Welding Tips and Tricks

hello guys,
i have a chinese ac/dc 200amp machine. the brand is "jasic".
i think have a similar issue like Jody had in the "3 in 1 Combo Welder Everlast PowerPro 256 Arc Start Fix"
since its a off brand i dont know what the spark gap should be in order to adjust it, is there any rule of thumb? or its about the same in all machines?

thanks

I have no experience with the "Chinese" machines, but they tend to duplicate the name-brands they try to compete against.

Generally, a Miller or Lincoln will have aprox. .008" spark gap. The range I recall for a Lincoln I used was .005-.013, so there is some tolerance.

Good luck,

Do you mean for the HF contacts? I had to give mine a bit of clean/re gap the other day. I just adjusted by trial and error until I was happy, but I'm sure my gap ended up around 0.5mm (0.02")

Yes, the HF contacts was what I was referring to, and I was using numbers from the Lincoln Precision TIG 325 and Miller Synchrowave 250 DX, in particular.

If you got your best results at .020, may I ask what machine? Others with that machine may get bad results with my numbers.

Yeah, the circuitry could be completely different. My welder's from a company called Tokentools, I think they are only in Australia. The owner is a bit of an electrical whiz and specs the machines out himself, but they are put together in China. Mine's an older model of this one http://www.tokentools.com.au/prod55.htm.

Hey,

I must say, I am suprised. I read though the token tools link. Sorry for the hijack but i just thought they fitted into the ol ebay crap category . Guess not. I ll keep them in mind.
