You can but if you get it too hot the diaphram will melt.
Or if a spark goes inside it will burn a hole in the diaphram.

I have an assortment of new ones if it does not work out.

I've done it a few times without any trouble. Weld it in short pulls, and you can quench it with a wet rag to manage the heat.

I used a wire feed MIG and quenched it with a wet rag .
