Both cutters were running and now neither are. 208 volts to plug. Neither will fire manually or by Fireshare. Both worked fine last week off plug. Have been running 30 I Vipercut for awhile and have cut several things and went to start a program the other day ran about two inches and stopped. Wire to plug is 10 gauge. 50 amp plug and 60 amp breaker. Extremely dry air (Hankinson Air Dryer with a Clean sweep filter on it. On Fireshare I can here it click for torch on and off. Running 100psi to line and throttled back to 80psi at the plasma. This first started with the 45 Razorweld plasma. If it would sit it would kick on and be fine. Tried plugging the other in it will not fire by Fireshare or manually. Does it need to be 240 volts to run it??
60 amp breaker is way overprotected for 10 gauge wire This is how you end up burning down your shop. Probably be looking more like 6 gauge maybe even four gauge depending on the distance.
Overprotected basically means that wire could turn into a red hot element and still not trip the breaker.
Most units will list a voltage range that is acceptable for the input voltage. The viper cut 30 manual I found was very vague. I’m wondering if it doesn’t like the 208v .EDIT* hypertherm inverter ones will run with 208 input voltage.
Do you have a standard 240 volt or even a 110 volt outlet you can try your viper cut 30 with?
I tried the 110 volt earlier this morning. Same result. A friend is taking my 45 Razorweld to his shop to plug into his 240 volt.
8 gauge wire sorry not 10.
At least in my area you’re going to be 6 gauge minimum on a circuit with a 60 amp breaker and if you run over a certain amount of feet you’re going to be down 4 gauge. British Columbia has some of the strictest construction rules in the entire world.
Conservative/safe table for wire sizing:
Edit: If it is aluminum wire, it has less ampacity so you will not be able to extend as far as this table shows or need to go to the next larger gauge of wire. Notice the table is trying to limit the voltage drop to 2%.
This shows the drop with aluminum wire. Not saying that you have aluminum but it is becoming more common as the price of copper skyrockets.
A lot of the newer inverter plasma cutters and welders do not like 208 volt.
I can’t blame them. I’m ok at 12V, but much above that I get really fidgety!
I should have been more specific(or less wrong ,
,); hypertherm inverter units can handle 208v easily.
And most units others that are brave enough to list it in their input voltage range specifications in their manual .
But it looks like Everlast units no likey 208
My friend plugged my 45 Razorweld in and it worked fine. They will run with 208 but better on 240 volt. Thanks for your help and answers.
