FAAC Welding & Fabrication Nationwide

FAAC Welding & Fabrication: The Tempe Owner’s Guide

FAAC welding and fabrication repair in Tempe typically runs $340-$780 installed, depending on whether we’re repairing a cracked operator mounting plate, rebuilding a bent gate arm bracket, or fabricating a custom strike post from scratch. We stock FAAC-compatible steel stock, MIG wire for 4130 chromoly repairs, and common bracket patterns for the 400, 422, and S800 series operators on every truck, so most Tempe calls are completed same-day. Most owners discover the problem when their gate starts catching at the strike, the operator arm chatters against a bent mounting plate, or a welded joint that held for eight Arizona summers finally cracks through.

Which FAAC Models This Applies To

FAAC operator mounting hardware and gate frame welding needs cluster around three series in Tempe residential installs: the 400 hydraulic swing-gate line, the 422 electromechanical swing series, and the S800 underground articulated-arm systems. The mounting plates differ in bolt pattern spacing, the 400 using a 6.3-inch center-to-center spread versus the 422’s 5.5-inch pattern, and trying to adapt one to the other leaves the operator sitting under torsional load that cracks welds within two seasons.

We match parts by the stamped FAAC part number on the original bracket, usually found on the underside of the mounting plate or cast into the arm housing near the motor coupling. If corrosion has eaten the stamp, we measure pin diameter, bolt spacing, and arm reach, then cross-reference against FAAC’s technical bulletins. For welding repairs, we use ER70S-6 wire on mild steel frames and TIG with ER80S-D2 when we’re repairing chromoly arms on heavier S800 installations. Aftermarket brackets from GTO or US Automatic will bolt to some FAAC arms, but the geometry changes the gate’s sweep arc by 3-5 degrees, enough to misalign a magnetic lock or stress the limit switch. We keep OEM-pattern FAAC mounting hardware in stock and will tell you before we start whether your job needs factory-spec material or if a quality equivalent exists.

Signs Your FAAC Welding & Fabrication Is Failing

• The gate catches or bounces at the closed position. A cracked strike post weld or bent stop bracket lets the gate overshoot its designed close point by a half-inch or more, which strains the FAAC limit switch and eventually burns out the motor capacitor.
• The operator arm chatters or knocks during open/close cycles. A loose or cracked mounting plate allows the entire operator to shift under load; in Tempe’s 118-degree summer peaks, that movement works fasteners loose and wallows out bolt holes until the plate needs re-welding or replacement.
• You see rust weeping from a welded joint or hairline cracks in the gate frame paint. Arizona’s thermal cycling, 40-degree mornings to 110-degree afternoons, fatigues steel at weld boundaries faster than steady climates; the crack you spot today was a stress riser three seasons ago.
• The gate sags on the hinge side and drags on the driveway. Hinge pin welding on heavy iron gates separates when the root pass was too cold or the post concrete settled; we see this on east Tempe installs where caliche soil shifts during monsoon season.
• Magnetic or electric strike fails to align consistently. A bent or twisted gate frame, often from a vehicle bump or rust jacking at a welded gusset, changes the gate’s rest position by fractions of an inch, enough to throw off a precisely set FAAC magnetic lock.

Replacement Cost & What’s Included

Every welding job includes pre- and post-repair photos under Haven Standard Clause 4, a written price before any arc is struck, and our 365-Day Done Right Promise. We quote flat, not hourly, because a 20-minute tack repair and a 3-hour frame rebuild both deserve a number you can budget before saying yes.

DIY or Call Us?

An owner can safely check whether a mounting bolt has backed out or whether the strike plate has visible cracks. Tighten loose fasteners with the gate secured open, and look for rust trails that point to hidden cracks.

Where DIY ends: welding a loaded gate frame or operator bracket without relieving stress first guarantees the repair cracks again, often within weeks. Cutting and re-welding a gate arm bracket changes the geometry enough to misalign limit switches and safety edges. And any repair to a gate with a FAAC hydraulic operator requires bleeding the system afterward, a step most homeowners don’t have the equipment or the manual for. We’ve been called to Tempe jobs where a well-meaning neighbor’s repair held six weeks, then failed catastrophically and bent the operator arm. Name what you found. Name what it costs. Leave the gate better than you met it. For welding and fabrication on FAAC systems, that usually means calling (623) 323-3849 before the crack propagates into the motor mount.
