New here.. I think I start to understand within a couple hours reading this forum, electrically, I need a contactor which is a basically giant relay right, and a controller, and heating elements?
stealing ideas parts idea from
contactor wiring
I plan on getting a cutler hammer 40amp switch from famousparts
and this same controller from ebay,

My question is, nothing has been built yet, I am wiring up a 40-50 receptable for my welder soon, which will share with the future oven. I am not sure if I need to have neutral in my circuit or not, can't I get 240V version of parts?
240V coil contactor is available, the controller is available in 240V. If I want to add a timer to turn off the controller, does not having a neutral restrict my selection of timer?
Or, should I just bite the bullet and wire in a neutral now? It probably makes wiring a fan in the easier as well because of having 110V?
Next question, if I have 240V, 3100W elements x 2, thats 25.8 AMPS, is a 30 AMP breaker safe enough to use? 30 amps x 80% is 24 amps, which is just slightly under guideline.
