Electrodes - PROMAX 16LH Low-Hydrogen
Stick Electrode Selection Chart
KEY FEATURES
- Hydrogen controlled, for welding mild & high-strength (carbon-manganese) steels up to 510MPa
- User Friendly: Very Smooth & Stable Arc, Easy Striking, Low Spatter, Easy Slag Removal
- All-Positional (except for vertical down) & excellent weld appearance
- 1kg re-usable pack keeps electrodes in good condition
1KG RE-USABLE PLASTIC PACKS - REDUCES WASTE & MOISTURE EXPOSURE
- Sealed packs keep moisture out, right up to the point of use
- Smaller pack size reduces waste & minimises the time/period of exposure to atmospheric moisture
- Re-usable packs keep unused rods in good condition
WHY IS IT IMPORTANT TO AVOID MOISTURE ?
- Air contains moisture (humidity) and any electrode exposed to air will absorb moisture
- This increases hydrogen levels in the electrode (water 'H2O' contains hydrogen 'H')
- Increased hydrogen compromises the strength & mechanical properties of the weld
- Moisture can also negatively affect the arc characteristics of the electrode
APPLICATION INFO:
- Mining maintenance & fabrication
- Structural steel & site welding
- Rural maintenance
- Pipe construction
- Boilers & pressure vessels
- Build up or buffer layer prior to hard facing
- Single-sided weld joints

FAQs:
Q: Does the sealed pack avoid the need for pre-drying electrodes in an oven?
A: This depends on the application. At the point of opening a sealed pack, 16LH electrodes will almost certainly contain less moisture than electrodes that are not sealed - however electrodes ovens should still be used in critical situations or when specified in the weld procedure.
Q: How many rods per pack/KG ?
2.6mm = approx. 50 rods per KG
3.2mm = approx. 33 rods per KG
