ArtResin Artist's Studio Torch

I purchased this torch and used it one time for about 5 seconds. I am no longer able to get it to light. I have refueled with the butane fuel. Help

For art resin projects. Is there a difference between using a culinary blow torch vs an art blow torch?

What butane do i buy with the studio artists torch? does it use the zippo butane fuel?

Can I use a heat gun? Is a torch really that much better?
