Common Troubleshooting of H Beam Assembly Weld Straighten Integral Machine

1. Equipment Outline:

H Beam Assembly Weld Straighten Integral machine is used for manufacturing light-duty H beam (Welding toe size is 6~12mm under single pass welding), integrating function of H beam assembly, welding and straightening.


H Beam Assembly Weld Straighten Integral machine is equipment of high efficiency, energy saving and high return on investment. Data analysis as below:

1) Investment on one set of H Beam Assembly Weld Straighten Integral machine is 70% that of total investment of Assembly machine, Welding machine and Straightening machine;

2) Land occupation of one set of H Beam Assembly Weld Straighten Integral machine is one third that of Assembly machine, Welding machine and Straightening machine;

3) Electricity consumption of one set of H Beam Assembly Weld Straighten Integral machine is 50% that of Assembly machine, Welding machine and Straightening machine;

4) One set of H Beam Assembly Weld Straighten Integral machine can remove H Beam hoisting and transporting equipment among Assembly machine, Welding machine and Straightening machine;

5) Operation of one set of H Beam Assembly Weld Straighten Integral machine only need 2 operators, comparatively, operation of Assembly machine, Welding machine and Straightening machine and transporting equipment need 6 operators

6) With H Beam Assembly Weld Straighten Integral machine, H beam assembly, welding and straightening can be made with one pass one time operation, lifting efficiency 60%~70% compared with using 3 machines.



H Beam Assembly Weld Straighten Integral machine is also high-tech equipment in welding industry. Ever since Wuxi JACK took the lead in launching the mature product in 2009, accomplishing upgrading the product from years of concept design to practical application, Wuxi JACK keeps design of the equipment in continuous improvement status: Machine design is kept on continuous optimizing based on customer feedback and summary.


1. Common Troubleshooting of the Equipment:

To make the H Beam Assembly Weld Straighten Integral machine fully play to its advantage, smooth operation of the machine without malfunction is very important. Same as all other products produced by Wuxi JACK, quality always takes one of top priorities in the design and manufacture of the machine, from incoming material purchase, manufacture to after-sale service, making sure the machine always has best quality. Meanwhile, due to some unforeseen or unexpected factors, sometimes there may certain defects crop up. JACK provide one year guarantee from the date product acceptance, and most favorable service price at expiry of the guarantee. Also, to remove trouble in the earliest time, and restore the H Beam Assembly Weld Straighten Integral machine back to normal operation, it is vital important to command way of troubleshooting


Below is list of common troubleshooting for the H Beam Assembly Weld Straighten Integral machine summarized by Wuxi JACK on the basis of years of experience:


I. Malfunction: Oil Pump No Work:

1) Possible Cause: No power; Solution: Check breaker and or cable and remove defect;

2) Possible Cause: No work of contactor of oil pump motor; Solution: Inspect control circuit, its pushbutton and coil;

3) Possible Cause: Oil circuit blocked; Solution: Clean oil circuit and replace oil


II. Malfunction: No work of main power motor or its alarm light illuminates:

1) Possible Cause: Inverter alarms; Solution: Inspect and remove trouble based on inverter manual;

2) Possible Cause: Thermal relay trips; Solution: Find trip reason and remove trouble;


III. Malfunction: No wire feeding 

1) Possible Cause: Wire spool blocked; Solution: Remove mechanical trouble;

2) Possible Cause: Electric circuit of welding machine defect; Solution: Remove trouble based on manual of welding machine


IV. Malfunction: No work of flux recovery unit, or incomplete recovery process

1) Possible Cause: Leakage in suction pipeline; Solution: Overhaul suction pipeline;

2) Possible Cause: Position of suction pipeline nozzle is too high; Solution: Adjust position of suction pipeline nozzle;

3) Possible Cause: Defect recovery unit; Solution: Overhaul recovery unit;

4) Possible Cause: Sieve blocked; Solution: Clean the sieve;

5) Possible Cause: Contactor or pushbutton fail; Solution: Repair or replace the electric components


V. Malfunction: Speed of main roller motor can not be adjusted, or no digital display

Possible Cause: Speed knob fails; Solution: Replace speed knob;

Possible Cause: 5V Power fails; Solution: Replace the 5V Power;

Possible Cause: Transformer fails; Solution: Replace the transformer;

Possible Cause: Digital play fails; Solution: Replace the digital display


VI. Malfunction: Welding machine can not be started

Possible Cause: Incorrect welding mode; Solution: Set up correct welding mode;

Possible Cause: Control cable breaks; Solution: Replace control cable;

Possible Cause: Control circuit fails; Solution: Repair control circuit


2. Postscript:

Last but not least, keep electric diagram, foundation drawing and hydraulic diagram of H Beam Assembly Weld Straighten Integral machine correctly.
