HEAT SEALERS Answered

Hi guys, gals and robots of course

I am having trouble finding out what type of sealer and the required wattage needed to weld high quality annexe matting which is about 3mm thick x 2 - 6mm all up. It is 98% nylon. I need something with about 600mm long jaws and variable heat and probably 6mm weld width? I would like to make my own as well, quite handy with electrics and mechanical stuff, live in Australia with 240v

Kind Regards Build Stuff
