Scope: This calculator returns Lincoln SuperArc L-56 (AWS A5.18 / ER70S-6) published operating-procedure rows for 炭素鋼 ソリッドワイヤ only. Short-Circuit Transfer assumes 100% CO2 shielding; スプレー転移 assumes 90% Ar / 10% CO2 shielding. 極性 is DC 電極 positive for all rows. Other gas blends, transfer modes, wire chemistries (stainless, aluminum, low-alloy, metal-cored, flux-cored), and base-metal alloys require their own vendor procedure tables.

Understanding Your 結果
区間表示の仕組み
Lincoln SuperArc L-56 の Typical Operating Procedures 表は、ワイヤ径と移行モードごとに作業点を3つ公開しています。各点は完全な組です。ワイヤ送給速度（ipm）、電圧（V）、電流（A）、溶着速度（lb/hr）。入力電流が公開された2行の間に入ると、計算機はその2行が挟む送給速度の区間を示します。公開行とちょうど一致すれば、区間はその1行に縮みます。
これらの領域の条件は、100% CO2 の短絡移行用です。短絡移行で 75% アルゴン、25% CO2 を使うときは、電圧を 1〜2 V 下げてください。
Lincoln SuperArc L-56 Product Technical Data Sheet, Typical Operating Procedures 表 footnote (6)
This calculator's encoded values trace directly to the Lincoln SuperArc L-56 Product Technical Data Sheet, an AWS A5.18 / ER70S-6 carbon-steel solid wire. The Typical Operating Procedures table publishes 21 operating-point rows across 7 wire-diameter and transfer-mode combinations (0.030 SC, 0.035 SC, 0.035 SP, 0.045 SC, 0.045 SP, 0.052 SP, 1/16-in SP). All rows are encoded verbatim with per-row anti-fact tests pinning each value.

Independently verified via two byte-identical ホーム Depot CDN mirrors of the same Lincoln document, confirming the procedure table has not been silently mutated since publication. A separate Lincoln content-delivery copy returned the same procedure-table values in a different document layout.
Wire conformance — Lincoln SuperArc L-56 conforms to AWS A5.18 and is classified as ER70S-6. AWS A5.18 specifies the chemistry and 最小 tensile / yield / elongation / impact values for the classification; vendor procedure tables like Lincoln's go beyond the 規格 to publish typical operating points for shop use. Other ER70S-6 wires from other manufacturers will have similar but not identical operating envelopes. This calculator encodes Lincoln's specific published table; substituting a different ER70S-6 wire requires that manufacturer's own procedure data.
Worked Examples
参照照会3件
確認 your inputs against these reference lookups. All three use the encoded Lincoln SuperArc L-56 Typical Operating Procedures rows.
Example 1 — 0.035 wire, 175 A. Matches Lincoln's published Short-Circuit Transfer row for 0.035 in (0.9 mm) at 250 ipm / 22 V / 175 A / 4.0 lb/hr exactly. In-range badge: yes (Lincoln SC envelope for 0.035 wire is 80-175 A). The result card shows all three SC rows for 0.035 wire plus all three Spray Transfer rows (375-600 ipm / 195-275 A) so the user can see the full operating window for this wire diameter.
Example 2 — 0.045 wire, 310 A. Falls between Lincoln's published Spray Transfer rows for 0.045 in (1.1 mm) at 285 A (350 ipm) and 335 A (475 ipm). In-range badge: yes (Lincoln SP envelope for 0.045 wire is 285-340 A). WFS bracket: 350-475 ipm. The result card shows all three SP rows plus, for context, the three SC rows for the same wire (145-200 A, 125-200 ipm) so the user sees both transfer modes.
Example 3 — 0.062 wire, 500 A. Above Lincoln's published Spray Transfer envelope for 1/16 in (1.6 mm) wire, which caps at 430 A (290 ipm). Out-of-range badge with guidance to verify against shop WPS or contact Lincoln Applications Engineering. The result card still shows all three published rows so the user sees how far above the envelope they are.
Common Questions
質問
What wire 種類 does this calculator cover?
This calculator returns published operating-procedure rows for Lincoln SuperArc L-56, an AWS A5.18 / ER70S-6 carbon-steel solid wire. Wire diameters covered are 0.030, 0.035, 0.045, 0.052, and 0.062 in (1/16 in, 1.6 mm). Short-Circuit Transfer is shown for 0.030, 0.035, and 0.045 wire with 100% CO2 shielding, and Spray Transfer is shown for 0.035, 0.045, 0.052, and 0.062 wire with 90% argon / 10% CO2 shielding. Other gas blends, transfer modes, wire chemistries, and base-metal alloys require their own vendor procedure tables. Stainless steel, aluminum, low-alloy, metal-cored, and flux-cored wires are out of scope. Polarity is DC electrode positive for all rows shown.
Why bucketed ranges instead of a single WFS number?
The Lincoln SuperArc L-56 Typical Operating Procedures table publishes three operating points per wire diameter and transfer mode, each as a complete tuple of Wire Feed Speed, voltage, amperage, and melt-off rate. Lincoln does not state that wire feed speed scales linearly with amperage between published rows, so this calculator does not interpolate between them. Instead, when your amperage input falls between two published Lincoln rows, the calculator brackets your input and shows the WFS range spanning those two rows. Every number on the result card traces back to a specific Lincoln published row. The trade-off is intentional: no fabricated interpolated point estimates, even at the cost of presenting a range rather than a single value. For a single-point estimate, your shop's Welding Procedure Specification is the right reference, not this calculator.
What if my 電流 is outside Lincoln's published range?
If your amperage input falls below Lincoln's smallest published value for the selected wire and transfer mode, the calculator shows an out-of-range badge with guidance to consider a smaller wire diameter or the short-circuit transfer mode if available. If your amperage is above Lincoln's largest published value, the calculator suggests increasing wire diameter. The calculator does not extrapolate beyond published Lincoln data because vendor procedure tables stop where the vendor's tested envelope stops. For amperages outside the published envelope, you are operating without vendor-published procedure data and should consult your shop's WPS or the wire manufacturer's technical support.
Does Lincoln publish curves for other gas blends or transfer modes?
The Lincoln SuperArc L-56 Typical Operating Procedures table publishes Short-Circuit Transfer with 100% CO2 and Spray Transfer with 90% Ar / 10% CO2. Other documented combinations exist in Lincoln's broader literature but are not in this calculator's encoded data. A footnote on the source table notes that when using 75% argon / 25% CO2 for short-circuit transfer, voltage should be reduced by 1 to 2 volts compared to the 100% CO2 values shown. Pulsed spray transfer (GMAW-P) is a separate process with its own waveform-specific procedures not covered by the steady-state table this calculator references. For other gas blends, refer to the Lincoln SuperArc L-56 Product Technical Data Sheet directly or contact Lincoln Applications Engineering.
Why is 電圧 shown alongside WFS and amperage?
In gas metal arc welding, wire feed speed, voltage, and amperage are coupled by the constant-voltage power-source dynamic, the wire feeder drive ratio, and the electrode extension (stickout). Lincoln publishes operating-procedure rows as complete tuples because changing any one parameter without adjusting the others moves the operating point off Lincoln's tested envelope. The voltage shown is what Lincoln tested at the corresponding WFS and amperage; using a different voltage at the same WFS will shift the actual amperage, which may push the arc outside the documented spray-transfer or short-circuit envelope. For shop use, set the voltage Lincoln shows for the operating point you want, then verify amperage on the power source matches the published value within instrument tolerance.
