It has the thermal dynamics 38 hooked up right now(it was the shop demolition torch). I am impressed with how well it cuts but I am currently looking at the 52 or 102 series so I can get the demo torch back for shop use:awesomework: I will probably go with the 52 being that it is recommended for 1/2" but will severe 1 1/8" and I dont see myself cutting much thicker than that and it can be had for $1500 where as the 102 is $2500.
