So today my 4X4 GS / Accumotive 2 crashed, dislodging the torch and it DIDN'T shut down and kept firing dragging along the metal while completely dislodged. Spoke to Alex and he had never seen that before. I videoed it and got it all. I was hoping I could upload the video here but do not see how. The last couple of jobs the torch dwelled a long time, probably 4 or 5 seconds before firing after initial touch off.
