It's simply unpossible for that to work. You need a cooler the size of a grocery cart to keep the torch from melting at any welding currents over 0.5 A.

Yea, I'm joking. I had not thought of an integrated solution like that, but I had thought that something about that size would be fine. It looks like the pump is build into the water block. Those 80mm blowers may be a bit slow/quiet/lowcfm It may be good to get some beefier ones. I'm not sure where you fill that thing at. It may need a reservoir/expansion tank to deal with the water expanding as it heats.
