ISIHEAT or ISIHEAT XL TORCH

[candi]

Hello All
I'm new here, what a great forum for tips, ideas and advice!!
I wondered, has anyone had any experience with the Isiheat torches from Germany, made by Herbert Arnold and slightly fettled to be used with oxycons. The XL looks very interesting, designed to work on 2 x 6lpm machines. I would be very grateful if anyone has any info or experience to pass my way on these.
Thanks
Candi
