Heavy duty. Great product

I ordered this short $25 HonestRV NEMA 6-50R Female to NEMA L14-30P Twist-Lock Male adapter cord (Amazon ASIN B0DQDR7F77) to run my 220VAC 50-Amp (maximum) welder connected to my 30-Amp (maximum) DuroMax XP5500EH generator in order to weld a broken steel gate, which is hundreds of feet from the home's 220VAC electrical outlets.The actual cord measured only 11-3/8 inches long, but it measured almost 18 inches from tip to tip of the plugs. Being that short is okay though, because it's the safe well-insulated heat-resistant adaptation of the four NEMA L14-30 wires to the three NEMA 6-50 wires which matter (see later for how it's wired internally).The black thermoplastic jacket of the cord is embossed with technical information. It reads, verbatim as "ANHUA [UL] C[UL] STW 3/C 10AWG[5.26mm²] 105°C FT2 600V E313867 100030-765 NINGB" (as can be seen in the attached photos).What does all that mean to you? Well, a lot actually. It's the important stuff. The stuff that keeps you safe.In essence, this embossed alphabet soup technically describes a 3-conductor, 10-gauge, 600-volt, weather-resistant cable designed for heavy-duty use, with specific safety and manufacturing certifications. Did I say 3 conductor? Yes. Even though the NEMA L14-30 is four conductors (phase 1 hot, phase 2 hot, ground & neutral), the neutral isn't used in this adapter. Overall, this is a beautiful cable as it safely adapts the two differing standards which have a different number of wires.But just fitting the cords together isn't everything. We have to consider wattage (i.e., amperage). Specifically, we need to keep in mind that the 30-amp circuit breaker on the L14-30P circuit (which in my case is the DuroMax XP5500EH generator) is the limiting factor. In addition, it is very important to ensure that the equipment being plugged into the 6-50R receptacle does not require a neutral wire, which my Wards Powr-Kraft 230 welder does not require.Unfortunately, the writing on the beginning and end of the adapter are truncated by the end connections, but we can easily piece those two words together given a cross-reference in the UL Product iQ database references the UL file number 100030-765, which is specific to a cable produced by Ningbo Xuanhua Electric Company, so we can see that only the intervening "O XU" is missing from the cable from "NINGBO XUANHUA".The "UL" indicates that the cable is certified by Underwriters Laboratories, a safety organization. The "C" signifies it also has a Canadian UL certification. The "STW" typically refers to a portable service cord, designed for hard usage, with a thermoplastic jacket making it weather-resistant. The "3/C" indicates the cable contains 3 conductors, which is interesting because the NEMA L14-30 plug has four connections, while the NEMA 6-50 has three. The neutral isn't connected. Only the two hots and a ground are connected. The "10AWG" indicates the American wire gauge, which is the thickness of the wires, where 10AWG is a common size for medium-power applications. The [5.26mm²] is the cross-sectional area of the wires in square millimeters (which is an alternative measurement of wire thickness than the AWG). The "105°C" indicates the maximum temperature rating of the cable, meaning it can safely operate in environments up to 105°C. The "FT2" rating refers to a horizontal flame test, and it's a flammability rating for wires and cables. The FT2 test involves applying a 1,700 BTU/Hour flame applied for 30 seconds to a horizontally positioned wire or cable sample to assess the cable's resistance to flame propagation. The "600V" is the maximum voltage rating of the cable, meaning it's designed to handle up to 600 volts. The "E313867" is likely a UL file number, which is likely a unique identifier for the cable's certification, and the "100030-765" is likely a product or manufacturing identification number, likely specific to the Ningbo Xuanhua Electric Company.Whew! Alphabet soup indeed!But it's all important information to know about your cables since you'll be using it to safely adapt the generator output to the welder input, where the biggest mismatch is in the amperage of the two ends even as there is also a mismatch in the number of conductors. To use this cable, you need to know what you're using it for and what the limitations are. In my case, I simply need to ensure I don't exceed the 30-Amp rating of this adapter, which I can accomplish by dialing down the welding duty cycle, as both the HonestRV adapter and DuroMax generator are limited to 30 amps (with the generator having a 30-amp fast-blow breaker to prevent overloads).But what really matters is how much wattage can a 3-conductor 10 AWG Heavy Duty, ETL Listed cord handle?What's a bit confusing about the Amazon listing is that it mentions 125/250V in the attached illustrations, along with 50 Amps and 7600/12500 Watts, but I think this cord is only rated for 30 Amps. (250 V times 30 Amps is 7,500 Watts). That diagram in the Amazon listing is inconsistent because 250 Volts times 50 amps is 12,500 watts, but I think the cord isn't rated for 50 amps. My recommendation is to ignore that 12,500 Watts in the Amazon listing and stick with 7,500 Watts, where the math works out perfectly.In case you want that math, the NEMA L14-30P (30 Amp, 125/250V) plug is designed for a maximum of 30 amps. The 6-50R (50 Amp, 250V) receptacle is rated for 50 amps at 250V. To get the maximum wattage from a L14-30 plug it would be as follows: 30 amps X 250 volts = 7500 watts. This coincides with the product's description of 7500 Watts max. Therefore, I'm skeptical of the 12,500 watt figure in the Amazon diagrams. It's possible that the seller is trying to highlight the potential capacity of the 6-50R receptacle, but then they are neglecting to make it clear that the L14-30P plug is the limiting factor.After all that is said and done, the summary is this is an excellent and safe short cord to connect your welder to your generator so that you can weld all day long (if needed) far from a Mains source of power. For more details, please see the included annotated photos. In explaining all of this, I hope this review helps you make a more informed decision.

