not too &^%$ing impressed ...........

hi there folks , I had bought a canox 250 square wave Tig a while back & always used the the stick option until the other day . I think something is wrong with unit it self . I have a bit  of tig welding experince & know what to look for in weld quality .  Frankly ..............I have never seen a Tig machine produce such horrible results .  Spatters , yes while i weld it spatters & magically gums up the tip . any idea what could be causing this ?
Reply:Switch the crater time off. Hi Freq off. Arc control off ( I think). Are you using a remote or foot pedal?What are you using for shielding gas?UA Local 598
Reply:Almost seems like the leads need switched, I could be wrong.. Someone else should be able to tell you for sure..

Reply:I ran into that one time, the bottle of gas was contaminated, we couldn't even use it with a mig it was so bad!

Reply:Turn the crater time off. Your polarity is right and the HF is where it should be. Then look to your gas as others have said. Grind your tungsten...it's been contaminated. Sounds almost like you're using C25 to try to TIG
Reply:wrong polarity would look  much worse than that, the brown discoloration  tells me somethings dirty..if metals clean as others say suspect the gas.....leaks will draw air in....

Reply:Dangit I think you guys are right, I always forget to turn on the gas....
Reply:wow , Thanks for all the input fellas , Here are some more of the particulars :- crater time , high feq & arc control are turned off-  using argon / carbon dioxide      ( CWS 20 gas ? ) - scratch starting arc ...........I have tried almost everything & it still doesn't improve the quality of weld .thanks for all the input fellas
Reply:you need 100% argon. It will not work with a co2 mix. The co2 will react with the tungsten.Millermatic 252Lincoln 175 plusTA 185tswTA 161stlhypertherm pmax 45Victor torchHenrob torchAn S10 for each day of the week
Reply:you should be using 100 % argon.
Reply:react  with the tungsten ? Thats gotta be it because I have never seen  a tig welder do that before . WOW   thanks Welding web
Reply:I assumed by your post that you have actual tig experience.100% argon is a fundamental."I have a bit of tig welding experince & know what to look for in weld quality ." I was, as well as others, were misled by the above quote.Acquire straight argon, grind your tungsten, try again. Post pics.Tim Beeker.
Reply:Feel free to turn your hi-freq back to start, no reason to turn that off unless you want too.Have we all gone mad?
Reply:That appears to be a decent machine. I read your post as "quite a bit tig experience". Thats not what you posted, maybe I jumped too soon.Anyway, practice with 100% and show us what that machine can do.Tim Beeker.
Reply:That looks like a re-branded Syncro250, ya?  The faceplate is identical to mine.Buy American, or don't whine when you end up on the bread line.

Reply:I forgot to mention Fred's son Chris who also worked their , dare i say it . Better than the old man , really smart & good @ everything he does . I can do almost anything & Chris could do it better than me . Man I hated that !
Reply:. . . and in all that time Fred and Chris never taught you that TIG required 100% argon?? MM200 w/Spoolmatic 1Syncrowave 180SDBobcat 225G Plus - LP/NGMUTT Suitcase WirefeederWC-1S/Spoolmatic 1HF-251D-1PakMaster 100XL '68 Red Face Code #6633 projectStar Jet 21-110Save Second Base!
Reply:Love the Canadian flag! Lots of American flags around, good to see a Canadian one. Get 100% argon and get back to us
