt seem to produce a good bead or any cleaning action whatsoever and the arc is very unstable.

So am I doing something wrong or is ther a good posibility that its pooched?

Anyone out there with some insight, your opinions are greatly appreciated.

Regards, Rich

We have a Syncro 200 & 250, problem is:, that I would have to improve just to suck at tig. However, my guys use them on a daily basis and the issues you have described have never (at least as far as I know) happened. I'll copy your thread and give it to one of the guys and see if they can shed some light on this. It sounds like something is out of wack though. Get back to you soon..

do you have a pic so we can help you out.

Rich, try to wait a day. If you don't get more responses, try to re-post on the discussions side. Try it about 10am your time....

I am using a 3/32 2% ceriated or thoriated. it doesnt matter the results are the same. Its not about the electrode. its about machine. I may be wrong and I should go recheck, but I dont think that there is any control over frequency other than the set the hot start/cold start values. I have a choice of hot medium or cold. It stays on medium for the most part unless im doing some thick plate.

The arc dances around if im at half pedal. I have to matt it to get the arc to stabilize. I'll post a couple of pics when i get the chance. Im a little behind myself today and for the next few days...


TacMig, Thanks alot. I'l look forward to that. finished 'em yet? Im still waiting...

Will do Bert. Thanks.

Ok
One: There is no frequency control on a Syncrowave 200. All you have in the way of wave form adjustment is the balance control but it is only a minor adjustment 60/40 max
Two: The power curve on the pedal is not linear. So half pedal is not half power as set on the front of the machine. I never use the pedal to completely readjust my power I just set the amps a little more then I need on the machine and back off the pedal a smidge then if I need more heat I mash the pedal down. so I think what you are experiencing is normal for the operation of the pedal.

non linear huh... Hmmm. that explains alot.
I think im going to get the machine checked out. I know something is wrong and since its still under waranty... I amy as well. Pmo though.brand new machine and its faulty.. why do I seem to get all the winners...? Uhg.

you're not the only one to get stuck with a lemon. Just be glad you have a good company to stand behind the product. you should have no problems getting it taken care of.
BTW When the company I use-to work for got that Econo tig It came out of the box with a bum pedal. The pedal had a huge flat spot in it. Hit it to start the arc no problem little more pedal no problem the you keep giving it more and it wouldn't get any more heat then you get past that spot and it was full blast.
It was a pain in the Arse. I hadn't picked up a tig torch in years then we got that machine and it took some time to figure out we had a bum pedal. We bought a new pedal and man what a difference it was like night and day.

Im going to start thinking about a syncro 250 or one of the inverter machines..

Theres a fellow interested in buying my 251 and if so, i'll upgrade to the 252.
Im finding that the sync 200 is not adequate for my needs so with a little more power, I will be able to handle all the 1/4" stuff thats been coming my way lately. The 200 get too hot too quick and Ive found myself having to wait...im not sure about the dynasty's though. Too much price for a bloody cct board and I do some steel now and again.

wish you were a bit closer I'd come up and buy that 251 in a heart beat. I need a new mig I'm saving my pennies for a 252.
