1. Using the pull loops, position Opti-Purge in the pipe so that the reflective, glow tape portion in the center of the unit is aligned with the root gap
2. Connect inert gas lines to the BLUE and BLACK hoses
BLUE gas hose is required to inflate the purge bladders
BLACK gas hose is optional to expedite the purging process
3. Turn the gas supply on to inflate the unit and purge the weld zone
Recommended Flow Rate for Purging:
150 CFH (70 LPM)
4. Once a tight seal has been achieved, commence welding while maintaining flow rate
5. After the weld is complete, turn off the gas supply to deflate the unit. Once the
heat zone has sufficiently cooled, remove Opti-Purge from the pipe. Be sure to disconnect
all gas lines and monitoring equipment.
6. Clean Opti-Purge and store in area away from hazardous and sharp objects
