Blade Welding
Being able to quickly and safely weld a bandsaw
blade comes in handy for the following situa-
tions:
• to repair a broken blade that is still sharp and
useful.
• to fabricate a new blade from a larger sec-
tion of blade material to fit your bandsaw.
• to re-join a blade that has been purposely
cut for making an internal contour cut.
your metal cutting bandsaw is equipped with a
blade welder that uses electrical resistance to
heat and fuse the blade ends together. this pro-
cess will leave the joint brittle, so it will need to be
annealed to give it strength and flexibility.
The electric current that flows through the
blade welder during operation could cause
serious personal injury or death. To avoid
the risk of electrocution, never touch any
metal part of the welding station during
blade welding or annealing.
To weld the ends of bandsaw together:
1. turn the bandsaw motor OFF.
2. place the blade evenly against the back of
the blade shear and firmly pull the handle
down to square off the blade end (see
figure
32).

blade.
Note: To make a proper blade weld, the ends
of the blade must be evenly butted together
during the welding process. If necessary, use
the grinder to square up the ends or remove
any teeth that are in the welding zone (see
Figures 33–34).
