Huntingdon Fusion Techniques have incorporated a new argon purging valve arrangement to their Argweld Quick Purge Systems. The old adjustment system has been eliminated, so trial setting is no longer necessary thus saving more time on each weld. To help welders identify the location of the purge systems below the weld joint, where it is normally dark, a high visibility ‘Glo Strip’ has been incorporated centrally between the dams. This ensures accuracy of positioning. Huntingdon Fusion Techniques now has worldwide patent protection on the product range.
