Mig Welder Price List

The mig welder uses the high-temperature arc generated by the positive and negative poles in an instantaneous short-circuit to melt the solder and the material to be welded on the electrode to combine the objects to be contacted. Its structure is very simple, it is a high-power transformer. ATO provides Arc mig welder, AC and DC welding machine, DC welding machine, input voltage 110V, 220V, 230V and 240V are optional.

Mig Welder Troubleshooting

1. The mig welder has no welding current output.
Fault reason: There is no voltage input at the input end of the welder, the internal wiring is disconnected or broken, the internal coil is burnt out.
Treatment method: Check the switch, wire, fuse and connection part from the distribution box to the input end of the welder. Check that the wiring of the internal switch and coil of the welder is intact. Check if the internal components of the welder are burnt out (it is obvious that the burnt marks are usually burnt, and a special smell will be smelled when burned). If it burns out, it should be replaced.

2. The mig welder has a small current or difficulty in arc ignition.
The cause of the fault: The grid voltage is too low, the cross-sectional area of the power input line is too small (high resistance, high voltage loss), the welding cable is too long or the cross-sectional area is too small, there is paint and other dirt on the workpiece, and the output cable of the welder is in poor contact with the workpiece. The current regulator is partially loose.
Treatment method: After the grid voltage is restored to the rated value, use the power cord with sufficient cross-sectional area according to the rated input current of the welder, increase the cross-sectional area of the welding cable or reduce the length of the welding cable, generally no more than 15m, remove the weld The dirt makes the output cable in good contact with the workpiece and the loose current part of the fixed current regulator.

3. The mig welder is overheated, smoked or anxious.
The cause of the failure: The welding machine is overloaded, the grid voltage is too high, the wiring is wrong, the common reason is that for the mig welder with 220V and 380V voltage available, the 380V voltage is connected to the 220V input terminal.
Treatment method: avoid overload use and reduce welding current. When using 220V single-phase power supply, it must be connected to the 220V input terminal of the welding machine. When using 380V two-phase power supply, it must be connected to the 380V input terminal of the welding machine.

4. The stick welder noise is too large.
Cause of failure: The housing or chassis fastening screws are loose.
Solution: check the fastening screws to eliminate looseness.

5. Wire contact is overheated.
Cause of the fault: The screw at the wiring is loose, and the contact resistance at the wiring is too large.
Treatment: tighten the terminal screws, remove the oxide layer, and reduce the contact resistance.

6. The mig welder shell is charged.
The cause of the fault: The power cable or the welding cable is touched by the welder casing. The insulation of the welding cable is damaged and the workpiece is touched. There is no grounding protection (or zero-connection protection) or the grounding wire is connected to the power line of the power supply.
Treatment method: check the wiring, eliminate the phenomenon of the welding part of the welding machine, check the welding cable, wrap the damaged part with the insulation tape, check the grounding wire, ensure the grounding is reliable, and the connection is correct. The electric welding operator must check the reliability of the grounding before operation. Only the grounding is reliable to ensure the safety of the operator.

7. The cooling fan does not turn (some welders do not have a cooling fan).
Cause of the fault: The fan is out of power. The common cause is that the wire is disconnected, the wire is broken or the contact is poor, the blade is stuck, and the fan motor is damaged.
Treatment method: Check the fan wiring, remove the fault, gently move the fan blade to check whether the rotation is flexible; replace the motor or the entire fan.
