The 50 amp receptical will not be a three prong receptacle it will be a 3-pole 4-wire grounding receptacle. It will be a 125/250 volt rating NEMA number 14–50R. The red and black wires connect to the X and Y terminals, the white wire to the W terminal and the ground wire to the G terminal.

If you are in north America, black and red go to the main prongs and white to the ground (round prong) . Black and red can be on either main prong.
The 3rd round plug is the ground connection.
Basically, Your ground prong is essential to protecting you from being in contact with an "unsuspecting Live current flow." It eliminates YOU as the primary grounding to whatever your plug is supplying power to, and sends any current flow, manually drawn (like touching it), into the ground prong. Your feet touching the earth acts as a "grounding" process, but with a ground prong; itself alone acts as the ground for you, allowing you to escape the ability to receive external power.
The equipment grounding conductor is attached to the rounded prong in a three prong plug. Electrical work is dangerous, call a qualified electrician to install. Improper wiring could lead to personal property damage, you or someone else being injured or killed!
Answer for UK, Europe and countries running a 50 Hz supply service.A four-prong socket on the generator implies that it's a 3-phase generator.The welder appears to be single-phase load working at 240 v 50 A but provided the generator is rated at 415 v 36 kVA that means it can supply 240 v 50 A on each phase, between line and neutral.Given the voltage and power of the generator an electrician should be employed to identify the socket correctly, do the wiring and ensure earthing is correctly completed. Without this the system is dangerous, someone could get electrocuted.
What you term as a four wire cable is known as a three wire cable in the electrical trade. The ground wire is not counted in the cable set as it is not a current carrying conductor. Turn the power off to the circuit in question. Remove the three prong outlet from the junction box. If you see a red, black, white and bare ground then you have a three wire cable feeding the receptacle. If this is what you see and the purpose of this question is to see if it can be changed to utilize a new four blade recepticle then the answer is yes.

Is it a plastic prong sealed together
The green wire is for ground. You can attach that to any metal part of the frame. The red is the active and coincides with the lefthand prong into the plug and the black in this case should be the Neutral and ciocides with the right prong into the plug as seen standing behind the plug.
Sure i do
Black wire to the gold screw, white wire to the silver screw, green wire to the round or U shaped prong screw.

Be sure that those wires coming from the box are for a recepticle and not a light switch.

To adapt a three prong range cord?æto a four prong outlet you need to remove the screws from the back plate to open the electric access panel. Then, pull out the copper grounding strip attached to the middle terminal. Next, remove the green ground screw from under the terminal block and attach it to the four prong outlet.?æ
