Proposal for Thermo-chiller used with Arc Welding Machines (Water-cooled) Do you have such trouble? Solved by Thermo-chillers! Since the chiller supplies temperature controlled cooling water, the welding torch can always be maintained at a constant temperature. Oxidization of the shielding gas can be prevented with less temperature increase. Since the temperature of the shielding gas from the torch increases, turbulence occurs which deteriorates the effectiveness of the shielding. Excessive amount of spattering scatters around. Maintains the effectiveness of the shielding, by a stable shielding gas with less turbulence. Reduces the amount of spatter scattering. Maintains the joining strength of the welded portion. Extends the life of the tip. \ Reduces man hours for replacement and cost (Prevents softening of tips.) Unstable conditions, such as undulation of the bead (weld mark). Increase in temperature due to a large current. Stable bead (weld mark). Compatible with large current. Since the torch remains cool, the operability is improved when replacing the tip. Solves trouble caused by insufficient cooling of “welding torches.” When a welding torch reaches a high temperature, it may cause various troubles. The use of a “Thermo-chiller” promotes improvement in the quality, operability and reduces costs. Reduces troubles!
