Syncrowave 250 breaker requirements

admin

I picked up a sync 250 a few days ago. I need to get an outlet installed in my garage for it. Do I really need a 100 amp breaker to run this thing? The garage has a 200 amp panel.Thanks.

Reply:I have a 200 amp panel in my home and ran a mid-1990's vintage Syncrowave 250 for years. It was wired with 6 gauge conductors, and I originally had a 50 amp breaker. I upgraded the beaker to 110 amps as per the owners manual. I never had a problem with the larger breaker, probably because I never ran the machine long enough to interfere with anything else in the house. I wouldn't let the larger breaker scare you off.Miller Multimatic 255
Reply:I have had mine on a 50 amp breaker for about 8 years with no problem. I have only run on max a couple of times for short runs. I’m just a hobbyist and rarely weld over 3/16”.Burt _____________________Miller Syncrowave 250Millermatic 211Miller 375 Plasma Cutter Hobart Handler 12010FtDrillBit.com
Reply:The breaker really isn't the issue. In a circuit dedicated to a welder, the electrical codes allow for the breaker to be oversized relative to the wire size, based on duty cycle. The important thing for your welder is to use 6 AWG wire for the circuit, even with a 100 amp breaker. There is no need or reason to go larger on the wire.
Reply:70 amps works pretty good unless you run heavier aluminum.  I've popped that breaker on my syncrowave 350 with tig aluminum.100 amp breaker hasn't tripped yet.Dave J.Beware of false knowledge; it is more dangerous than ignorance. ~George Bernard Shaw~ Syncro 350Invertec v250-sThermal Arc 161 and 300MM210DialarcTried being normal once, didn't take....I think it was a Tuesday.

Reply:Absolutely massive overkill. Get the owners manual from the Miller website. They recommend 6AWG wire and a 110 amp breaker.
