Ador Automig MC 70C-6M E70C-6M Metal-Cored Wire
Description
Metal-cored wire for automated carbon steel welding with Ar-CO2
The Ador Automig MC 70C-6M is a metal-cored wire classified AWS A5.18 E70C-6M H4 and EN ISO 17632-A T 46 4 M M21 3 H5. Ador lists good weldability with minimal or no slag, excellent bead appearance, a high deposition rate, suitability for single and multi-pass welding, exceptional mechanical properties at low temperatures, and a best fit for automated and robotised applications.

Typical applications
The data sheet lists welding of carbon and C-Mn steels including fine-grained steels, shipbuilding, boilers, pressure vessels and pipe steels. It also names suitability for joining SA 36/36M (P No. 1) and SA 285/285M Grades A, B and C (P No. 1).
How a metal-cored wire differs from a rutile cored wire
The core is mostly metal powder with little slag former, so the bead is nearly slag-free and multi-pass welds can be laid without chipping between passes. Deposition efficiency is higher than a solid wire because the arc spreads over a wider area of the tubular sheath, giving a broader penetration profile and good sidewall fusion. The compromise is positional limitation: Ador lists flat butt and fillet welds only, so the wire is not intended for vertical or overhead use.
With a low diffusible hydrogen figure under 4 ml per 100 g, the wire helps limit cold-cracking risk on thicker sections, though preheat rules from your procedure still apply. Keep a steady contact-tip-to-work distance and set voltage to hold spray transfer in the 80/20 argon-CO2 mixture. On mechanised carriages, constant travel speed makes the most of the nearly slag-free bead.
For a solid wire in the same C-Mn class, see KISWEL KC-28 ER70S-6; this metal-cored grade is the one to consider when deposition rate and automation are priorities.

About brand
Covered electrodes with names like Celwel, Tenalloy and Supabase are well known to welders who work with Indian-made consumables. Ador Welding, founded in 1951 and based in Mumbai, India, makes welding consumables and welding equipment. Seven Star LLC sources and supplies Ador welding electrodes, TIG rods and MIG wires for fabricators and contractors in Oman, quoting each item by product name, AWS classification and size.
Ador Welding consumables listed here
The listed Ador electrodes and wires are grouped by the steel they join:
- Carbon steel, low hydrogen: Supabase X Plus (E7018 H4R) and Tenalloy Z Plus (E7018-1)
- Cellulosic pipeline electrodes: Celwel 60 (E6010), Celwel 70P (E7010-P1) and Celwel 80P (E8010-P1)
- Creep-resistant chrome-moly: Cromoten (E8018-B2), Cromoten C (E9018-B3) and Cromoten 9M-15 (E9015-B91) for P91
- Weathering steel: Ultracorten I (E7018-W1)
- Duplex and super duplex stainless: Betanox 4462 and Betanox 2594 electrodes, Tiginox 2209 and 2594 TIG rods, Miginox 2209 MIG wire
Where Ador electrodes are used
Cellulosic Celwel grades are used for root and hot passes on cross-country pipelines. Low hydrogen E7018 types serve structural steel, pressure vessels and piping. Cromoten grades are for boiler tubes, headers and steam lines in power and refinery units, and the 2209 and 2594 fillers are for duplex piping in seawater, produced water and process service, which is common in the GCC.
Ordering Ador consumables: what we need
Give the Ador product name and the AWS classification together, the diameter and length, the quantity in kilograms or packets, and the packing you require. Vacuum packing matters for low hydrogen and chrome-moly electrodes. State the welding procedure or code that governs the job and any requirement for impact testing, diffusible hydrogen level, ferrite or corrosion testing. If your client needs a batch test certificate of a defined type, say so at the inquiry stage, because it is requested from the manufacturer for the specific batch.
