How do I set up the Miller Spectrum 875 after delivery?

First, register your product at Millerwelds.com/support/product-registration. Then install the exhaust pipe and bracket, secure the negative battery cable through the side door, check the oil level, add fresh fuel, verify 18" of clearance on all sides for airflow, and secure the welder to a rigid frame using the four mounting holes. Finally, attach welding cables/connectors to ensure direct contact with the copper bar on the output.
