Who it is for
Car body technicians and DIY repairers who fix plastic parts and want to fill cracks with new material instead of only melting the edges together. Handy wherever a wide seam with rod or strip feed is needed.
Who should skip it
Owners of irons above 80 W or with a socket for a shank other than 5.6 mm. For pinpoint work on small parts, a 20 mm working face may be too wide.
