Weldar

''"Are you a bear?" "Yeah, and you're heading for the recycling plant!"'' - Weldar and Kazooie

Weldar is a half-blind welding torch found in Grunty Industries. He is in the basement in the repair depot, which cannot be reached until many tasks have been accomplished. He thinks that Banjo is a bear, though he can't quite tell due to his poor eyesight and states that bears are not to be allowed into the building. Banjo hesitantly replies that he isn't. Weldar then says that he forgot to wear his glasses, but since he went through the trouble of dragging himself out here (literally, he comes in using his head to drag his body into the room), that he might as well fight the duo anyway.

The Fight
First off, Weldar just shoots out fire balls which Banjo and Kazooie can easily dodge. Weldar then tries to suck up Banjo and Kazooie, which 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 pair, 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. After he is defeated he says that his eyesight is the least of his worries, recommend for a repairman and in a lot of pain. 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.

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