Flux Core Mig Welding Wire Speed And Voltage Chart

The lincoln data sheet has charts with recommended settings for different diameters of wire.

Flux core mig welding wire speed and voltage chart.

Unlike welding with a stick welder mig welding is a semi automatic process. For example 030 0 035 0 045 0 068 5 64 3 32. Voltage inches per minute of wire. Self shielded flux cored welding is a wire welding process in which a continuous hollow wire electrode is fed through the welding gun into the weld joint.

Lets assume you are using lincoln nr 233 or another brand of e71t 8 spec flux core wire. Esab 7018 vs hobart. There ll be a minimum and maximum thickness of metals recommended for your particular welder along with specific sizes of flux core welding wire to use. For example for 030 inch wire multiply by 2 inches per amp to find the wire feed speed in inches per minute ipm.

Flux core wire is available in several wire diameters. Sep 02 20 05 18 pm. It looks something like this. If a manual or weld specification sheet is not available use the multipliers in the following chart to find a good starting point for wire feed speed.

The welding itself requires very little skill providing the mig welder settings are correct for the application. Finally once these settings are all put together it produces the transfer type we wanted and it has enough heat to properly penetrate the metal without burning a hole through the joint. A mig welder can typically produce 5 to 8 pounds of weld per hour verses a fcaw welder packing 25 plus pounds of weld per hour. When comparing mig welding to flux core arc welding there is a huge gap in production in the amount of weld per hour.

The information in this article pertain to welding with solid wire. C25 mig welding gas putting the voltage wire feed speed and gas flow gas type all together. Look at which diameters your welder uses. Self shielded flux cored welding differs from mig welding in that it doesn t require an external shielding gas such as carbon dioxide or argon to protect the weld pool from contamination.

A speed that s too high can lead to burn through. Video shows arc shots and tips for tig welding a 3f lap joint on 11ga carbon steel. Flux cored arc welding is the most productive of the manual welding processes.
