I'm going to need to pull the dryer out a bit to see the plug. 30 amps should be good if I get the 140st. Tempted to look at the 160 which might be a bit out of my reach. Given the typical rod sizes and the size of the beads I might weld, 30 amps should be good.Quote:

12 gauge wire would be nice. It would allow you to install 20 amp breakers all around.
My guess is that it's 14 gauge; if so you're limited to 15 amps all around. You can find out from the main panel if it's more convenient.
For your welder, 15 amps at 220 volts is definitely better than 15 amps at 110 volts, although you still won't be able to get the max rated output.
HTH,
rivets
no it has to be center and the breaker in it removed and 1 thin on each side of the new thin 220 center , what get my brother that a electrical contractor is why the install these boxes since a 8 box is like only 20 bucks more . also when he installs wire in new homes he will only install the main box in the garage if they have a garage or out side if the house has no garage , box is better out side so firemen have access to shut power off if a house is on fire . and by code in California 10 is the smallest you can use for a 30 amp dryer outlet house wiring
looking at picture also it amazes me how lazy dry wall guys are when doing a clean job would of only took him a couple of extra minutes to clean around box cover when doing around the box
Yeah. A lot of things in this house they could have done better with very little effort or expense .... *sigh* didn't have a lot options.Quote:

14 ga is for 15 ampQuote:

The problem you will run into, is if you go by the code book you need 10 gauge 3 wire plus ground. You more than likely do not have the 3 wire let alone the 10 ga wire. So you are back to running a new wire.
At the same time I would upgrade the little box into something nicer... Sounds good but the cost keeps going up.
Even if I run new wire into the garage, put in the 220v service and receptacle, I would probably need a 25 - 30 foot extension cable to get it outside where I would want to weld. I'll go 50 foot from the dryer receptacle and call it a day. Learned a lot and that pretty much galvanizes the decision with no second thoughts! :)Quote:
