How can u tell?

 

Based on what I've been reading the past 30min, the weldina and s tune are similar. But the weldina is this more rare version of some sort. And the tips on the s tune are different. (yes I'm aware he go new tips) but the orginal tips that come with the weldina are more oval. This is all based on some threads I've gone through. Not sure if any of this is right.

 

I also think I read that the weldina is quieter too. Once again, not sure if any of this is correct

 

Nice! Thanks for the info then bro! Now im really interested in sound clips!!!
