Unfortunately in the US and Canada, we do not have a standardized 220v outlet yet. As such, different shops may have different outlets, independent of the location or age of the building.
To help make things easier, we offer an adapter for the most common plugs. We sell these at our cost in order to help our customers out. Additionally, if you tell us what plug your shop has when you place your order, we will provide you with the correct harness free of charge.
If you cannot find the right plug that fits your shop, please feel free to call us at 844.258.7457 or email us at firstname.lastname@example.org
