<div dir="ltr">The Styrofoam is just for a mold to lay up the fiberglass for the MBT's so it will never see any pressure and I set the amps just hot enough that there is no smoke emitted which is nice.

Too hot also creates a hardshell melting of the foam.

Subject: [PSUBS-MAILIST] Cutting styrofoam<br>
Date: Sat, 18 May 2019 12:32:55 -1000<br>
<br>
Just addressed something that I have not been looking forward to and it worked great! <br>
I had some thin SS wire laying around so I figured out the length I needed it to be then attached one end to the ground clamp of my welding machine and the other end to my electrode holder, set the machine on its lowest setting ( 10 to 55 amps DC ) then started turning up the rheostat with the wire pulled tight and at 40% the wire started going through the styrofoam like butter! So anyone that has a welder and will be cutting styrofoam in the future, this works great.<br>
