|Application Examples

The following are some of the application examples. Since the amount of heat generated changes with conditions and usage rates, the effectiveness is not guaranteed.

[Equipment] Water-cooled Arc Welding Machine

Specifications	CO₂welding (400 A)
Chiller type	HRS018-A-20-T + HRS-BP001 (Bypass piping)
Application	Welding of construction machinery parts Changed from radiator type to a thermo-chiller.
Effect	The set temperature could be maintained, which extended the life of the welding tip, and reduced costs. ⇒Greatly reduced tip replacement costs

[Equipment] General-purpose TIG Welding Machine

Specifications	Rated output current value 300 A
Chiller type	HRSE018-A-20-T HRSE012-A-20-T + HRS-BP001 (Bypass piping)
Application	Stainless tank welding Changed from radiator type to a chiller.
Effect	Stable water temperature reduced the consumption of the tungsten electrode and power cable. The durability of the collet also improved. By suppressing the increase of the torch tem perature, continuous manual welding became possible.

[Equipment] Water-cooled Arc Welding Machine (Tandem Welding)

Specifications	Tandem CO₂ welding (450 A) + CO₂ welding (400 A)
Chiller type	HRS050-A-20 + HRS-BP004 (Bypass piping)
Application	Thick material continuous welding. Although two radiator types were used conventionally, the improved life of the tip and the cooling system are integrated into one unit.
Effect	When a radiator was used, the water temperature increased immediately after the welding started, and the tip eventually disappeared. After the chiller was introduced, the water temperature stabilized immediately after the welding started, and the set temperature was maintained. The life of the tip was greatly improved. Furthermore, spatter was reduced, and a stable bead formation was obtained.

[Equipment] Plasma Welding Machine

Specifications	Plasma welding machine (300 A)
Chiller type	HRS050-A-20 + HRS-BP004 (Bypass piping)
Application	The cooling of the water-cooled torch used on a muffler plasma welding robot.
Effect	Cooling water at a stable temperature can be supplied even in plasma welding with high radiant heat. The costs of expensive argon gas could be reduced due to turbulence suppression. The wear of the torch tip was also suppressed.
