Welding Wire Size
I think it is the most versatile size wire to use as a welder.
Welding wire size. Welding machines require their rated input voltage to maintain output welding amperage and duty cycles. The welding cable size chart below includes the wire gauge length of the wire diameter weight technical details and color of available. Other charts are available from cable manufacturers and welding reference books. The sizes under debate mainly are 030 and 035 they both are a good option but to give you a short answer as a hobbyist welding between 22ga and 1 8 inch the 030 will do the job.
The 0 35 would be more suitable for thicknesses from 16 gauge up to inches. Er70s 6 is also better for creating a smooth transition from the weld to the base metal also known as wash in or tie in. A quality mig wire is critical in robotic welding applications. Awg sizes will have three numbers for example 2 awg 625 30 this means that the welding cable has a total cross sectional area of 2 awg and is made from 625 strands of 30 awg wire.
Material thickness 024 030 035 045 030 035 045 24 gauge 025. Er70s 6 wire can provide better wetting at the weld toe when compared to an er70s 3 wire. These charts show. Check with your machine manufacturer for any information that may pertain to your welding system.
Welding cable size is measured by the american wire gauge awg standard. The important specs to go by when choosing the appropriate wire that is suitable for your applications are the wire gauge amp voltage rating and the length needed. Figure 5 is an example of a chart for selecting the proper welding cable size. So size your extension cord wire for minimum voltage drop.
View the awg reference table below for dimensions and sizing of welding. As an example let s assume you have a 400 amp power source at 60 duty cycle and need a total combined length of electrode plus work cables of 100 feet.
