110v outlet

[Chinolbz]

Hi guys. New to posting but I have been lurking for years. I am going to try this area as well. I see that many of the newer 220v welders have a 110v outlet installed on them for coolers or grinders or whatever. How is this accomplished? I have looked at my Square wave 175 and there is no neutral wire. I would like to add a 110v outlet but I don't see an easy way. Thanks!

A 220 is two 110 "legs" feed in.... not really a big deal..... using a multi meter connect your leads (from the meter) one to the center and one to the right / left prong of the receptacle and you will see 110 on each one..... just remember if you are welding and your buddy plugs up the grinder you will trip the breaker as the draw is on one breaker....plus (unless you add it) the 110 rep. wont have a fault protection and could let some magic smoke out

I don't need a neutral?

To accomplish this their is a neutral in the machine which is what gets you the 110. So that means it's a 4 or 5(3 phase or single phase) wire setup,2 hots 1 neutral & ground or 3 hots 1 neutral & ground.

Yes, you need a neutral. Do NOT use a ground to return the unbalanced 120V from a grinder!

The machines that have 120V available, without having a neutral wire in the plug, use a tap off of the transformer inside.

I'm not an electrician, but isn't it pretty standard to have the neutral and the ground tied together in the box? I don't see how it makes a difference.

I'm not contradicting, I'm asking for clarification.
