running 110 volt water cooler off of 220 volt input to welder

[WAD]

I have a new job in foundry as a maintenance person. One of the welders is wired to run off of single phase 220. The welder also has a 110 volt water cooler that is presently attached to a power strip. The previous maintnenance guy has run three wires from the 220 volt input (inside the welder) out to a junction box. I guess he was going to use a 220 to 110 transformer between the welder and cooler as an isolation device. Is this really neceassary? I would think that the welder and cooler both have isolation devices in their power supplies, so I was thinking of ru7nning the 110 offf the welder input to a 110 volt plug, so the cooler comes on when the power switch to the welder is turned on. Comments would be appreciated.

Thanks

How many amps is the wire feeding that welder? Makes a difference.

How many wires in that branch circuit feeding that welder? Is there both an equipment grounding wire or metal conduit and a white neutral conductor? You are forbidden to use a green or bare wire or metal conduit as a current carrying neutral.

Is this cooler going to be over fused if tapped from that welder?

There are three wires feeding the welder coming off of a triple 30A circuit breaker. I believe they will be red white and black, but will verify. The wiring diagram for the welder shows a dedicated green ground wire in the welder. I will also check the manual for the cooler to see what its current rating is.

Thanks
