Welders Power Tools: Welder repair

There are thousands of heal Centers throughout North America that assistance and heal Welders. This equipment is used by Hobbyists, Farmers, and commerce professionals for both Hand and Automation applications. The Welders can be commonly classified as being Transformer based, Transformer based with Scr switching, Chopper or Inverter based. High end products such as motor Driven Welders, Synergic Mig Welders, and Plasma Welders fall into these same normal categories.

Eventually, this equipment will fail and need repair. Large organizations take on in-house repairs but the majority of work occurs in conspiratorially run small businesses. Efficient Welder assistance and heal requires that the heal Centers have a full range of Test equipment and Welding Accessories. The following list outlines a good beginning point for procurement of this Equipment:

Ramsond CT 520DY 3-in-1 Multifunction Digital Inverter Plasma Cutter + TIG Welder + ARC (MMA) Welder, Dual Voltage 110/220V Dual Frequency 50/60Hz Overview

Ramsond introduces the 4th generation of its CT520DY. CT520DY is a 3-in-1 multifunction cutting and welding machine. It is a 50 Amp plasma cutter, a 200 Amp DC (Direct Current) TIG welder and a 200 Amp ARC/MMA stick welder. It is dual voltage 110V/220V and dual frequency 50/60 Hz. It is equipped with DIGITAL AMP DISPLAY, INTEGRATED PRESSURE GAUGE, FOOT PEDAL FUNCTION and FOLDABLE INSULATED HANDLE. It uses the most reliable high frequency V-MOSFETs by TOSHIBA along with PWM (Pulse Width Modulation Processor) which help deliver a constant, concentrated and precise current to the cutting/welding surface. Regardless of your training, you can achieve smooth, clean and uniform cuts (1 inch) and weld a wide range of surfaces and material (e.g. stainless steel, carbon steel, alloy steel, copper, brass and other conductive material) with minimal heat input and without distortion of metal. CT520DY is easy to use by the do-it-yourself user, while fully accommodating of the demands of professional operators. It has five controls; the ON/OFF switch, Amperage Control Knob, the Post Flow Knob, Function Selector and the foot pedal ON/OFF switch. It has an integrated air pressure gauge in the front panel of the unit, as well as a large digital display that conveniently displays the current (Amps) setting of the unit. Note: This is a DC (Direct Current) TIG Machine. For aluminum welding AC (Alternating Current) is recommended. Each Ramsond CT520DY comes fully equipped with all accessories: TIG Torch, Plasma Torch, ARC/MMA Electrode Clamp, Air Regulator/Filter, Argon Flow Meter, Set of Consumables for the plasma and TIG torches, and Ground Clamp. Plug is not included. It comes with a 1 year Limited Warranty (Parts and Labor). The consumables are readily available both through Ramsond and third party sellers and are reasonably priced.

These Voltages are used to encompass various input power requirements for complicated Welder configurations. Not all Welders run off the same Primary 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 execution 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 foremost features to have. An Analog Meter is also useful. It can supply a good indication of Power supply ripple on a Dc supply 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 connected to Mains ground. This can cause signal shorts when a estimation 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 foremost 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 supplementary 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 supplementary 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 determine issues with continuity, and shorted turns. Can be used on both particular phase and 3 phase output 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 part the Efficient 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 list for internal losses. Provides a separate perspective on Capacitor fault analysis.

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

Allows definite estimation of Primary Ac Power (Mains) Input current, Welder output current and Wirefeeder Motor current. Provides confirmation of Welder calibration.

10. Load Bank (Active or Passive).

Dissipates Weld output current at rates carefully by adjustable resistance settings. Used to validate output current capabilities and for Burn-in testing. Active Load banks can supply changeable output 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 normal 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. various 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 highly foremost 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 through the torch. foremost 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 come to be shorted. This causes permanent damage.

19. Wireless or Cell phone.

Allows the Technician to chronicle to Technical support staff (Manufacturers representatives) while troubleshooting the Welder.

20. Wirefeeder.

Used for Weld testing Mig (Cv) Welders.

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

Most Welding Power Supplies don't come in with accessories, unless requested. These need to be ready in separate 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 support inquiries, and downloading of assistance Manuals. Also, establishment of Word documents, Database entrance etc.

24. Esd arresting materials and equipment.

Suitable lengths and quantities of Static Dissipative Matting, Wrist Straps, Foot Straps, Cords, Bonding Points, etc for setting up an Epa (Esd Protected Area). This designated area will be used for exchange of electronic components and Pca's (Printed Circuit Assemblies).
