230 系列（300A）水冷噴槍，配備 7/8"-14 水回流/電流供應接頭、5/8"-18 左手水供應接頭，及 5/8"-18 右手氣體接頭

The 7/8"-14 water return fitting made hookup straightforward, and the torch runs much cooler than my old air-cooled unit during long stainless steel passes. Really solid build quality for the price.

Swapped this onto my rig for a long aluminum job and the fittings matched up perfectly — no adapters needed for the 5/8"-18 LH water supply or the gas line. Ran it at 300A for hours and the head never got more than warm to the touch.

Finally a torch that actually stays cool during long aluminum sessions — the 7/8"-14 water return fitting threads in perfectly and the gas flow is smooth with the 5/8"-18 RH connection.
