Thanks everone, for the help i think its my pedal been using torch switch like zoama said and seems to work ok. I have an ssc pedal from my lincoln 185 tig that im going to see if ssc company can send me the everlast connector for it and if it will work if not i will buy a new one.
Thanks again i will keep everyone informed

Make sure you have only "pedal" selected. Or make sure you don't have upslope/downslope set to anything but zero. Also make sure end amps are set to minimum value.

And clean. clean clean, your work clamp connection (hooking it direct to the metal you are welding as well) and double check to make the cable is tight and clean in the DINSE connector on the work clamp.

Thanks Mark for the reply, the up and down slope is 0 and end amps are as low as it goes and my clamp is tight and grounded good ran multiple passes with the torch switch and it seems like its the pedal, torch switch works good had two start fails on a/c but the arc is alot better and stable than it is with the pedal.

Still having issues on ac side this cant even hold an arc at 5 amps like on dc there is gotta be a problem with the ac side of this machine i bought an ssc pedal and still the arc is horrible shoot out like a flame thrower not always but still the arc is all over not steady like on DC

What is your arc length? Too long an arc can give you fits with low amp AC.

Its 1/8 to 3/16 it can"t start an arc on 5 amps on ac and has a hard time on most amps once it gets going it works but when you let off on the pedal the arc get all weird i tried a soda can and soon as you step on the pedal it burns right through and its on 5 amps max, dc works fine, on ac it just changes tone and jumps all over and if u let off the pedal the arc continues and dosen't shut off some times not always. just got the SSC pedal but did it with the supplied pedal i think its the machine, tried it with torch switch same thing, on high amps it has a hard time starting the arc and keeping it steady also but no always been doing it sense i got it, even tried it on the factory ac settings that come preset same thing it like it can"t get it going. its frustrating because i know its not me but don't know what it is. Thanks
