Hi,

I want to make a welding pit, dimensions 22cm X 11cm X 3cm in stainless steel

As a heating element I have this https://www.tme.eu/it/details/kanthal-d-1.20_250/filamenti-resistivi/kanthal/030188-250g/ resistance of Kanthal, to be wrapped around the welding pit ... while as insulation using glass wool or ceramic fiber.

If I use 30mt of 1.2mm thickness resistance with 1.19Ω / m I get about 1480Watt of power ... can it be enough to bring the pond to 400/450 ° C ???

Thanks.
