R (a) Set the working temperature of the HOT AIR BLOWER MAX OPERATING
R 370 DEG C (700 DEG F) between 160 deg.C (320.00 deg.F) and 200
R deg.C (392.00 deg.F).
R (b) Cut the welding rod some centimeters / inches longer than the
R necessary length.
R (c) Welding procedure with speed welding nozzle (Step 2):
R CAUTION : MAKE SURE THAT:_______
R - THE TEMPERATURE OF THE HOT AIR BLOWER IS NOT TOO HIGH
R - THE BLOWER DOES NOT MOVE TOO SLOWLY ALONG THE WELD.
R HIGH TEMPERATURES OR SLOW MOVEMENT OF THE HOT AIR
R BLOWER CAN BURN THE MATERIAL.
R 1_ Put the welding rod into the inlet of the speed welding
R nozzle.
R 2_ Move the speed welding nozzle with light pressure and constant
R speed along the groove.
R (d) Welding procedure with hand roller (Step 2A):
R CAUTION : MAKE SURE THAT:_______
R - THE TEMPERATURE OF THE HOT AIR BLOWER IS NOT TOO HIGH
R - THE BLOWER DOES NOT MOVE TOO SLOWLY ALONG THE WELD.
R HIGH TEMPERATURES OR SLOW MOVEMENT OF THE HOT AIR
R BLOWER CAN BURN THE MATERIAL.
R 1_ Put the end of the welding rod into the groove.
R 2_ Point the hot air blower directly at the lifted part of the
R welding rod.
R 3_ Push the welding rod into the groove with a hand roller. Use a
R light pressure.
R 4_ At the same time, move the hot air blower and the hand roller
R along the groove at a constant speed.
R (e) When the welding rod is sufficiently cool, remove the unwanted