The HonestRV Welder Adapter Cord fit well and lets me use my generator and cord with my welder without chopping the end off of a molded cord set to make it work, and at about the same cost as a cord end it's a good deal. It's well built and the handle on the welder plug side is nice as the plug fits tight. It was easy to plug in and both ends fit easily. It allows more flexibility for power sources where a 50A plug isn't readily available.

This L14-30P to 6-50R short extension cord works as intended, providing a flexible connection between the two types of plugs. The cord offers a bit of flexibility, which can be beneficial in certain situations, as opposed to a rigid adapter. The cord was successfully used to power a welder, although the reviewer was unable to validate its ability to handle the full 30 Amps of current that it is rated for. From a technical standpoint, the cord's wiring configuration is as expected: the "W" pin on the L14-30P plug is not connected to anything, indicating that there is no neutral connection on the 6-50 connector. The "X" and "Y" pins provide the 240 VAC power to the 6-50 connector, while the ground is properly connected to the ground. This configuration suggests that the cord is intended for use with equipment that does not require a neutral connection, such as welders or other high-voltage devices. Overall, this L14-30P to 6-50R short extension cord appears to be a functional solution for connecting equipment that requires a 6-50R plug to a 240VAC power source, but users should be aware of its limitations and technical characteristics.

I ordered the Huyang 10 Gage 50 Amp L14-30P Twist-Lock Male to 6-50R Female Adapter so I could use our Twist-Loc Generator Cord to Power our Miller Welder. The Heavy Duty Huyang 10 Gage 50 Amp Male to 6-50R Female Adapter is Very Easy to Use and Very Reliable. I couldn't be Happier with a Product, using the Huyang Adapter really simplified what I thought was going to be a major chore to simply using an Adapter. I gave the Huyang L14-30P Twist-Lock Male to 6-50R Female Adapter a full Five Star Rating Across the Board.

I ordered this to use my welder with my generator for those times when I need it away from the garage. It's not a common need, but as we all know it does happen.My thought out of the box is that this is really well made. It's a heavy cable, with molded plug/receptacle ends. Considering you couldn't make this for the price it's selling for, it's a great value.One word of warning: These are meant for welders, not larger 50-amp appliances. Welders have a lower duty cycle, so plugging a 50 amp welder plug into a 30 amp generator outlet is generally ok. If you try to plug, say, a 50 amp heater into this, you'll likely pop the breaker (hopefully) or start a fire. Use this for it's intended use only!In summary, this fills a very niche need for me very well. I'd absolutely get it again if I needed another one or had a friend/relative with the same need.

I bought a Predator generator from Harbor Freight not long after Hurricane Helene moved through my area. I had already been considering making an adapter plug for my welder so I could do welding work further away from my 240v outlet in the garage then my cords allow. This product is EXACTLY what I needed, and it would have cost me much more to buy the components to make an equivalent adapter! This is a high quality cord and works perfectly. I can confidently recommend this adapter! It is constructed with 10 AWG wire. I would recommend being aware of the ampacity limits and not exceed them. It is sufficient for the light duty welding I do.
