cause is that welding time is too long or too short. The welding point cannot be
heated for too much time. And the electric iron also cannot be moved away from
the welding point too early. Only when welding tin melts to bright silvery white
can the electric iron be moved away.
2. After welding, please melt a little solder on the welding mouth before putting
the iron back to the frame and turning off the machine. Clean away excrescent
solder on the fiery welding mouth with wet sponge before starting welding next
time.
