Bro... sometime lighter may not be strong enough. Like i alway teach my frens, use your kitchen stove la (bcos when u do build, you will be at home right?).. lol.. i cfm plus chop the wire will glow red in less than 30 sec while BBQ on the stove
Make sure you have good tension while doing the wraps. And dun worry that the wires opens up aft coiling. No 100% one. Just screw it onto your tank like you would. Heat it till it glow and use your tweezer to press it tight. (warning dun press the wire when it is glowing, you will break the coil). A bit open nvm one la.. Important thing is its work.. Boleh liao..
Lol yeah! Kitchen stove is a damn good idea!
