Wide range of applications: You can say all you need to install a fixed place of cotton insulation, can be used, especially in the construction and installation industry. 
 Reduce the process: for a welding insulation nails, so the cleanliness of the ventilation pipe surface without any requirements, eliminating the cleaning process. 
 Save time: up to every minute of the welder welding 20 insulation nails, but welding side edge of pavement cotton insulation fixed, unlike nail insulation adhesive setting time required. 
 Material savings: You can use the coil, so a savings of cotton insulation, and reduces the amount of insulation to use nails. 
 Solid and reliable: Once the welding is completed, insulation nails will not naturally fall off, so as to effectively ensure the construction quality. 
 No shape restrictions: the ventilation tube in any shape on welding, can ensure the construction quality, especially in the circle on the construction of the ventilation tube, better reflect the incomparable superiority. 
 No seasonal restrictions: the construction from welded nails holding the construction site of the temperature limit, any temperature in the winter and welding, will not affect the welding quality. 
 Safe, simple construction: the edge of pavement to the edge of a fixed one-time installation is complete, the construction method, so the construction workers working at height to reduce the time and frequency, the construction becomes more secure, more quickly. 
 Good appearance: the same as the length of studs, so the cotton insulation after welding smooth surface, clean and therefore more suitable. 
 Also: The welder can also serve as repair tools, insulation adhesive bonding is not strong nail and fall off as part of the renovation, the place in the use of exposed ventilation ducts.
