Default Square Wave inverter using SG3524N

Hello engineers, I am I newbie, want to make an inverter. I am following the tutorial at http://www.instructables.com/id/250-...ower-Inverter/

I was able to setup the driver stage successfully, but I am having problem with the power stage of the schematic. I used 4 Ń-channel mosfet MT3205 connected parallel, i.e. two on both sides from the driver stage.

The problem I'm having with my circuit is that, the moment I connect the battery terminal to start the inverter, the wire I use to connect the source of all the mosfet to the negative terminal of the battery will burn immediately.

When I noticed this, I increased the thickness of the wire and retest again, and now, immediately I connect the battery to start the inverter, the mosfet will get overheated immediately and get burnt instantly.

The 3524 schematic has a poor gate driver circuit.
