Flux Core Wire Speed And Voltage Chart

Sorting out the best parameters for flux-core wire settings requires a minimum level of experience in that field. Besides, there are basic settings that you can use as the initial point for most of the regular applications. Those basic setting values would make it faster & easier to establish the parameters for applications. Check Best Flux Core Welder Under 200$

For a better understanding of the flux core wire speed and voltage chart, we have tried to bring about a few suggestive plots on several settings in this article. Hopefully, they might help you satisfactorily.

045 Flux Core Settings

The thickness of the welding wire carries much importance & it is no secret. Therefore, a perfect guideline must be followed to understand the proper use of them when it comes to Flux core wire settings. For thicker rods, they usually need higher amperage. Here we have plotted a table for the 0.045 flux core wire setting for flat & horizontal welding positions while mentioning the welding types & ideal Amp/Volts accordingly.

Flux Cored Welding Calculator

The welding calculator makes it easier to find out the perfect wire size & required Volts/Amps once you input the material and other parameters related to it. There are numerous flux core welding calculator tools available that provide complete welding cost review & analysis of the production. Some of the tools can help with seeing the impact of the cost in different aspects of the production as well. Likewise, the increasing rate of deposition & factors involved with arc time/operating. 


045 Flux Core Vertical Settings

For vertical or uphill welding the basic thing that you should do is to increase the wire feed speed. But it is also a basic mistake that happens quite often is trying to move too fast even before the slag dam forms properly. You must avoid doing such things. Besides, the settings for flux core vertical welding is a bit different than usual. Here goes a chart for 0.045 flux core vertical settings depending on several welding positions.

1/16 Flux Core Wire Settings

For different welding positions and welding types the wire parameters happen to be different every time. Just like other wire sizes, for 1/16 flux core wire settings we have come up with a chart having the information regarding welding parameters that might help you.

035 Flux Core Wire Settings

Basically, the 0.035 Flux Core Wire is perfectly suitable to perform the welding on metal bodies with a certain level of thickness. Using this as welding wire on thinner metal would not be a good idea. It is best for the welding metals having a thickness of about 16 gauge or above but below a quarter-inch (¼).

052 Welding Wire Settings

Welding wire with a larger diameter burns hotter and penetrates the metal plate at a deeper degree. 0.052” seems to be a welding wire of that sort which is used for welding much thicker metals. The welding wire settings for it are given below mentioning the welding positions & vice versa.

Flux Core Vertical Up Settings

The parameters/settings of the flux core welding wires for vertical welding positions are quite different than that of the usual positions. Hence, a chart has been plotted right below mentioning the wire sizes and their respective flux core vertical up settings accordingly.

How do you calculate wire feed speed?

You have to multiply the amperage of your weld by the burn rate that is related to the diameter of the wire for calculating the wire feed speed. 

Do you push or pull flux core wire?

With flux core welding one should never push the flux core wire. Rather you should apply a dragging technique. At the weld pool,  the tip of the welding gun should be pointed back and from the completed weld it should be dragged away.  

Can you push flux core wire?

Except for MIG welding, you can not push the wire in the case of flux core welding. Rather you should use the dragging technique. 

Which is better .030 or .035 flux core wire?

When it comes to thicker rods, they need a higher amperage compared to thin rods. Therefore, a .035 flux core wire requires a higher amperage than that of the 030 flux core wire. On the other hand, a .030 flux core wire is best for thinner metals/rods. 


While choosing the welding wire to use you must consider the metal & its thickness. For thicker and thinner metal plate welding wire should be suitable respectively. Along with that, the Flux Core Wire Welding Settings changes depending on the welding positions too. Hopefully, the charts we have provided with proper welding wire Amp/Volts parameters and settings will come to your help.
