If the amp rating on the welder is 47.5 amp then the dryer would be short on power as dryer circuits are 30amp. A range circuit is normally 50 amps and you would be covered.

That said, you need to check the specs on the welder to see what circuit capacity they recommend. 47.5 amp is an odd number for a spec and you may be reading the wrong spec.

Who make the welder?
