Frequently Asked Questions
What is the recommended amperage for Perfect Bridge 10-number and 12-number rods?
For 12 Number (2.5 mm), the recommended operating current is 50–90 A for flat welding and 50–80 A for vertical-up or overhead. For 10 Number (3.2 mm), operate at 90–130 A in the flat position and 80–120 A in vertical/overhead positions.
Is Perfect Bridge equivalent to J421 welding electrodes?
Yes. J421 is the Chinese National Standard (GB/T 5117 E4313) designation for rutile-coated mild steel electrodes, which corresponds technically to the international AWS A5.1 E6013 and JIS Z 3211 D4313 standards under which Perfect Bridge is manufactured.
How many welding rods are in a 2.5 kg box and 5 kg box?
A 2.5 kg box of 12 Number (2.5 mm) contains approximately 140 to 150 rods. A 5.0 kg box of 10 Number (3.2 mm) also contains approximately 140 to 150 rods. An 8 Number (4.0 mm) 5 kg box contains approximately 90 to 100 rods.
Can I run Perfect Bridge on a standard single-phase AC welding transformer?
Yes. Perfect Bridge contains potassium arc-stabilizing compounds in the rutile flux that ensure smooth arc ignition and steady re-striking on standard 220V single-phase transformer machines (minimum open-circuit voltage 50V) as well as DC inverters.
How do I request a bulk wholesale quotation or dealer pricing?
