6500 gen/ getting 110/220

[flashburn]

im hooking up a 6500 gen to a 200p m/p machine on my truck how can i get 110 and 220 off the gen it has a s/c switch i think sc stands for select current how can i get both at the same time i need to run my 110 compresser for plasma can i tap into a 110 leg going to the 200p and if so will the surge from the compresser cycle cuase problems

Unfortunately,

You can only run one voltage at a time. It will not do both 110 and 220v. Thanks

Hello,

The generators do not allow dual voltage at the same type. The condenser is not setup for that feature.

I have a whole house generator (Genrac 15KW) The generator supplyes 240vac three wire. From either hot leg to the other hot leg is 240vac. From either hot leg to neutral is 120vac. So I always have both 240vac and 120vac. This is normal home wireing. I think the problem is in the total amp draw.

GENERATOR SPECS:
Frequency : 60Hz
Max. AC Output: 6.5KW at 60Hz
Rated AC Out put: 5.7KW at 60Hz
Rated AC Voltage (V) :110,120, 220, 230, 110/220,120/240

200P Specifications:
Operating Voltage:
208/220vac 50/60HZ Input Single Phase 1PH
50amp cut draws 22.7A at 5KVA
40amp cut draws 17.6A at 3.8KVA

A plasma cut at 50 amp will draw 5 kva leaving only .7kw for the compressor. That is 700 watts which is about 1Hp. If you decrease the plasma cutter to 40 amp the picture is better 3.8kva for the cutter leaving 1.9kva for the compressor which is about 2.5 Hp. The peak generator power is 6.5kw the extra 1kw should allow the proper starting of the compressor. You may want to look into a soft start package for the compressor.

Wow, that seems like a major flaw in design. even cheap "home depot" gas generators offer dual voltages simultaneously.

I was considering one of the for a a welding/cutting trailer build but that's no good for me.

I think someone at Longevity does not have the facts on this issue.

That's not entirely true. Kva and kw are different.

That's not entirely true. Kva and kw are different.

The formulas: Watts = Volts x Amps or w=va

K=1000 so Kva and Kw are the same.

I may get chastised for saying htis but if you are going to set up a trailer find you a good portable welder. I have a Lincoln 225 and its great. its also a 10,000 watt gen. You can take your 200P and use it if you need the AC with pilot arc for TIG or you need your plasma cutter. look around and you can find a good used one for $1000 - $1500. I bought mine new and then found 3 diffferent ones for $1000. So look around they are out there.

Kva and Kw are NOT the same.

I have a Diesel generator on a boat that is rated at 18,000watts and 22Kva. They are similar, but definitely different.

The difference between kW and kVA is the power factor. Once again, the power factor, unless known, is an approximation. For purposes of our calculations, we use a power factor of .85. The kVA value is always higher than the value for kW.

kW to kVA kW / .85 = SAME VALUE EXPRESSED IN kVA
kVA TO kW kVA * .85 = SAME VALUE EXPRESSED IN kW

Good point. you have all the welding power you could want really want. I like diesel though!
