Model 8 Series Weld Heads
The Model 8 series orbital weld heads are designed for fusion (TIG) welding of tube, thin-wall pipe, and fittings through the range of 0.25 in. (6 mm) to 6.625in. (168 mm) OD (outside diameter) and wall thicknesses up to 0.160in. (4 mm). The narrow width of these heads makes them ideal for fitting-to-fitting welds and other limited-clearance applications.
The Model 8 series weld heads incorporate a two-sided clamping mechanism – precision machined and designed to compensate for significant diameter variances while ensuring positive clamping force and concentricity. The insert sizes accommodate an extensive range of applications, and all Model 8 series weld heads are fitted with water-cooling capability – for heavy wall material welding and/or high duty-cycle requirements.
- Fitting support mandrel – to facilitate the welding of short sanitary ferrules without pre-tacking
- Bench mount bracket – to provide secure support when not in use or when bench welding
- Clamp inserts – available in imperial and metric sizes, as well as non-standard sizes for custom applications
- Extension cables – available in 25 ft. (7.6 m), 50 ft. (15.2 m), and 75 ft. (22.8 m) lengths
Model 9 Series Weld Heads
The Model 9 series of orbital weld heads are designed for fusion (TIG) welding of tube, pipe, fittings, or other cylindrical components. Available in eight sizes and three versions, they accommodate diameters from 3/32in. (2.3 mm) to 7.5 in. (190.5 mm) OD, and wall thicknesses from 0.01in. (0.25 mm) to 0.16in. (4 mm). Each weld head fits a wide range of tube sizes via easily replaced, size-specific clamps. These weld heads are compatible with all AMI Power Supplies.
The standard Model 9 incorporates a two-sided clamping mechanism to hold components being welded in line concentrically, minimizing the need for tack welding. Several of these heads incorporate a flip-up viewing window, for easy verification of fit-up. Most Model 9 weld heads are plumbed for water cooling of both the cables and internal weld head components – allowing increased duty-cycles.
Cooling Units - Fusion
Water-cooled weld heads hold numerous advantages for orbital welding systems on the modern market. Featuring a heavy-duty pump and a flow sensor, these weld head cooling units from AMI attach to the base of the Power Supply. Powered by an outlet in the mating power supply, this configuration provides a recirculating coolant source. Look no further for a reliable cooling unit designed for heavy-wall tube/pipe and/or high-duty cycle welding.
SEC has weld head cooling units available for your specialized applications. Reach out to us today with any questions about specifications, quotes, or compatible products. Our team will provide the knowledgeable expertise you need to help you select the most suitable equipment in the industry.
Remote Pendant – Fusion
Remote welding pendants (RP) allow complete control of all welding functions before, during, and after the actual weld cycle. Use the remote welding pendant to make any changes to the welding program before beginning a cycle if needed. Start the weld work location—not the power supply. Monitor the weld cycle and at any time during the weld if needed. Depending on the system being used, you can also change your weld programs, data requirements, etc., from the RP. Uncover more about these high-quality RPs available at SEC below.
- Touch Screen Graphical Display
- Select from the library of weld schedules
- Compatible with the M217 & M217P Weld System Controllers
- Operates the “New” Dual Weld head Controller
- Integrated Flashlight
