Hakko’s G4 blades possess superior thermal performance that makes wire stripping easy. There are three options an operator can utilize, allowing for a solution for almost any application. The G4-1601 blades are straight and long, which works for a general-use type task, not limiting the operator to a specific wire gauge scenario. The G4-1602 blades are used when the wire gauge is between 18 to 28 in size, while the G4-1603 blades are available when the wire gauge is between 26 to 38. These three options give the operator a varied choice in determining which wire gauge size would be best for the task at hand.
