From the originator of the portable shearwelder, Guild offers the world's most compact semi-automatic shearwelder. The PSA 2000 is ideally suited for small tube mill, roll form lines, and stamping presses.

The unique "C" frame portable design allows this machine to be used for multiple lines regardless of strip flow, cutting it's already low justification cost in half or even thirds.

PSA 2000 EXCLUSIVE FEATURES:

•  A tungsten height gauge is provided that ensures proper setting of the tungsten electrode every time. For proper weld fit up, a built-in automatic gauge bar is provided with our patented split elevating backup bars. Other designs require the operator to manually insert the gauge bar properly and then remove it for every weld.

• Providing properly sized air cylinders for clamping provide over 200% more clamping force than others. These cylinders are mounted at the rear of the machine and preventing damage from strip and allowing the operator more work space during welding. Clamping and shearing actuation is by foot valves so the strip can be held with both hands by the operator.

• Solenoid-operated clamping bar makes for simple automatic torch traverse. (This feature eliminates the need for "Jog Forward" and "Jog Reverse" buttons, forward and reverses weld carriage motor relays, and weld start limit switch). Additionally, torch acceleration is instant and without slip.

• Pneumatic powered three-bladed shear for distortion free shearing with two (2) die spring loaded stripper pads to hold the strip during shearing for a straight cut.

• Automatic V.C.R. relay senses that the welding arc is correctly established before the welding carriage is allowed to travel.

• Fused disconnect is standard on all PSA control panels. Step-down transformer is also standard. Only one (1) electrical line is required.

• Quick change backup bars are provided. Only one screw at the front of the machine is required to remove each bar. Both L-R or R-L strip flows are handled easily with the automatic built-in gage bar.

Other designs with manual gauge bars require the exit strip to be sheared and laid on the floor, then the entry strip is sheared and clamped, then the exit strip is clamped. With this type of manual gage bar design, the process is both time consuming and awkward.
