These Voltages are used to encompass discrete input power requirements for complicated Welder configurations. Not all Welders run off the same Traditional Ac Voltage. A Welder must be tested at the same voltage as it is being used in the field. Any Welder that is capable of 460V performance must be tested at this voltage. Any Bus voltage balance problems will be noticeable only at the higher Ac input voltage.

2. Dvm (Digital Volt Meter) and Analog Meter.

A Dvm provides great precision for all measurements. Ensure that your Dvm has a Diode Test position, and is capable of measuring Capacitance. These are important features to have. An Analog Meter is also useful. It can furnish a good indication of Power furnish ripple on a Dc furnish straight through judgment of Meter needle stability.

3. Battery powered Dso (Digital storage Oscilloscope).

Mains powered Oscilloscopes have grounded Alligator clips on the Oscilloscope Probes. I.e. The Bnc outer is electrically linked to Mains ground. This can cause signal shorts when a determination is being carried out. To avoid this question a Mains Isolation Transformer and/or Isolated Probes will need to be used. Battery powered Dso's do not have this issue. equipment portability is also important in a Workshop environment.

4. Igbt & Mosfet Tester or Component Analyzer.

Tests the functionality of Igbt and Mosfet switching components when a gating signal is applied. A Component Analyzer provides added diagnosis of the D.U.T (Device-Under-Test) and alleviates the requirement for the Technician to know the configuration of the component leads.

5. Scr Component Analyzer.

Tests the functionality of Scr's with an applied gating signal. A Component Analyzer provides added diagnosis of the D.U.T (Device-Under-Test) and alleviates the requirement for the Technician to know the configuration of the component leads.

6. Stator Winding Analyzer.

Tests the Stator Windings on motor Driven Welders. Analyzes the windings to resolve issues with continuity, and shorted turns. Can be used on both single phase and 3 phase production windings.

7. Capacitance Meter.

Invaluable for measuring the capacitance of Excitation Capacitors in motor Driven Welders, and other equipment. Some Dvm's do not contain a Capacitance range.

8. Esr Meter.

Used to quantum the Sufficient Series Resistance of Capacitors. Capacitor failures can occur at the lead bonding point. This question can not be seen with a Capacitance Meter, but can inventory for internal losses. Provides a different perspective on Capacitor fault analysis.

9. Ac / Dc Current Clamp Meter, capable of measuring up to 1000 Amps.

Allows correct determination of Traditional Ac Power (Mains) Input current, Welder production current and Wirefeeder Motor current. Provides confirmation of Welder calibration.

10. Load Bank (Active or Passive).

Dissipates Weld production current at rates determined by adjustable resistance settings. Used to validate production current capabilities and for Burn-in testing. Active Load banks can furnish changeable production characteristics in real time.

11. Hi-Pot Tester or Insulation Tester.

Used to test for High Voltage leakage conditions (typically to ground).

12. Soldering Iron.

Weller makes some great offerings. Look for Soldering Stations with Esd safe housings. Having the right tips for the job is important.

13. Air Compressor. Up to 120 psi and 600 Scfh.

For general cleaning- Metal dust, and debris. Also used for Plasma Cutter operation.

14. Cylinder gases (Argon, Ar/Co2 75/25).

For Weld testing of units after Repair/Functional Test.

15. discrete Hand tools.

Screwdrivers, Socket wrenches, Wrenches, Pliers, Hammers, Allen keys etc.

16. Torque Driver.

Most screws and bolts need to be torqued correctly to the Manufacturers specification. This is very important where thermal conductivity properties are important. Igbt's, Mosfet's and Hockey Puck Scr's must be correctly torqued to their Heatsink assembly.

17. Flow meter for torch testing.

Used to check gas flow rates straight through the torch. important for Plasma Welding and Mig applications.

18. Coolant Conductivity Meter.

Used to test the conductivity of coolant that is used in Plasma Welding Systems. If the coolant becomes conductive this can cause the Plasma Welding Torch to become shorted. This causes permanent damage.

19. Wireless or Cell phone.

Allows the Technician to tell to Technical keep staff (Manufacturers representatives) while troubleshooting the Welder.

20. Wirefeeder.

Used for Weld testing Mig (Cv) Welders.

21. discrete Stingers, Mig torches, Tig torches, Leads.

