You size wire by the current. Various insulations are rated for voltage, temperature and the medium where the wire will be run.
The minimum size wire that can be paralleled together stated in the electrical code book is a #3 copper conductor.
The key parameter in sizing wire is the current requirement. Once you know that you can look up value in a wire gauge table. The length of the run is important for longer runs because of the resistance of the wire itself. Aluminum wire requires a larger diameter than copper for the same current. Once you calculate the wire size you can then size the conduit.
You will need AWG #3 if it is a short run.
Depends on the load it will carry which you failed to list.
depends on run load amps. on the outside condenser it will tell you on the spec plate max size fuse.
What kind of heat do you have? Heat Pump? Be glad it runs.
Unplug the electrical outside service connector for the air condenser. Something is miswired.
Possibly a stuck contactor. It is the condenser fan outside the house.
Proper pipe sizing is in the installation manual. The piping should be one continuous run of the same size.
To wire the coil in a Mercury Bobcat: The + terminal goes to the "run" prong on the ignition switch. The - terminal goes to the points and condenser. The middle terminal (the one with the fat wire coming out of it) goes to the center post on the distributor. This is how you wire the coil in any car that has points and condenser. The Bobcats that are little construction machines have diesel engines in them, so there's no coil at all.
The wire size depends on the amperage, not the voltage. The fact that the welder runs on 440 volts does not affect the wire size! You need to ask this question instead: What size wire do you need for a three phase welder on an eight foot run if the nameplate amps are 45A?

The wire size needed for a 180' run depends on the voltage, current, and type of installation. It is recommended to consult the National Electrical Code (NEC) and a professional electrician to determine the appropriate wire size to ensure safety and compliance with regulations.
