The cobra blow torch is handy and shrinks cobra endcaps on the end of cables very fast. Thereby its breezy to use with one hand. At the push of a button the flame gets ignited electronically and thru the regulation of the air supply it can be continuously adjusted from red-orange to blue.
A interlock can block the ignition or turn the flame to continuous duty. To refill the safety blow torch use the valve on the bottom side.
Please use the safety blow torch carefully. In bright surroundings the flame seems to be small but is emitting hot air very far. Do not aim on persons!
