B. COPING CUTS
1. Follow directions for square cut and use Knob (V) to move torch “In”
and “Out” for the “COPING” cut.
C. BEVEL CUTS
1. Flanges may require preheating prior to cutting.
2. Position torch horizontally at top of flange to be cut, light torch (preheat
flame) throw Vertical Travel Switch (E) “Down”. This will preheat
flange. Once the tip has passed the flange bottom, stop travel, and
prepare to make upwards cut. (Always cut vertically “Up”). See Step 7 of
“SQUARE CUTS” on page 9.
3. A hand preheating torch may be used on heavy sections.
D. MITER CUTS
1. Miter cuts can be made with the following BEAM RAILS: ARR-9214,
ARR-9236, ARP-9045, and ARR-9046, see page 17. for more detailed
descriptions and capacities.
2. Accurately mark a line where cut will be made on the beam. Install the
BEAM RAIL approximately 8" (200mm) behind this line (The rack teeth
should face away from line). Again as in square cutting, having the
BEAM RAIL parallel to the line is most important! Make adjustments as
required. When the BEAM RAIL and line are parallel install the two “C”
Clamps (Z) to hold down end opposite the magnets.
3. Preheating the flanges before cutting may be required when mitering a
beam. See procedure under “BEVEL CUTS”.
E. CAUTION
1. Be sure the flanges under the BEAM RAIL are smooth and free from burrs,
slag, etc. Any obstruction under the BEAM RAIL results in a crooked cut.
2. Be sure to raise Flange Rail (B) and Torch (BB) to clear top at flange
before engaging horizontal travel!
3. The BEAM BUG III is protected by a Circuit Breaker (J) against electri-
cal malfunctions, or overloads. If the circuit breaker pops, determine
and correct the cause, before pushing in button to reset.
4. If the Torchholder Assembly (H) is bumped or dropped check to see
that it is still parallel to Rail (N) as per Step 3 of “SQUARE CUTS”.
(Periodic checks are recommended to insure square cuts).
