The legth of the gas nozzle can affect the MIG welding process because it modifies the "electrode extension" or so called stickout. The longer the nozzle the longer electrode extension needed to keep the arc away from it thus the value od the welding current and arc voltage changes. These changes will have a great effect on the weld.
Yes, but you need to get hold of the correct small nozzle.

the simplest engine that is made up of a burning chamber and a nozzle is a rocket.
Rocket engine.
rocket engine seems to be of this type. as the air-fuel mixture is burned and flame is made to propogate through nozzle to provide thrust
Heat in plasma arc welding (PAW) transferred arc mode is generated by the arc that is established between the electrode and the workpiece. The orifice gas inside the constricting nozzle is then heat and ionized by the arc. The ionized gas is in the form of plasma and is sent out of the constricting nozzle in a concentrated, cylindrical shape. Thus, creating temperatures greater than 10000 degrees Celsius. This process is very similar to gas tungsten arc welding (GTAW).
