Question about Cars & Trucks
No, no, don't do that! It's like lighting a cigarette with a blowtorch, a bit much. I'm pretty sure there are some videos on youtube showing homemade injector cleaning set-ups.
You didn't give any information what your injector is in, you know all manufacturers don't do everything exactly alike. Year, make, model, and engine size is how we can make a reasonable response. But FWIW, injectors are usually located in a "fuel rail" or a long pipe, on top of the engine, so that the injector nozzles can be directed into holes that are very near the intake ports of each cylinder. You know, where the intake valve opens into the combustion chamber, at the top of the cylinder, so that air or the air/fuel mixture can be drawn into the cylinder. This is where you would want the injector to spray into: the onrushing air going into the cylinder through the now-open intake valve, drawn in by the piston moving down. The intake ports would be in the intake manifold. In a V-block engine, the intake is in the valley between the two banks of the engine. In a straight 4 or straight 6 engine, the intake manifold is mounted to the side of the cylinder head. Some manufacturers may situate the injectors to spray directly into the top of the combustion chambers, but even those share a common rail to keep gas under high pressure on the injectors. Another type of injection system is called Throttle Body Injection, but that's kind of old style, now.
As to removal procedures, check youtube for your particular vehicle, or better yet, consult a Haynes or Chilton repair manual. Then you have a step-by-step procedure. If you follow it, you can't go wrong, almost never. But never say never.

Make and model would help, the injector should be after the throttle body on the inlet. A welding tip will not even go close to repairing it.
