Tender Overview

The Southern Railway (Indian Railways) invites bids for a Portable Single Operated Rectifier Type DC Arc Welding Set suitable for manual arc welding in accordance with IS 4559 (1993) with latest amendments. The procurement references a Capacitor conforming to IS:13340/2012 and requires the equipment to be BIS marked. Project scope emphasizes supply of the welding set with specified performance parameters and electrical ratings, for installation at the Electric Loco Store Depot, Royapuram, Chennai, Tamil Nadu. The contract allows up to 25% quantity variation during and after ordering, at contracted rates, with delivery timelines linked to the original delivery schedule and extended periods. Key differentiators include conformance to IS 4559 and IS 13340 standards, BIS certification, and post-delivery inspection by consignee authorities. The procurement appears to be a supply-only contract with pre-receipt inspection by the Southern Railway consignee. This tender targets manufacturers or their authorized dealers who can produce BIS-marked, IS 4559-compliant welding sets for railway workshop use. Unique clauses include option-based quantity adjustments and GST invoice requirements. The scope also covers installation and commissioning, if covered in scope, with inspection conducted post-receipt at the consignee site. Geographic focus centers on Chennai, Tamil Nadu.
