Our speed welding nozzles come in two varieties: regular and narrow slot. This often leads to confusion.
The designation of ‘regular’ and ‘narrow’ refers to the air outlet at the end of the nozzle. See image at right.
The narrow air outlet concentrates the hot air exiting the nozzle and keeps it away from the surface of the flooring material. This protects delicate floors such as PUR, urethane, or linoleum which are more susceptible to damage from heat.
