0318113004 - Victor LHF-630 Flowmeter Replacement Adjustment Knob

Don't Let a Broken Knob Stop Your Weld

We've all been there: you're setting up for a critical job, you reach over to adjust your shielding gas, and the knob on your flowmeter either spins freely, cracks, or is missing entirely. It's a frustration that can bring production to a grinding halt. The Victor Knob Lhf630 (0318-1130-04) is your quick, reliable fix to get your Victor LHF-630 flowmeter back in the game. Instead of struggling with pliers to turn a bare valve stem—which damages the brass and makes fine adjustments impossible—pop this genuine Victor replacement knob on and get back to laying beads.

This isn't just a piece of plastic; it's the control center for your shielding gas. Whether you are running pure Argon for TIG or a C25 mix for MIG, hitting that perfect CFH (Cubic Feet per Hour) is the difference between a golden weld and a porous mess. This knob is built with the same rugged quality as your original Victor gear. It features a grip pattern that digs in, so you can tweak your flow rate without taking off your welding gloves. It fits tight and stays put, giving you the tactile feel you need to dial in exactly 20 CFH, or whatever your WPS calls for, without guessing.

Replacing the knob is one of the easiest repairs you can do in the shop, but it saves you the massive cost of buying a whole new regulator setup. Keeping your equipment in top shape shows you care about your craft. A flowmeter with a broken knob is a liability; it's harder to shut off at the end of the day, leading to drained tanks and wasted money. By swapping in a fresh 0318-1130-04 knob, you ensure you're not wasting expensive gas and that your rig is ready to fire up the moment you are.

Designed specifically for the heavy-duty LHF-630 series, this part eliminates the headache of "universal" knobs that never quite fit right. Don't settle for jury-rigged solutions that slip or strip out. Keep a spare in your toolbox or fix that beat-up regulator on the bottle cart today. With genuine Victor parts, you maintain the professional standard your shop relies on, ensuring your gear works as hard as you do.
