Hydroflux welder for large pieces

Hello,

I have been contemplating getting a hydroflux welder for quite some
time now. I live in an apartment and am not allowed to have bottled
gas. I make rings, pendants, and bracelets out of sterling silver
and copper 18 to 24 gauge usually) I’m trying to figure out if this
water torch will get hot enough for my soldering needs. It would
really help me if anyone with a hydroflux welder could comment on
how large of pieces they are able to solder with this torch or post
pictures of their work made with this torch. Thanks so much!
