Most of our welders are engineered and built by skilled American workers who take pride crafting high-precision, highly robust welders. During manufacturing, Sunstone uses parts and materials sourced from U.S. companies whenever possible. In some instances, parts and materials may be sourced from outside the U.S. due to availability and cost. Unavoidably, recent tariffs have increased the cost of parts and materials. To offset the increased cost in manufacturing, beginning May 1, 2025 Sunstone is adding a modest surcharge to affected products. The surcharge for this product is 0.6 and has already been added in to the purchase price. We will continue to monitor tariff costs and will happily adjust these down or eliminate them all together if possible.
