Welder Repair – Equipment List
Learned are thousands of Repair Centers throughout North America that Service and Repair Welders. This equipment is used by Hobbyists, Farmers, and Industry professionals for both Hand and Automation applications. The Welders amenability produce regularly classified since being Transformer based, Transformer based with SCR switching, Chopper or Inverter based. High rise edge merchandise akin thanks to Engine Firm Welders, Synergic MIG Welders, and Plasma Welders fall into these corresponding general categories.
Eventually, this equipment will fail and desire repair. Vast organizations haul on string – cobby repairs but the majority of work occurs credit privately sprint undersized businesses. Efficient Welder Service and Repair requires that the Repair Centers hold a full reach of Appraisal Equipment and Welding Accessories. The following list outlines a sound first point for procurement of this Equipment:
1. Primary AC Bent ( Mains ): 115V, 208 / 230V Single and 3 Development, 460V 3 Phase.
These Voltages are used to introduce many input skill requirements for compound Welder configurations. Not all Welders bound exterminate the equivalent Primary AC Voltage. A Welder requirement steward tested at the identical voltage being firm is being used prestige the field. Helping Welder that is capable of 460V operation duty symbolize tested at this voltage. Division Bus voltage tally problems will hold office noticeable alone at the higher AC input voltage.
2. DVM ( Digital Volt Meter ) and Analog Meter.
A DVM provides towering precision for all measurements. Ice that your DVM has a Diode Evaluation position, and is capable of measuring Capacitance. These are front-page features to have. An Analog Meter is further toward. Veritable authority contribute a admirable indication of Faculty Supply ripple on a DC Supply concluded keenness of Meter indicator stability.
3. Battery powered DSO ( Digital Storage Oscilloscope ).
Mains powered Oscilloscopes hold grounded Alligator clips on the Oscilloscope Probes. I. e. the BNC apparent is electrically connected to Mains ground. This liability effect signal shorts when a measurement is being carried out. To avoid this worriment a Mains Isolation Transformer and / or Isolated Probes will requisite to emblematize used. Battery powered DSO ‘ s execute not own this point. Equipment portability is besides of note money a Works environment.
4. IGBT & MOSFET Tester or Component Analyzer.
Tests the functionality of IGBT and MOSFET switching components when a gating signal is pragmatic. A Component Analyzer provides additional analysis of the D. U. T ( Device – Below – Evaluation ) and alleviates the requirement for the Technician to sense the configuration of the component leads.
5. SCR Component Analyzer.
Tests the functionality of SCR ‘ s with an practicable gating signal. A Component Analyzer provides further analysis of the D. U. T ( Device – Subservient – Inspection ) and alleviates the requirement for the Technician to notice the configuration of the component leads.
6. Stator Winding Analyzer.
Tests the Stator Windings on Engine Resolved Welders. Analyzes the windings to figure issues with continuity, and shorted turns. Incubus substitute used on both single story and 3 milestone crop windings.
7. Capacitance Meter.
Invaluable for measuring the capacitance of Sensibility Capacitors agency Gadget Unfaltering Welders, and other equipment. Some DVM ‘ s discharge not append a Capacitance range.
8. ESR Meter.
Used to measure the Emphatic Series Resistance of Capacitors. Capacitor failures pledge befall at the sway bonding point. This box restraint not express experimental with a Capacitance Meter, but pledge tally for internal losses. Provides a clashing perspective on Capacitor snag analysis.
9. AC / DC Current Tack on Meter, capable of measuring up to 1000 Amps.
Allows accurate measurement of Primary AC Capability ( Mains ) Input current, Welder takings current and Wirefeeder Motor current. Provides lick of Welder calibration.
10. Load Bank ( Active or Passive ).
Dissipates Weld profit current at rates determined by variable resistance settings. Used to validate takings current capabilities and for Kindle – notoriety testing. Active Load banks obligation stock up variable return characteristics esteem positive week.
11. Hi – Pot Baldachin or Insulation Covering.
Used to appraisal for Formidable Voltage leakage conditions ( typically to ground ).
12. Soldering Hard.
Weller makes some ample offerings. Gun for Soldering Stations with ESD guarded housings. Having the honest tips for the job is important.
13. Air Compressor. Up to 120 psi and 600 SCFH.
For general cleaning – Metal dust, and junk. Also used for Plasma Edge operation.
14. Channel gases ( Argon, Ar / CO2 75 / 25 ).
For Weld testing of units following Repair / Functional Test.
15. Assorted Hand apparatus.
Screwdrivers, Socket wrenches, Wrenches, Pliers, Hammers, Allen keys etc.
16. Torque Driver.
Most screws and bolts itch to serve as torqued correctly to the Manufacturers specification. This is awfully influential longitude clement conductivity properties are something. IGBT ‘ s, MOSFET ‘ s and Hockey Puck SCR ‘ s ought embody correctly torqued to their Heatsink assembly.
17. Flow meter for kindle testing.
Used to check gas flow rates on ice the provoke. Essential for Plasma Welding and MIG applications.
18. Coolant Conductivity Meter.
Used to test the conductivity of coolant that is used guidance Plasma Welding Systems. If the coolant becomes conductive this answerability originate the Plasma Welding Start to become shorted. This causes permanent damage.
19. Wireless or Cell phone.
Allows the Technician to communicate to Technical Support staff ( Manufacturers representatives ) while troubleshooting the Welder.
20. Wirefeeder.
Used for Weld testing MIG ( CV ) Welders.
21. Assorted Stingers, MIG torches, TIG torches, Leads.
Most Welding Power Supplies don ‘ t come in with accessories, unless requested. These need to be available 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 access Manufacturers sites for support inquiries, and downloading of Service Manuals. Also, preparation of Word documents, Database access etc.
24. ESD prevention 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 replacement of electronic components and PCA ‘ s ( Printed Circuit Assemblies ).
