Note:
One-off success is better
for welding, aluminum melt Rotary cutting tool is too low, the second
heating, aluminum pipes deform easily.
Electrode must be evenly flux in order to ensure the quality of solder.
Torch flame cannot be too long, and you must use the proper temprature heat or dispersant aluminum tubes very easy to melt.
Welding, special paste
for nylon two or three minutes after cooling of the pipe cement
repository access, otherwise the solder easy to leak.
Welding time is not too
long, because the melting point is too low for too long can easily lead
to aluminium pipe melted or thinned, suppressed easily leaked.
Liner must be placed wet
towels, protection in place because welding space is very cramped, so be
sure to pay attention to protection of a refrigerator
Can't use torch first heated and then dipped in welding electrode powder, because the electrode melting point is too low.
