Fuels tanks to refill welders

[atomic1fire]

I know, right? I thought they'd do that around the first time I found them, then I was really confused as to why they wouldn't. Right now, they're mainly just useful for making flamethrowers, storing buttloads of hellchem, and blowing up in the shuttle.

Perhaps, even, it could be attached to the welder to give it an extra 400 units of fuel to burn. Or, it would auto-feed into the welder if held in your other hand or worn on your back. Hmmm.....

Make it a backpack that only accepts fuel tanks and lets you refill by clicking a button.

Refilling while the flame is extended is probably a bad idea.

Of course I have no idea what people are doing if they need to carry a welder refilling backpack around, unless it's fighting kudzu or blob.
