Our new J1772 to NEMA 6-50 adapter makes it easy to plug in and use your welder, or any appliance that has a NEMA 6-50 plug, at all public J1772 charging stations. This adapter works by using a specially designed circuit inside the plug that basically tricks the charging station into thinking a vehicle is connected and ready to charge. This adapter is rated for 50 amps continuous, but please make sure that the charging station can deliver the amperage your application requires. Most public charging stations can support 30 amps or more, and usually have their power rating marked on a label affixed to the unit. This adapter features a J1772 inlet and a NEMA 6-50 receptacle, rated for 50 amps at 250V AC. Weather-resistant and suitable for outdoor use. Super-easy to use – simply activate the charging station as you normally would when plugging in an electric car, then plug in the adapter. The adapter will automatically power on the station, delivering instant power to your tool or appliance. Please disconnect the adapter after use.
