Risk of damage to a costly LiPo and even worse, of Battery Fire. This is because the chances of an accidental short-circuit are too high with these set-ups. Title: Re: setting hot nichrome wire foam cutter-help needed Post by: nitesh47 on September 11, 2015, 02:58:38 AM Hi kamal,
you are going in the right way, transformer is perfect for cutting as it heats instantly after switch on. Few things to improve as mentioned above use guitar E string, and yes dont forget to add resistant on both the end of the wire. I am using the transformer of an old UPS, aprx 5amp 14v, E string working fine.

nichrome wire is too expensive, now i am looking for element wire furhter if u know any online cheap source of nichrome wire let me know kp Title: Re: setting hot nichrome wire foam cutter-help needed Post by: SI74 on September 11, 2015, 08:29:48 PM But Laptop charger also heats up the E string instantaneously. I asked for the price of such a transformer( built in a box with proper switch and insulation ) , it was 700rs. So I thought of using a charger instead.
Title: Re: setting hot nichrome wire foam cutter-help needed Post by: nitesh47 on September 11, 2015, 09:30:49 PM Bro u r right, laptop charger is suitable.
he already bought that transformer if he havnt then he could use the laptop charger. regards nitesh47... |
