Z-2002 CUTTING AND PIERCING ALL PURPOSE Z- 2100
Dirty, Damp, Galvanized
Or Painted Steel

Description: Description:
Electrodes for cutting and piercing. Usable in all positions. Effective for all types An electrode for general welding of structural steel for surfaces which are damp,
of metals: mild steel, stainless steel, cast iron, nickel base alloys, aluminum alloys, galvanized or dirty (paint, grease, oil, mud). Especially suitable for welding galvanized
armor steels, hard metals and difficult to machine steels. metal parts.
For cutting the electrode should be moved up and down, like sawing , in order to
discard of the molten metal. Uses:
• Galvanized metal sheet.
For piercing the electrode should be positioned perpendicular to the work sheet and • Dripping water pipes.
pushed into the melted steel until it penetrates and then move the electrode up and • General welding.
down until the desired shape of the hole is reached.
Uses: Welding position:
• Cutting metal sheet and pipes.
• Piercing metal sheet l and pipes.
