It was a great year for soldering, I had a normal everyday hakko clone but then I got ts100 and didn't think it could be better then I got this bad boy , no reason plane did that thing can't overcome. I didn't have a fee she couldn't handle. I made my own lithium battery packs and soldered the contacts but decided to spot weld, I used this to join my 4 gauge leads together, melting the solder and tip with no problem. breathtaking.
