MIG (Flux Cored) Calculator

What material are you welding?

  Steel
 

How thick is the material?

 
All suggested settings are approximate.
Welds should be tested to comply to your specifications.

Gas-Shielded Flux Cored

(Requires the use of an externally
supplied gas or gas mixture.)

Wire Size:

 

Wire Feed Speed*:

 

Amperage Range:

 

Shielding Gas & Voltage Range**:

 

Self-Shielded Flux Cored

(No shielding gas required. Good for outdoor windy conditions. Hotter than solid wires.)

Wire Size:

Wire Feed Speed*:

Amperage Range:

Voltage Range:

*Wire Feed Speed is a starting value only and can be fine-tuned while welding.

**CO2 gas is economical and has deeper penetration on steel, but may be too hot for thin metal. 75% Argon / 25% CO2 is better on thin steels, produces less spatter and better bead appearance.

Settings based on butt welds. Joint design, fitup, backup, position, bead size and stickout may alter conditions.
