Frequently asked questions
Common questions about ESAB from 3G Electric.
What are the as-welded mechanical properties of ESAB Spoolarc 29S ER70S-3 MIG wire?
ESAB Spoolarc 29S ER70S-3 MIG wire provides a yield strength of 72 ksi and a tensile strength of 85 ksi in the as-welded condition. These values are consistent across the available diameters, including 0.030 in, 0.035 in, and 0.045 in. The wire is supplied on steel spools, with net weights of 33 lb or 44 lb depending on the SKU. It is intended for single- and multi-pass welding on carbon steel, including clean or slightly rusty surfaces. Buyers should confirm that these properties meet the requirements of their welding procedure specification.
What is the classification and typical use of ESAB Sureweld 316L stick electrodes?
ESAB Sureweld 316L is classified as E316-16/E316L-16 under AWS A5.4. It is a low-carbon stainless steel electrode with a 1/8 in diameter and 14 in length, packaged in 5 lb containers. As-welded, it offers a yield strength of 62 ksi and a tensile strength of 70 ksi. The low carbon content reduces the risk of intergranular corrosion, making it suitable for welding 316L and similar stainless steels in chemical, petrochemical, and food processing equipment. It can be used in all positions, though amperage settings should follow the manufacturer's recommendations.
What cable length and features are available on ESAB air-cooled TIG torch kits?
ESAB air-cooled TIG torch kits supplied by 3G Electric include models with a 12 1/2 ft cable assembly. They feature a rigid neck and may include a gas valve for table-mounted flow control, depending on the model. For example, the model 26 torch kit (MPN W4014603) and the model 17V kit (MPN W4013802) include a gas valve, while the TXH-201 outfit (MPN 0558102493) is supplied without one. These torches are rated for manual TIG welding on steel, stainless steel, and aluminum. The air-cooled design is suitable for lower-amperage applications where a water-cooled torch is not required.
Can ESAB ER70S-3 MIG wire be used on rusty steel?
ESAB Spoolarc 29S ER70S-3 MIG wire is suitable for single- and multi-pass welding on clean or slightly rusty steel. The wire's formulation and deoxidation elements help tolerate minor surface contaminants, but excessive rust, mill scale, oil, or moisture can lead to porosity and incomplete fusion. For best results, the joint area should be cleaned to bare metal. If the base material has significant rust, consider a wire with higher deoxidizer content or adjust the welding parameters. Always qualify the procedure on representative material to ensure the weld meets mechanical and quality requirements.
What diameters and spool weights are available for ESAB Spoolarc 29S?
ESAB Spoolarc 29S ER70S-3 MIG wire is available in 0.030 in, 0.035 in, and 0.045 in diameters. Spool weights include 33 lb and 44 lb, depending on the diameter and packaging. All variants are supplied on steel spools. The manufacturer part numbers for these SKUs are 1312F04 (0.030 in, 44 lb), 1312F05 (0.035 in, 44 lb), and 1312F07 (0.045 in, 33 lb). When ordering, specify the diameter and spool weight required for your wire feeder and application. 3G Electric stocks these items and can provide additional options on request.
Are ESAB TIG torch kits compatible with standard consumables?
ESAB air-cooled TIG torch kits, such as the model 26 and model 17V, use standard consumables including collets, collet bodies, gas lenses, and ceramic cups. These torches are designed to industry-standard dimensions, so consumables from ESAB and other manufacturers that meet the same specifications are generally interchangeable. However, for critical applications, using original ESAB consumables ensures proper fit and performance. The kits include a 12 1/2 ft cable and a rigid neck. Some models have a gas valve for table-mounted flow control. Always check the torch model and amperage rating to select the correct consumable size.