Most Welding Power Supplies don't come in with accessories, unless requested. These need to be ready in different configurations for Weld testing the product.

22. Loading Dock with Fork Lift or Hoist.

Used to move heavy equipment in and out of the workshop.

23. Computer (Desk Top or Laptop) with Internet access.

Used to entrance Manufacturers sites for keep inquiries, and downloading of service Manuals. Also, making ready of Word documents, Database entrance etc.

24. Esd prevention materials and equipment.

Welding Machines

In market context, welding refers to a fabrication process that joins materials such as metals and thermoplastics, by causing coalescence. This is typically done by softening the work pieces and adding a filler material, which is often a welding rod, to form a pool of molten material that cools to become a strong joint. Various processes and power sources are used for welding, such as gas flame, electric arc, laser, electric beam, friction, and ultra sound.

Welding machines can be broadly classified into different categories depending on the type of welding processes and tool used during the process. Some welding machines use transformers for converting high voltage, low current electricity into high current low voltage, often in the middle of 17 to 45 volts and 190 to 590 amperes. These types of welding machines are the least costly and allow welders to settle on the output current by whether inviting the core of the transformer in and out of the magnetic field or by allowing the welder to settle on from a set of taps on the transformer.

Arc Welding Equipment Power Tools

Some welding machines use an internal combustion machine or an electric motor to drive the alternator or generator present in these machines. The process used is similar to transformer based welding machines as power is first converted into mechanical and back to electrical power to achieve the step-down affect.

Inverter based welding machines use high-power semiconductors such as the Igbt for construction a switching power provide capable of handling high loads of arc welding. These machines convert utility electricity into high voltage and store it in a capacitor bank. The stored power is then transferred to a secondary transformer for producing the desired welding current.

Welding machines have simplified different types of machining jobs undertaken in small and large manufacturing companies. Self-operating welding machines are also in use and have helped in expanding the effectiveness of welding processes.

Introduction to Plasma Cutters

Plasma cutters can cut steel and other metals of distinct thicknesses using a plasma torch. Plasma can also be used for plasma arc welding and other applications.

Plasma cutters are ready in assorted shapes and sizes. All consumables plasma cutters function on the same principle and are constructed nearby approximately the same design. Plasma cutters send pressurized gas, such as nitrogen, argon, or oxygen through a small channel. In the center of this channel, you'll find a negatively charged electrode.

Arc Welding Equipment Power Tools

Plasma cutters can cut distinct shapes in metals properly. It is a very easy and economic technique. With the help of these cutters, the cutting work can be done accurately, in full speed and cut any type of metal in any shape. Due to low level skill, plasma cutters are threat to approved metalworking tools. Plasma causes the vigor to break apart the gas molecules and the atoms begin to split. Commonly atoms have protons and neutrons in the nucleus, surrounded with electrons. But in case of plasma cutters, electrons isolate from the nucleus. Once the vigor of heat releases the electrons from the atom, the electrons begin to move nearby quickly. If you consideration most of the electrons are negatively charged and leave behind admittedly charged nuclei, known as ions. Electrons crash with other electrons and ions, which releases vast amount of energy, creating plasma and expected cutting power.

Plasma cutting machines are widely used in auto shops as well as by car manufacturers to customize and generate chassis and frames. Even building fellowships use plasma cutters in large-scale projects to cut and fabricate huge beams or metal-sheet goods. Locksmiths use plasma cutting machines to bore into safes and vaults when customers have been locked out.

One major benefit of plasma cutting is that the surface of the metal surface of the cutting area remains relatively cool; this prevents the warping and paint damage that can occur with other flame cutters. A thin heat affected zone also allows the use of templates for exact curved line cutting. Plasma cutters do well as gougers and can pierce metal fast and accurately.

Plasma cutting machines are also used in Cnc (computer numerically controlled) machinery. The idea behind Cnc tables is to allow a computer to control the torch head development clean sharp cuts. Nowadays, Cnc plasma equipment can cut thick material, which provides opening for complex welding seams on Cnc welding equipment that is not potential otherwise. For cutting thinner material, plasma cutter is substituted by laser cutting, due to classic hole-cutting abilities. Cnc plasma cutter are also used in Hvac industry. In the present scenario, there is more development in Cnc plasma cutting Machinery. In the past, cutting motor was horizontal in shape, but due to revision in technology, vertical Cnc plasma cutting machines are available.
