Specification :

Electrode Cigweld Cobalarc 750

Rutile type, AC/ DC hard surfacing electrode.
Resistant to hard particle abrasion.
Air hardening, crack free, martensitic steel deposit
Easy arc starting and stable running on portable AC welding sets ( e 45 O.C.V.) .
Developed in Australia

Description and Applications:
Cobalarc 750 is a NEW smooth running, rutile type
electrode specifically designed for AC hard surfacing
applications in the workshop or on the land.
It gives smooth stable arcing on AC or DC welding
machines and is particularly suitable for surfacing with
portable AC welding sets ( with e 45 Open Circuit Volts)
such as the CIGWELD Easywelder.
Cobalarc 750 should be used with a touch welding or short
arc technique and 1-2 layers are recommended for
maximum deposit hardness. When hard surfacing high
carbon or low alloy steel components a buffer or buttering
layer of Ferrocraft 16TXP, 7016 or 7018 is recommended
prior to depositing Cobalarc 750.
Typical applications include the surfacing of agricultural
equipment and components including points, shares, post
hole augers, ripper teeth and tynes etc

Typical all weld deposit analysis:
C: 0.60% Mn: 0.46% Si: 0.75%
Cr: 5.9% Mo: 0.40%

Typical weld deposit hardness:
HRC HV30
Single Layer on Mild Steel 64 800
Two Layers on Mild Steel* 62 750
* Not recommended for multi-pass welding heavier
than 3 layers
