Hand Held Electronic Force Gauge
An ergonomically designed hand held force gauge.
ADVANTAGES
User comfort "'Ergonomically" designed - for ease of use
One piece unit
Very high accuracy
Swivel head allows access to difficult to reach positions
As with all welding procedures, it is important to eliminate as many variables as possible in order to achieve optimum welding consistently over long periods.
Electrode force is one of the critical parameters in obtaining repeatable, reliable resistance spot welds.
Force can vary because of variable factory air pressure, water in the air lines causing air cylinders to deteriorate and loss of air pressure due to worn seals.
This self contained instrument uses a cell with a force sensor to provide accurate digital read out for auditing weld electrode forces.
Accuracy of this instrument is better than 0.2% and can be switched to read 0-2000 kg, 0-20.00 kN or 0-4400lbs.
In cases of difficult access the head of the swivel head gauge can be swiveled at least ±72º up or down and rotates at least ±90º. Once the desired position is reached it can be fixed by a simple hand tightened knob. A 90 mm long handle is provided for optional use with 2 mountain positions either in-line or at 90º.
A support wrist strap is attached to the gauge so that in the event that it is forced out of the operators hand by misaligned electrodes, it need not fall to the floor and be damaged. |

Faults in welding tongs or incorrect process parameters in welding can result in production line waste or defective parts. Checking the electrode force periodically permits spark malfunctions to be detected at an early stage so that repairs can be carried out in good time.
The new Type 9833A test sensor allows precise and reliable measurements to be carried out with minimal electrode gaps. The built-in charge amplifier simplifies the task of mounting and helps to ensure the reliability required by the automobile industry.

| The MM-601A is an electrode force measuring device for resistance welding machines. By changing the load sell sensor, it is capable of measuring from 0.20 kg to 950 kg (0.44 to 2111 lbs) of weld pressure. |

The quality of a spot weld depends on the force applied by the electrodes together with the value of the welding current. For control programs, measuring the force applied by the electrodes is extremely important for maintaining constant production conditions. The Welding Tester instrument is designed for measuring the closing force on welding heads, which can be used either for setting up or for periodical maintenance. The tips are exchangeable for measuring the force applied by different forms of electrodes; the lowest closing dimension is 3 mm.
Different models are available for measuring 0–5000N up to 0-20000N. The new tool has all the ruggedness, quality and accuracy of the other tools in the CENTOR family, specially designed for taking “nomad” measurements in production shops.

Satellite Paste Applicators are designed to complement an existing heat source, such as furnace or induction. These freestanding units apply single, multiple, or "ring shape" paste deposits onto assemblies. Cycling is automatic and error-free with an operator removing the pasted part and loading it into the adjoining heat source.
Applicator guns can also be mounted to a robot to apply a detailed combination of paste dots and stripes to a particular part. After the pasting cycle, the part is joined to its companion members and fixtured to the subsequent heating and cooling sequence.
Dual station system utilizes rotating mandrel technique to apply 360° stripe of Fusion Paste onto part joint area. |

Whatever your application, whatever your fuel gas, there's a Smith SlicerTM tip to provide fast, economical and quality cutting. Soft seats are not prone to damage like metal-to-metal seats, providing consistent seating and much longer life than metal to metal seats.
FEATURE BENEFITS
1. In-Tip Mix Provides Added Resistance to Flashback
Each tip is a precision engineered mixer for combining preheat oxygen and fuel gas to attain maximum efficiency.
2. Slip-In Design Saves Time and Money
Quick, easy tip change encourages use of right tip for the job.
3. Hand Tighten Tips - No Wrench Needed!
After the first tightening with a wrench, all that's needed to seat the tip snugly is hand-tightening. No need to search for a wrench to change tips; threads on tip nut won't be stripped by over-tightening.
4. Soft Graf-Tite® Flexible Seats End Reseating Repairs
Compressible soft seats are practically indestructible and they withstand very high temperatures, resulting in longer tip life.
5. Fully Swaged Tip Minimizes Gas Turbulence
Mirror smooth gas passages deliver stable gas flows for high heat transfer, fast starts and clean cuts, also, minimizes slag build-up, and reduces clean-up time.
6. Concave Shaped Tip End
Reduces backfire and resists flameout when making accidental contact with base metal during cutting operations.
7. Removable High Pressure Seat
Allows cleaning from back of tip. |
