I Need Help Wiring Up A Dynasty 200

[AV8OR]

The Dynasty 200DX came last Friday from B&R Welders via UPS with no external damage to the box and I need some help wiring it up.

We don’t expect to be in this house by next summer so I would like to do the ol "hook it to the dryer plug in the garage" routine. I don’t think I'll be pushing the machine to the max but somewhere I read the Dynasty 200 only needs a thirty-amp breaker anyways. That being said I don’t want to burn down the house by doing this either so is this safe?

Ok the red wire on the Dynasty is for three phase so cut it short, put a heat shrink tube over it and wire it back away from the other wires…done. Now for the other three Dynasty wires green, white and black, that is where I need some help.

Here is a shot of the breaker box. The dryer comes off the double breaker with the black arrow. Those two breakers are in the off position and are each labeled 30.



Here is a shot of the dryer plug



Here is a shot of the backside of the dryer plug’s three wires red, black and white.



Here is a shot of the front of the dryer plug with each wire labeled red (R), black (B) and white (W).



I assume the white wire on the dryer is the ground and the green wire on the Dynasty goes to that white terminal….yes?



Now the next two wires on the Dynasty are black and white:

The dryer’s red wire goes to the Dynasty’s ______ wire.

The dryer’s black wire goes to the Dynasty’s _____ wire.

Thanks for your help!

AV8OR, as long as the ground wire is hooked up correctly, put the two other wires from the welder to the red and black as shown on the dryer jack. You have 220 across those.

please reread picture number 2 (red) should not use because of 460 volt i guess

AV8OR,

While your dryer circuit will work OK, be aware that it is a non-grounding application. The neutral wire is present on the plug instead of a green ground. Connect the Dynasty's white and black wires to your receptacle red and black wires. The red wire in the Dynasty cord should be taped back; it is used for 3-phase power.

You really should use a proper welding circuit with the Dynasty. With the dryer circuit that you have, you'd be potentially sending high freq. through the neutral. You really need to have the proper ground for the high freq.

So what you really need is Dynasty Black to Black on plug - Dynasty White to Red on plug - Dynasty Green to bare copper (ground). Actually the black and white/ black and red are interchangeable. The ground in the correct position is the important connection.

I'd be leary of the high freq running through the neutral. It could affect any electronics in your house (computers, amplifiers, TV's etc)

[Sberry]

How you figure you would be sending hi freq thru the N? If this circuit starts in the main entrance service panel and not a sub its the same as ground. The subs are the place it ca get confused. He might take some green tape and re-mark this white in his outlet box as a green,, in a sub it could be relocated to the ground bar. This machine does not send anything thru the ground wire, its stricktly for faults.

Replace the dryer cord to a 4wire that is required by todays code anyway. Put a 4wire plug on the welder, and dont use the neutral leg. Just double check that the electrical box IS grounded.

[TOMWELDS]

Also, when the 4wire cord is installed on the dryer, in the terminal block, in the dryer, you have to remove the 'bonding strap' that connects the ground to neutral.

I assume the white wire on the dryer is the ground and the green wire on the Dynasty goes to that white terminal….yes?
YES.

The dryer’s red wire goes to the Dynasty’s WHITE wire.

The dryer’s black wire goes to the Dynasty’s BLACK wire.

[TOMWELDS]

On a 3 wire dryer plug, the white wire is NOT a ground, its a NEUTRAL.

[coldfusion21]

he needs 3 wires connected from the welder to the box and thats without a ground. with a ground he should have four correct?

[Charlie in TX]

On a 3 wire dryer plug, the white wire is NOT a ground, its a NEUTRAL.

What the difference between a neutral and a ground? My understanding there is no longer a neutral it is actually a 'grounded current carrying wire'. A ground is a safety device. The only time current should be flowing in a safety ground is during a fault. A 240 volt drier does not use a 'grounded current carrying wire'. It MUST be grounded. The white wire IS a safety ground.

As has been said, connect your green to the white in the wall. Connect your white to the red in the wall. Connect black to black. You will be fine.

[TOMWELDS]

Charlie, it will work but it wont be safe. A neutral is a current carrying conductor that is tied to the ground at the main panel only. Dryers were allowed to use the neutral as a ground up until a few years ago...too much risk of danger. Now dryers must have a 4 wire plug..seperate neutral and ground.

[hankj]

Coldfusion,

The Dynasty hooks up a little different. For 230-240V, it uses L1 (white) and L2 (black) and the green/yllow ground wire. For 3-phase, it uses the L3 lead, which is the red wire in the Dynasty cord.

Tom,,, if this circuit originates from a main entrance panel what difference would the color of the wire be???? Ground and N are bonded, only in a sub would this make a difference. We are adding to the confusion here.
