WELNY-A-3

GENERAL DESCRIPTION
WELNY WELDING MACHINE IS SPECIALLY DESIGNED FOR THE REPAIR OF ION EXCHANGE FLUORINATED-POLYMERS MEMBRANES.
DEFECTS TYPICALLY PRESENTED BY THESE MEMBRANES ARE MICROPERFORATIONS OR TEARRING THE WORKING PROCESS BECAUSE OF MICROMOVEMENTS PROVOKED BY VARIATIONS IN THE PRESSURE OF THE FLUIDS UNDER TREATMENT.
THE SPECIAL CONFIGURATION HELPS MAKING THE REPAIR SAFE AND SURE, ALSO CONSIDERING THAT MEMBRANES OFTEN WRINKLE AFTER USE. A SPECIAL CARE WAS APPLIED IN ORDER TO OBTAIN A TRASPORTABLE APPARATUS WITH REDUCED OVERALL DIMENSIONS.
THE SHAPE REMINDS US OF A SEWING-MACHINE. A THERMOREGULATED HEATING PLATE, RUN VERTICALLY BY A PNEUMATIC CYLINDER, IS UTILIZED FOR THE HOT-PRESSING OF THE REPAIR PATCH. AFETER A PRESET HEATING TIME, THE CYLINDER RISES AND A COOLING PLATEN IS PLACED UNDER THE HEATING PLATEN; THE WHOLE IS AGAIN FOR THECOOLING TIME.

SAFETY
LOWER VOLTAGE IN ELECTRICAL CIRCUIT 24 VDC.
TWO HANDLE PUSH BUTTON PRESERVE OPERATOR HAND FROM THE CRUSH.
A FENCE PRESERVE THE OPERATOR HAND FROM SCALD.

HEALTH PRESERVATION
TO PRESERVE THE OPERATOR HEALTH, A VACUUM SYSTEM PROVIDE TO ASPIRE OVER AND UNDER DIRECTLY FROM PATCH AREA AND TO COLLECT THE NOXIOUS HEAT FLUORINATED GAS DURING WELDING AND COOLING OPERATION.

WELDING POSITION BETWEEN MEMBRANE, PATCH AND KAPTOR OR WEPAC

WELDING POSITION

TREATEMENT BEFORE WELDING
OPERATE ON THE ANODE SIDE.
DRY THE ZONE TO REPAIR BY PAPER TOWEL.
SPRINKLE WITH ETHYLIC ALCHOOL BY A BUNDLE OF PAPER TOWEL.
BLOW BY AIR GUN THE ZONE TO WELD TO DRY AND TO REMOVE THE DUST RELEASE FROM THE MEMBRANE DURING THE DRY.


STEP-1:THE OPERATOR IDENTIFY AND MARKS THE AREA THAT TO BE REPAIR

STEP-2:THE MEMBRANE IS POSITIONED AND THE OPERATOR PUT INSIDE THE CENTERING PLATE THE WEPAC (OR TRADITIONAL PATCH)

STEP-3:THE OPERATOR PUSH THE TWO START PUSH RED BUTTON

STEP-4:THE WELDING CYCLE START

STEP-5:AT THE END OF WELDING CYCLE THE MACHINE GO IN AUTOMATIC IN THE COOLING CYCLE

STEP-6:AT THE END OF THE COOLING CYCLE THE CYLINDER RELEASE AND GO IN WAIT POSITION

STEP-7:THE OPERATOR PUT INSIDE THE CENTERING PLATE HOSMY INSTRUMENT TO CHECK IF THE REPAIR'S ZONA IS AT TIGHT (OR BY A TRADITIONAL SYSTEM)

STEP-8:IF THE CHECK IS OK THE OPERATOR REMOVE THE CENTERING PLATE TO REPAIR THE NEXT.
