    Sam Flande (Distributor)

    “IWSI has been very satisfied with the Capital Weld Cleaners. I have sold several of the 2x40 and a few 1x30 but just last month I sold a CW110 unit. Wow what a machine!!! I have a Freeze Dry plant in my area requiring the stainless to be cleaned and then cotton ball tested so no bacteria can hang up on any surface. This CW110 unit cleans & passivates the customers fabrications for this plant. They use these cleaners and are really pleased. We have good support from Capital Weld Cleaners.”

    Jason Rhodes (Purchasing Mgr.)

    “We have been using Pickling Paste for a number of years to clean our stainless steel boxes… we recently decided to give the 2X40 a try and wish we would’ve “tried” it much sooner. It cut our weld cleaning time by 90%! …paid for itself the first time we used it!”

  • American International Mfg. Co.

    Sean D. (Production)

    “I can up the amperage on the CW110 to Blast through the Weld Cleaning on our 5X4 Stainless Steel Hoppers much faster than anything else! I like using the Pump Gun the most. It gives me a continuous cleaning option that helps getting the job done quicker. The 2X40 unit has the Dual User option and both units have exponentially increased our efficiency.”

  • NewFab, Inc.

    Dan Komulainen

    “We have owned the 2X40 weld cleaner for 2 years and love the quality and price.”

Accelerate Your Post-Processing

One of the most costly and time-consuming shop processes is manual weld cleaning and passivation. Outdated and hazardous methods like pickling paste extend the time it takes to process products to completion.

Capital Weld Cleaner’s electrochemical weld cleaning machines can double or even triple your post-processing speeds, saving you time, money, and sanity.
