Welding wire size.

I think it is the most versatile size wire to use as a welder. 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. Better wash in may be a requirement in applications subject to fatigue. 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.

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. Other charts are available from cable manufacturers and welding reference books. Double click on chart to view quick guide for selecting mig wire size and welder amperage for your application. A quality mig wire is critical in robotic welding applications.

Figure 5 is an example of a chart for selecting the proper welding cable size. 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. Check with your machine manufacturer for any information that may pertain to your welding system. Er70s 6 wire can provide better wetting at the weld toe when compared to an er70s 3 wire.

These charts show. The welding cable size chart below includes the wire gauge length of the wire diameter weight technical details and color of available. The 0 35 would be more suitable for thicknesses from 16 gauge up to inches. View the awg reference table below for dimensions and sizing of welding.

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. Welding machines require their rated input voltage to maintain output welding amperage and duty cycles.
