1/The meaning of“ Hb”:
“Hb” means the max heating temperature of the upper heating. We set the max
temperature at 230°C according to the max temperatrue of lead-free Reweork and
other technical reasons. The data needn’t to be changed.
2/The meaning of “r1” “L1” “d1” “r2” “L2” “d2” “r3” “L3” “d3” ……
