This type has a shape like a knife and is capable of soldering by applying the tip in 3 ways: line, face and point. It is used for soldering at narrow pitches, correction of bridging and drag soldering
Shape J differs from Shape B and I by bending the tip end and is capable of soldering by applying the tip in 2 ways: face and point. It still has a conical/rounded tip and is used for drag soldering and correction of bridging.
This type has a thin conical end and is an ultrafine tip which is best suited for soldering micro components and for repairing narrow/high-density-mounting. However, given the narrow and pointed tip, the heat capacity of shape I is low and may result in insufficient heat being transferred to the workpiece.
If your soldering pot temperatures are inaccurate or if the solder in the pot does not seem to be melting, it is important to check that the settings as well as the condition of the machine. Read on to learn more!
This type has a shape like a flat-blade screwdriver and is capable of soldering by applying the tip in 2 ways: line and face. The width (size of tip) suitable for the workpiece can be selected, and it can be used for any soldering work.
