Welding Wire Size

So size your extension cord wire for minimum voltage drop.

Welding wire size.

Double click on chart to view quick guide for selecting mig wire size and welder amperage for your application. Welding cable size is measured by the american wire gauge awg standard. Better wash in may be a requirement in applications subject to fatigue. Figure 5 is an example of a chart for selecting the proper welding cable size.

The welding cable size chart below includes the wire gauge length of the wire diameter weight technical details and color of available. 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. For efficient performance the nfpa 70 national electrical code 210 19 a note 3 recommends branch circuits be sized to prevent voltage drops exceeding 3 percent. These charts show.

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. Check with your machine manufacturer for any information that may pertain to your welding system. 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.

A quality mig wire is critical in robotic welding applications. Welding machines require their rated input voltage to maintain output welding amperage and duty cycles. Material thickness 024 030 035 045 030 035 045 24 gauge 025. 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.

Other charts are available from cable manufacturers and welding reference books. 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.
