How to Read the Numeric Cipher

Alright, imagine you’ve got your welding rod, and it’s like it’s speaking in numbers. What’s the deal with those digits? No worries, fellow welder! We’re here to make it simple and break down each number’s meaning one by one. 

1. Diameter – The Big ‘0s’ 

The first number you’ll encounter is all about size, and in welding, size does matter! This mighty digit denotes the diameter of your welding rod.

Picture it like this – if it’s a 6010 rod, the ’60’ signifies it’s 1/16th of an inch in diameter. If it’s a 7018, you’re looking at a rod with a 1/8-inch diameter. Easy peasy, right? 

 

2. Position Matters – The Middle Digit 

Now, let’s turn our attention to the middle child of the number trio. This digit indicates the rod’s intended welding position. Is it all-position-friendly, or does it prefer a specific stance? Let’s crack the code: 

• 1 and 2: All-position welding. These rods are versatile and suitable for horizontal, vertical, and overhead welding. Flexibility at its finest! 
• 3: Specifically for flat or horizontal welding. Keep it grounded! 
• 4: Reserved for overhead welding. If you’re reaching for the skies, this is your go-to. 

 

3. Current Type – The Last Digit 

Last but not least, we’ve got the third digit, which unveils the rod’s preferred current type. It’s the electrical current that makes the magic happen, so pay attention: 

• 0: Can be used with either AC or DC current. Versatility is the name of the game. 
• 1: Exclusively for DC current. Keep the power flowing in one direction! 
• 2: Designed for AC current. Embrace the alternating flow of energy.
