Weldar

''"I believe it states quite clearly in the worker's guidelines that bears are not to be let in the building." "So?"'' -Weldar and Kazooie

Weldar is a half-blind welding torch found in Grunty Industries. He is in the basement in the repair depot, which can't be reached until many tasks have been accomplished. He thinks that Banjo is a bear can't quite tell due to his poor eyesight and states that bears are not to be allowed into the building. Banjo hesistantly replies that he isn't. Weldar then says that he forgot to wear his glasses and might as well fight against Banjo anyway.

First off, Weldar just shoots out fire balls which Banjo and Kazooie dodge. Weldar then tries to suck up Banjo and Kazooie, this is their chance to shoot Fire Eggs or Grenade Eggs into his mouth. Weldar then states to refrain from doing that as he is full of flammable gas. Next Weldar sends out nuts and bolts at the duo, which are easily dispatched. When he is hit again after more sucking, he jumps into the air and drops down to get the bear and bird. After a missed drop, he then chases after them before jumping back to the middle of the room and using the vacuum one more. Weldar then turns on a emergency switch which turns on the cables on the floor. Electricity surges through them, making it harder to avoid attacks. He then does all of his attacks in the same order again. After he is defeated he explodes and his head flies and hits a high voltage box, stopping the fan in the A/C Plant and the connected rolling poles.

Weldar gives the duo a Shock Spring Pad for an exit back to the Industries. They can now get Weldar's Jiggy, located behind the giant fan.

In Banjo-Kazooie: Nuts & Bolts, Weldar's head has been rebuilt and appears as a vehicle part called Weldar's Breath. Mumbo explain's that he found Weldar "..in skip and make him into flamethrower."
