SECTION 4:
WELDING, CUTTING AND
HEATING OPERATIONS
WARNING
DO NOT use the torch handle if grease, oil, flammable
substances, or damage is present! Have a qualified repair
technician clean the torch or repair any damage. DO NOT use
the torch if an internal check valve is missing.
Follow these procedures when performing welding, cutting or
heating operations:
1. Inspect the torch handle for dust, dirt, grease, oil, other
flammable substances, and damaged or worn parts. Remove
dust and dirt with a clean cloth that is free of grease, oil, or
other flammable substances. Check all apparatus used with the
torch for oil, grease, other flammable substances, and damage
before attaching to the torch handle.
2. Inspect the torch head. The tapered seating surfaces must be in
good condition. If dents, burrs, or burned surfaces are present,
have a qualified technician resurface the seat. If you use a torch
with poor seating surfaces, backfire or flashback may occur.
This will damage the equipment or injure the operator.
3. Attach the welding hose to the torch handle oxygen and fuel
gas inlets. Tighten securely.
4. Select the required size and type of tip. Inspect the cone end
for missing, worn, or damaged O-rings (see Figure 5).
