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).

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).
