weldfueltank explosions need to be nerfed into the ground

[Maegor]

Is this just about their effectiveness against blobs, or how powerful they are in general?
Because the effectiveness of flamethrowers against it seem ok to me, plus blobs can make the fire resistant membranes to counter them.
The explosions going through walls with this large of a radius im not a fan of either, but maybe this could be atleast somewhat improved by reducing the amount of fuel in the tanks.

Every action on a welder costs you 1 unit of welding fuel, and the only application I can think of, which would need enough fuel to justify them containing 4000 units, would be refilling your flamethrowers. 10 times even. Do we really need 4000 units of that, in a mobile tank, about 10 times scattered throughout the station?

Unless I made some mistake while reading the code, you need about 80 units to produce a max size fireball (7x7) and 800 to produce the max size explosion (4x4). So most of those units don't really affect the blast.
