EW Combi Electrolytic Weld Cleaner
Remove Tig Weld Blueing and Discolouration with the EW-Combi Weld Cleaner
The Electrowand EW-Combi weld cleaning machines remove weld discolouration and blueing to leave a clean bright finish on stainless steel tig welds. The EW-Combi gives the option of both a brush or the more traditional pads.
The Weld Cleaning Process
Clamp earth clamp to the stainless steel. Dip the carbon filament brush in the low strength acid solution. Apply the brush to the affected area and the solution allows an electrical current to cross through the tig weld which cleans and removes any contaminants from the affected area.
What is in the EW-Combi Weld Cleaner Kit?
Each kit comes complete with power leads, 2 cable leads (one for brushes and one for the pads), earth lead, spill proof container, 500ml acid, 500ml neutraliser, 2 brushes and 1 pack of 20 pads.
EW Combi Electrolytic Weld Cleaner FAQs
How does the weld cleaner work?
The EW Combi significantly reduces the acid strength needed to remove weld burn by combining a weak solution of phosphoric acid with an electrical current. As the current is applied, the acid works in a very localised area to remove the blueing. If the weld burn is heavy, simply turn the power up.
How do weld cleaner brushes work?
The brushes are made of a carbon filament which carries an electrical current very effectively, so you can get into the tiniest of gaps to remove the discolouration.
Will the EW Combi etch the workpiece?
No. There are many etching machines available on the market for around £4 – 600 so it seemed crazy to us to try and make a dual purpose machine.
What is the difference between the electrowand pads and the carbon filament brushes?
Electrowand Pads - The original tool for use with the Electrowand EW-Combi machine. Perfect for flat sheets with discolouration damage.
Electrowand Brushes - Our preferred option as it gives you better access into those tight corners, reduces the amount of acid used and the carbon filament brushes last many times longer than the pads
How long will they last?
This depends on the electrical current you are working with. A higher current will remove damage quicker but also wear out your pads/brushes faster.
It is important to note that as the Electrowand is a chemical process, no one method is quicker, one simply allows you to have greater control and precision.
What solution do I need to use with an electrolytic weld cleaner?
Electrowand EW-Combi machines require active solution and neutraliser which are available below.
Electrowand Solution - Apply to your weld cleaning pads or electrowand brushes to remove weld discolouration and blueing.
Electrowand Neutraliser - Spray your workpiece after using the Electrowand solution to neautralise any residual acid on your workpiece.
