splicing aluminum to copper elec wire
I just bought a new oven and it came with aluminum wire and I have to splice it to copper. Do I need to do something different for this connection? I know aluminum and copper doesn't play well toge...

get an electician with the proper connectors. Or if you are handy and do your research, get the right connectors.
I once had an 1981 Lincoln Electric SA 200 portable welder with AL. windings to CU. cables. It was awful, The heat from resistance caused voltage drop, anperage increase burning out the connections.
A constant current (150 ishamp ) variable voltage welder( 28 - 48ish v) SMAW process is a different critter but the same rules apply, When amperes increase the size of the cable must also increase.
Think of it like a mountain waterfall or a slow river. They both move the same amount of water energy over a given distance in the same amount of time. That is the v/a simple definition.
Camps are full of underground AL. cables to AL. bus to CU. wiring to the plug. Even your house likely has AL. wire to the panel.
Applying the rules of electrolytic corrosion between dissimillar metals requires dielectric coatings and weather proof lubricant in enclosures.
In a mobile welder, open to the weather, it failed. In a home or campground with protected enclosures its great. Your issue can be resolved with the right weatherproof, dielectric compatible connector.
