Take control of your MIG Welding! I’ll drop the 🤯 in the comments⬇️

As a production MIG weder who runs hot and fast... thank you!

Amperage is the KEY to Arc Welding. How this applies to GMAW/MIG welding is Very important, as well as diving into some quick research about What You're Actually Doing. It matters! NEVER just twist the knobs to find a Good Sound.
Typical weldable alloys will need 1 amp of energy per 0.001", one-thousandth of an inch of material thickness, to produce a properly fused and complete weld. The Electrode Type & Gauge will have a current carrying capacity and This Info is what we need to control everything. The Wire's Size physically carries the amperage to the weld, & SPEED is delivering the Amps. Find the amperage range of the wire you're using & set your wire speed to produce those amps the correct and calculated way. Voltage is like the pilot light of the arc and will be your control of the arc cone's Shape. DIAL IT IN & Stop running a bunch of samples to "find the sweet spot" or "fry it in".

EXAMPLE]
0.030" solid wire will deliver Amps at a 1:2 Wire Speed
Ratio, meaning every 2 1PM will deliver 1 AMP of Welding Power.
A 1/8" Mild Steel Fillet Weld will need a minimum of
125 Amps to properly fuse the root of the joint and produce a complete passable weld. (1/8"=0.125"
=125AMPS)
After knowing this information and that most fluctuations can range +-20%, I will find the wire sneed and multinly it by 12 to add in the 'failure insurance' This keeps the minimum amperage from falling too low and missing fusion at the root of the weld.
So, 1/8" Steel needs 125 amps minimum, with .030" solid wire at 2x will be 250 Inches Per Minute, and 250X1.2 (+20%) is the Minimum Wire Speed possible at 300 Inches Per Minute.
STAY DIALED!

That chart under the lid changed my life. Didn't have Miller's Auto-Set back then.
