With flowmeter
what it’s used for:
controlling and measuring argon gas flow from a cylinder to your tig or mig welder. you can’t weld without it.
key details from your pic:
1. brand/model: victor - pressure regulator / régulateur de pression. victor is a top us welding gas equipment brand.
2. type: regulator + flowmeter combo
• gauge on the left: shows cylinder pressure in psi and kpa. tells you how much gas is left in the bottle. 0 = empty.
• flow tube on the right: clear acrylic tube with a floating ball. this reads cfh = cubic feet per hour and lpm = liters per minute. that’s your welding gas flow rate.
