Materials and wires included in the calculator
| Material | Wire selection | Typical gas |
|---|---|---|
| Carbon steel | SG2 / G3Si1 / ER70S-6 or E71T-11 | Ar + CO₂ (18–20%), CO₂, or no gas with E71T-11 |
| Galvanized steel | SG2 or CuSi3 | Ar + CO₂ (18–20%), CO₂, or Ar 100% for CuSi3 |
| Stainless steel | 308LSi, 309LSi, or 316LSi | Argon-based gas for stainless steel |
| Aluminium | AlSi5 / ER4043 or AlMg5 / ER5356 | Ar 100% |
| Cast iron | Ni, NiFe, or stainless steel wire for suitable repairs only | According to the specific wire data sheet |
| Hardfacing | Build-up, 40–50 HRC, 55–65 HRC, or impact-resistant wire | Ar + CO₂ (18–20%), CO₂, or no gas depending on wire type |
Frequently asked questions
Can you weld without shielding gas?
Yes. E71T-11 self-shielded flux-cored wire can be used for carbon steel. No external shielding gas is required and the gas flow is 0 l/min. DC− polarity is commonly used, but always check the specific wire data sheet.
How many litres per minute should be set?
Typical indoor flow is 10–14 l/min. Higher current or air movement may require 14–18 l/min. Excessive flow can create turbulence.
Which gas should be used for carbon steel?
A versatile choice is Ar + CO₂ (18–20%). CO₂ can also be used, but it usually produces more spatter.
Which gas should be used for aluminium?
Ar 100% is most commonly used. An Ar/He mixture may be used for thicker sections.
Do Pulse parameters work for all machines?
No. Exact controls and program structures differ between manufacturers.
