Especially Developed for
Welding Dirty, Heat-Affected Cast Iron
|
Gives sound welds on
cast iron so greasy and dirty that other electrodes will not
even make bond.
Has these special
features:
- Actually welds
burned cast iron such as furnace grates, manifolds
- Has unique
"Quick Freeze Action" Deposits solidify so rapidly that
defects and porosity do not have a chance to form
- Has coefficient
of expansion and elongation similar to cast iron
- Excellent for
forming bond as a welding base on dirty cast iron
- Perfect color
match to cast iron
Magna 720 is the
finest nickel-free electrode in existence |
