IMig 140 Power Supply

All,
Thanks for the help on this topic. My breaker box did not have enough room for another 220 so that's why my contractor piggy backed another slot with a 30 amp 115. I wanted a dedicated connection. I agree I would rather be welding with 220, but since I will only be going up to about 1/8 mild steel for most of my projects the 115 should work fine. The company that wired most of the house in my neighborhood is no longer in business. The work they performed was marginal and never should have passed, but sometimes you have to take what you get and make it work.

Sounds like you have it under control. However, don't rule out getting a 240 circuit installed, if you want to upgrade down the road. Depending on the brand, there are half space breaker combos that will let you pull out two single pole breakers and replace them with a combo of one two pole and two single pole breakers. These are great for full panels and I have put in quite a few of them.
Here is an example of what they look like.
