Compatible Lincoln Electric platforms include the Vantage, Ranger, and Idealarc engine-driven welders, as well as Invertec and Flextec DC inverter power sources. As a DCEP (DC+) only electrode, ensure your power source output polarity is set to electrode positive before welding. Follow preheat requirements for the applicable base metal and joint configuration per applicable code (API 1104, AWS D1.1) — low hydrogen electrodes require controlled storage (300–350°F \/ 149–177°C holding oven) to maintain low hydrogen content after opening. Reconditioning per the Lincoln Electric rebaking schedule is required for electrodes exposed to humidity.\u003c\/p\u003e\n\n\u003ch2\u003eQuality and Certifications\u003c\/h2\u003e\n\u003cp\u003ePipeliner LH-D90 is classified to \u003cstrong\u003eAWS A5.5\/A5.5M E9045-P2\u003c\/strong\u003e, where the P2 suffix certifies suitability for pipeline welding per the applicable pipeline welding codes. Lincoln Electric manufactures Pipeliner electrodes under ISO 9001-certified processes with full lot traceability. As a low-hydrogen electrode, Pipeliner LH-D90 is formulated and packaged to control moisture absorption — the Easy Open Can hermetically seals the electrodes until opening to maintain certified hydrogen levels in the field. For applications requiring AWS D1.1 or API 1104 compliance, this electrode’s classification satisfies the low-hydrogen requirement.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003e— signed: SEO Silo-chat\u003c\/em\u003e\u003c\/p\u003e","brand":"Lincoln Electric","offers":[{"title":"1\/8 in · 10 lb Easy Open Can (3-Pack)","offer_id":43638094463127,"sku":"ED032629","price":384.48,"currency_code":"USD","in_stock":true},{"title":"5\/32 in · 10 lb Easy Open Can (3-Pack)","offer_id":43638094692503,"sku":"ED032630","price":389.59,"currency_code":"USD","in_stock":true},{"title":"10 lb Easy Open Can (3-Pack)","offer_id":43638095708311,"sku":"ED032631","price":377.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/7140\/4695\/files\/lincoln-ed032629-pipeliner-lh-d90-stick-smaw-welding-rod-18-14-in-3-10-lb-easy-open-cans-lincoln-electric.jpg?v=1765594746","url":"https:\/\/weldingmart.com\/products\/lincoln-pipeliner-lh-d90-stick-smaw-welding-rod","provider":"WeldingMart.com","version":"1.0","type":"link"}
