All values here are orientative starting points. They do not replace a qualified welding procedure (WPS), applicable standards, your equipment manuals or professional judgement. Welding is hazardous: always use certified protective equipment.
MMA / Stick
Electrode diameter and amperage by thickness.
MIG/MAG
Wire, current, voltage and shielding gas.
TIG
Current, tungsten, filler rod and argon flow.
Heat input
kJ/mm per EN 1011-1 efficiency factors.
Power & supply
Breaker and generator sizing for your machine.
Filter shade
Eye protection shade by process and amperage.
Joint preparation
Edge preparation by thickness and joint type.
Guidance derived from EN 1011-1, EN ISO 9692-1, EN ISO 14175, EN ISO 6848, EN 169, IEC 60974-1 and public manufacturer documentation.
MMA / SMAW settings
Electrode diameter and amperage for carbon steel, from plate thickness and electrode type.
Based on manufacturer recommendations (ESAB, Lincoln Electric); classifications per AWS A5.1 / EN ISO 2560.
MIG/MAG settings
Wire diameter, current, voltage, shielding gas and transfer mode from thickness and material.
Gas classifications per EN ISO 14175; wires per EN ISO 14341 / 14343 / 18273; ranges from public synergic charts.
TIG settings
Current, polarity, tungsten electrode, filler rod and argon flow from thickness and material.
Tungsten electrodes per EN ISO 6848; current rules of thumb from manufacturer guidance (Miller, ESAB, Fronius).
Heat input
Arc energy and heat input (kJ/mm) using the thermal efficiency factors of EN 1011-1.
Formula and k factors per EN 1011-1 (process numbers per EN ISO 4063).
Power & supply
Estimate input power, mains current, breaker and generator size for your welding current.
Conventional arc voltage curves per IEC 60974-1; typical inverter efficiency 85%, power factor 0.9.
Filter shade
Recommended eye-protection shade number by process and welding current.
Guidance derived from the EN 169 guide table for arc welding filters.
Joint preparation
Typical edge preparation for steel by thickness and joint type, derived from EN ISO 9692-1.
Simplified summary of typical preparations in EN ISO 9692-1 — the applicable WPS always prevails.
