What Should the Best Welder Extension Cords Have?
If you’re looking for a heavy-duty welding extension cord that can meet all current customer and industry standards, then here are the key features that should be present.
- A 6-gauge copper cable with copper conductors for consistent energy transfer.
- A NEMA 6-50 plug and receptacle as these are an industry standard.
- Insulation that is resistant to both abrasions and chemical exposure.
- It must be UL-listed.
Assuming your welder or your plasma cutter has a 6-50 NEMA plug, then you’ll be able to make use of the extension cord with your equipment. Unless you are planning on extensive outdoor welding or cutting work, most home users can get away with a 25-foot extension cord. This allows you to bring your welding machine to your project.
It is important to note that having the “heavy-duty” description on the extension cord does not automatically guarantee that it will work with your welder. Many indoor/outdoor extension cords say that they are heavy duty, but their 125V rating is only 15 amps, using a 12/3 gauge/conductor. In comparison, most welder extension cords have a 220/240V rating of 50 amps, allowing you to safely use your equipment even though it hasn’t been directly plugged into an outlet.
What Happens If I Use a Standard Extension Cord?
If you use an underrated extension cord to power your equipment, then you are creating a dangerous situation. The result will be an excessive voltage drop, which can cause your welder to overheat and potentially catch on fire. You must not exceed the marked amperage on the cord. Assuming that you do not, then you can plug in multiple extension cords to reach your welding project if need be.
If your outlet is more than 150 feet away, however, you may wish to consider an alternative to your welding arrangement. One single extension cord of 75 feet will carry the current effectively. Connecting a second equal extension cord should still provide an adequate power source for your welder. It is possible to ruin a motor with an extended distance because the length of the circuit creates an amperage drop.
Concerns to Be Addresses with Welder Extension Cords
When you have an extension cord in use with your welding equipment, there are specific safety precautions that must be taken in order to prevent an injury.
The most common type of injury that occurs when using an extension cord is a tripping injury. If possible, you will want to secure the extension cord to the ground in some way. Although duct tape is a common solution, as is placing a rug over the tripping obstacle, these are also potential fire hazards that should be avoided. Look for plastic risers with fire-resistance that you can secure to the ground for the best possible solution.
If an extension cord is covered, then any heat that is being produced cannot escape. This increases the risks of a fire being created.
You will also want to seal any extension cord connections that may need to be made. This set can help to protect the connection on a temporary basis for a pretty affordable price: Click here to view the price on Amazon and get the best deal.
Extension cords should not be run through doorways, ceilings, walls, or floors either.
Although it may seem like common sense, the extension cord should not be modified in any way. Some older cords have four prongs on them, but newer outlets only offer three prongs. Cutting one off so the outlet can fit will likely damage the cord, the outlet, and your welder.
Does Your Electrical Network Support Your Welding?
It is common to have a welder purchase their equipment, including an extension cord, only to find that the circuits of their home do not support the amperage that is required. A standard outlet is typically rated for 15 amps. You will likely need to have a 20-amp rated outlet if you’re running a welding extension cord of 110v.
Most homes do have one 220v outlet that can support your welding equipment. It will either be near where the dryer installation will be. Some dedicated HVAC systems or air conditioning units will also have a dedicated 220v outlet that can be used. Run the extension cord from there to your welder to prevent circuits from tripping on you while you’re trying to weld.
Pricing Options for the Best Welder Extension Cords
You’ll find that the price of an extension cord for welding increases based on the length that you require. The best value in this category is the 25-foot cord, which often retails for $30-$50, depending on the manufacturer.
The 50-foot extension cords for welding tend to be priced in the $45-$75 range. If you need more length, a 75-foot cord is usually priced at $100 or more.
As a rule of thumb, it is a good idea to purchase the largest gauge and length that you can afford.
