Okay, now that I won the auction for the Syncrowave 350, I'm going to be needing to get heavy duty wiring and have the house's breaker boxes upgraded. Hint, hint, the welder needs to be hard-wired to 240VAC 1phase.

For how many rated amps should I get the breaker for this welder? I'm also looking at getting a plasma cutter that can cut up to 1/2 inch steel. How many amps would this draw, volts, and what kind of breaker would I need? If the electrician is coming out already, I might as well be prepared.

 

that welder can max out at like 150 amps. if your only doing tubing and stuff under like 3/8 inch youll need 80-100 amp breakers.

 

Um.. Please tell me you know what your talking about.

I thinka 50 amp breaker would be more than enough. Readthe welders input specs. Chances are 30amps @ 220v is fine too

 

make sure u can pull the amps through the wires to the house though... i hope u know u cant just upgrade breakers especially the main without upgrading the wires coming in... which can get pretty expensive... if u do know this.. just read the manual and it will tell u how big of a breaker u will need

 

Read the manual. If you don't have one, go to the Miller site and download it. That'll tell you the input current (output current is basically meaningless.)

If you don't know what size wire to use it would be a good idea to have an electrician do it.

Based on the page listed above, it says 120amp input. It likely won't need this in reality, unless you're running it really hard for extended length of weld...but I'd reccomend going ahead with a 125 amp breaker.

I wired in a complete fuse box in my garage, which has power for compressor, and more... You can buy the full boxes, sometimes with breakers in them already, for less than a smaller box and a couple breakers....especially if it's an indoor rated box. Outdoor boxes are a bit more expensive. Also, check into the wires used to wire main power supply for mobile homes. It's aluminum, rather than copper, but they are larger to make up for it. You can buy them as a set (all 3 cables together) by the foot and probably save a lot of money that way.
