OPERATING INSTRUCTIONS
4. Plug the Power Cord (W) into an appropriate power source. Pilot Light (Y)
will glow when power is on.
5. Open Torch Valves (EE) throw Quick Acting Manifold (S) lever “Down”
to “Open” position to set fuel gas and oxygen regulators. See Chart (M)
on the side of machine for tip size and pressure vs. thickness.
6. Close Torch Valves (EE), reopen slightly and light - adjust preheat
flame. Turn off preheat with Quick Acting Manifold (S).
7. To make a square cut: (Ref. Fig. 4, 5 & 6).
A. Set Rack (G) in holes on Flange Rail (B) which corresponds to
the thickness of the flange you are cutting. Run BEAM BUG III
out beyond flange and swing torch so tip faces flange.
B. Run Flange Rail (B) downwards until Torch Tip (DD) is slightly
below bottom of flange and stop (use maximum speed).
C. Switch on gases using the Quick Acting Manifold (S) light
Torch (BB), and set cutting speed. When preheat is adequate,
open Cutting Oxygen Valve (FF) [bat handle on torch] and start
vertical travel - adjust speed to suit.
NOTE: As cut comes close to web slow down vertical travel to
insure adequate penetration of web - once past web, increase
travel speed to optimum.
D. When cut has reached the top of flange, turn off preheat gases
using the Quick Acting Manifold (S) and Cutting Oxygen Valve
(FF), limit switch will stop travel.
