powertig 250ex with water cooler problem

[DisWeld]

I have recently purchased the powertig and water cooler combo unit and the receptacle on the back of the machine does not fit the plug that came with the water cooler. Is there an adapter I was supposed to get that didnt come with the machine? I want to the local hardware store and cant find one. How do I fix this?

You will need to call customer support on this one.

They would know if there is an adapter. Also, the plug on the back of the 250EX, the male end can be picked up at most computer stores. I will see if I can get the name of the connector from digikey.com

Looks like an AT Shrouded male AC plug.

Give sales a call first.

Is your cooler pump unit 220 or 110 volt .Also the plug on the back is the older computer monitor plug style you can get a cord from a computor place and wack the female end off and install a standard 3 prong plug on the cord , Also you can wire the plug to turn on the cooler when welder is turn on since the factory set up on welder is hot with switch off or on position on welder

Same issue on newly arrived cooler and 250ex. I sent Mark a picture of plug sent and receptacle on 250. Waiting for response.

I did notice on 250 plug on welder dose not have the ground lug grounded in welder to case . just the both 110 volt tabs are connected should have the ground lug grounded . also why not have the plug were it turns off when welder switch is turned off instead ove live all the time . I rewired mind so when swich is off or on it turn cooler off and on .

I see on there site the cooler from everlast is 220 Its a really nice cooling unit . alot of other cooler on the market can be 220 or 110 so make sure what the voltage is before connecting to welder ,

Did some net searching. Looks like the needed plug is a standard computer plug IEC-320. And, the welder (250ex) has the receptacle labeled as 220v. The cooler documentation says it is wired for 220v. The IEC-320 is rated at 110v and 220v, just lower amperage at 220v but more than enough for the cooler.

We have recently changed to this 3 prong computer cord style. SOME water cooler units may not match. This is an issue for sales. They will need to know if you get one that doesn't match so one can be drop shipped to you. Best thing to do is email a picture of the plug on your unit and the plug (or lack thereof) on the welder side by side, so they can determine which is best to send you.

shouldnt the cooler turn of when welder is turned off. I moved the power feed for cooler plug to other side of switch on the welder so now my cooler turns on and off with welder on off switch , Darn welder sure welds nice but had some problems with argo and helium mixed tanks getting arc . think i got a bad mix since welder works perfect with straight argon, Thanks all you people at everlast you all are tops in my book on service and support on your product. Will be getting a plasma next month from you all

The outlet on the back should stay live...This is typical for many welders with a service outlet. One reason is that the water cooler should continue to circulate to cool the torch. On other brands that use a 110V outlet, its also used to power things like grinders and drills. Since ours aren't 110V and our US tools aren't 220, it isn't apparent as to the reason why, but that is it. I wouldn't recommend changing anything internally in the unit, but since you did, it is what it is and isn't a serious issue.

Its not bad gas, HF arc starts are always difficult with helium, you should hookup a manifold and then you can get the right mixture for what your doing, also try scratch or lift arc starting.

Dis,

Thanks for the input. I do not use Helium as Argon satisfies my needs...That's something that I haven't done much of except a time or two in testing/sampling and never noticed it.
