In this video Andy reviews the Parkside PT370 gas soldering iron / hot air gun / blowtorch, which is currently available at the Lidl supermarket chain in the UK.
There is flame adjustment, it is a red slider. Also for refueling no adapter is required, but you need to put a rubber gasket on the filler, so it doesn't leak. You can get one from any cigarette lighter. Otherwise it works well.
HEY THERE I USE THIS ONE TOO I CAN SAY THE CAPACITY IF THE INNER GAS TANK IS SO LITTLE . WHAT PIPE DO I NEED TO SCREW IN TO FEED IT WITH GAS FROM A SEPARATE CANISTER ??? THANK YOU
I answer from Germany. Filling with gas is ok as you did. It says (in the German version) in the description max.1 second! in just one short burst. And it would be full as soon as gas leaks out. My question to everyone is: What is the maximum time someone has soldered with one filling?
