for mepBLITz and EASYkleen PLUS Brush
CRITICAL OPERATOR INSTRUCTIONS for mepBLITz Boot
Boot and work piece have to be saturated with polishing solution to achieve optimal performance. Apply little to no pressure on the boot when in operation. It is the solution that is doing the work. Too much pressure will squeeze the solution out and slow the process. EXCESS PRESSURE = LESS SPEED Do not use a rubbing or scrubbing action. This will not speed up the process. This will wear out the boots. After use, remove boot and clean down the electrode. Put the electrode under a running tap and wipe with a damp cloth (make sure mepBLITz is unplugged). CLEAN ELECTRODE = NO CORROSION
Keep a wet cloth at hand to quench the work piece at intervals to keep cool. Working area can be watered down to soak up and contain polishing solution residue. wash or wipe down work piece when desired finished achieved. QUENCH WORK PIECE
CRITICAL OPERATOR INSTRUCTIONS for mepBLITz Brush
Once the mepBLITz Solution Fed Brush has been commissioned attached and the B50 polishing solution drawn through the hose to the brush tip, the brush is ready for use. It’s recommended that an air movement device is used such as an extractor or fan. Ensure B50 solution (red) is drawn through to brush tip. Use Brush with or without bristle splay sleeve. If using sleeve slide high temperature sleeve over bristles and ensure 20mm of bristle are not covered/exposed. Take care adjusting or removing sleeve as it will get hot. Apply soaked brush to the weld to be polished/cleaned. Conductivity via the solution maximises cleaning efficiency. If solution is not fed into the brush so it’s well soaked then the bristle filament will be the predominate conductor The brush will get hot in use which will increase speed. Move the brush along the weld in a constant motion. Add solution as needed to maintain cleaning speed. Work vertically when practical as solution feeds all bristles and improves speed. There will be fumes created from application which is predominately water but as temperature increases phosphoric acid fumes may be created which can be irritating to eyes. Do not dilute weld cleaning solution and only use B50 solution supplied. Always dispose of used solution in accordance with local authorities Have a container of water and a wet cloth nearby so once the work piece is at the desired finish it can be washed or wiped down with water.
CRITICAL OPERATOR INSTRUCTIONS for EASYkleen PLUS Brush
Move the brush along weld in a constant motion and only in gently back and forth motion if weld profile requires. As solution is used up in the cleaning process the speed of the cleaning will reduce gradually. Conductivity will initially be via the solution but as amount of solution held in the brush reduces then the carbon filament will be the predominate conductor.
There will be vapour created from application which is predominately water but as temperature increases phosphoric acid vapours/phosphoric pentoxide may be created which is irritating to eyes. If there is no vapor then cleaning is slower and application of solution is needed. Solution will be slowly contaminated by re-dipping brush that contains contaminates cleaned from weld e.g. Iron, Chromium, carbon and fibres from brush so should be renewed regularly.
Have a container of water and a wet cloth nearby as once the work piece is at the desired finish, wash or wipe down with water. Weld Cleaning Solution should be kept in a re-sealable plastic dipping containing that will allow brush to be fully soaked. Any container with chemicals including a dipping container should have class compliant label. Solution should not stain the stainless steel work piece. However staining may occur if hot solution is left to dry on the surface of the work piece and this may result in streaking.
If the solution is left for extended periods on the work piece e.g. days, this may result in light discolouration although it is very hard to notice. Residue solution removes free iron on the work piece effectively passivating. This may appear as a streak or spotting. Avoid this by absorbing solution in a wet cloth or remove by wiping the surface with solution so uniform passivation occurs. Working area can be watered down to soak up and/or contain residue Weld Cleaning solution or spillage as it will dilute readily in water. If solution is running down a work piece it can be absorbed simply with a damp cloth. The solution formula contains citric acid which is an industry accepted passivator and is a chelating agent so also has a role to “sequester” metal iron i.e. The FE ions remain in solution so exhibit diminished reactivity. The brush can be used vertically over a weld which maximizes initial solution application and electrical connection and speed but there will be a slowing of speed and long term higher solution use. The brush can also be used with a more horizontally technique to minimise solution residue/loss. The brushes speed is reduced when laid on their sides
The brushes will deteriorate slowly. The rate of deterioration is a function of heat and current carried by the brush. The heat and current fluctuate depending on the amount of solution used and heat created. The heat created is dependant on the gauge of stainless, weld profile and time spent cleaning the weld.
