Re: [Electric Boats] Electric 220 to 110 volt Conversion question

 



Short answer is yes, but there are stipulations...
If the 26.+ amp welder is 220/240 (really the same), then you will need to make sure the wiring is up to the task and you have outlets that each use an opposite leg if the 220/240 and both use the neutral of that circuit.  The HFT welder is going to need a 15-20 amp supply.  Each welder outlet should have its own disconnect between the 220/240 line and the respective outlet.  All this being said, you should check with a good electrician that knows the current NEC.  Although some things are functional, there are engineers and bureaucrats that will say otherwise.  I have been an electrician but am not current on the code.

Subject: [Electric Boats] Electric 220 to 110 volt Conversion question

 

I have a question for the group.


In boats sometimes I need to have clean welding done, so i bought a Harbor freight 20 amp MIG wire feed welder ( 60 to 120 amp out).   A friend also gave me an older Dayton brand 26.6 amp input  "buzz box" welder (100 amps out) that both run on 110 volt AC wall plug type input.  Can they be run, one at a time, from a single 220 v. washer / dryer box circuit??  


 I don't think that using the house 110 volt would be safe, not so good for my older home wiring in the country.   The buzz box I will hope to use with magnesium rod,.mostly for steel sheet cutting.  The wire feed machine for building  stuff.  I have a good gas welder/cutter now, but like the MIG option.


I have an extra 220 clothes dryer plug, that might work if I could convert it to 110 safely.  Is there a plug, or a power changing box, with an extension cord, that can go from the 220v to a single leg 110, without having a wiring rework to do ??  Probably some others here have done this change. 


Thanks,  Cal
