What to do if nothing happens when depressing torch trigger switch on CIGWELD Welding System?
If the mains supply voltage is ON, but nothing happens when the torch trigger switch is depressed on your CIGWELD Welding System, the torch trigger switch leads may be disconnected. Reconnect them.
Why CIGWELD Transmig 250 Welding System has excessive spatter?
Excessive spatter can occur if the arc voltage is too high or too low. To fix this, lower the voltage by reducing the Voltage Control switches positions or turn the Wirespeed control knob clockwise if the voltage is too high. If the voltage is too low, raise the voltage by increasing the Voltage Control switches or turn the Wirespeed control knob anti-clockwise.
How to resolve undercut in CIGWELD Welding System?
If you're experiencing undercut, it could be due to several factors. If the welding arc voltage is too high, reduce it by adjusting the Voltage Control switches positions or turn the Wirespeed control knob clockwise. Also, ensure your torch angle is correct and adjust it if necessary. Finally, if there's excessive heat input, increase the torch travel speed or reduce welding current by reducing the Voltage Control switches positions and turn the Wirespeed control knob anti-clockwise.
What causes lack of penetration in CIGWELD Welding System and how to fix it?
Lack of penetration can be caused by a welding current that is too low. Increase welding current by increasing turn the Wirespeed control knob clockwise and increasing Voltage Control switch positions. It can also happen if the joint preparation is too narrow or the gap is too tight, so increase the joint angle or gap. Finally, the shielding gas may be incorrect, so change to a gas which gives higher penetration.
What causes lack of fusion in CIGWELD Transmig 250 Welding System?
Lack of fusion in your CIGWELD Welding System can be caused by voltage that is too low. Increase voltage by increasing the voltage selection switch position.
What to do if CIGWELD Transmig 250 Welding System has inconsistent wire feed?
If your CIGWELD Welding System is experiencing inconsistent wire feed, consider these potential causes and solutions: * If the wire spool brake is too tight, the feed roller driven by the motor in the cabinet will slip. * If the wire spool brake is too loose, the wire spool can unwind and tangle. * Worn or incorrect feed roller size: use a 'U' groove drive feed roller matched to the aluminum wire size you are welding. * Mis-alignment of inlet/outlet guides: wire will rub against the mis-aligned guides and reduces wire feedability. * Liner blocked with swarf: increased amounts of swarf is produced by the electrode wire passing through the feed roller when excessive pressure is applied to the pressure roller adjuster. * Incorrect or worn contact tip: the contact tip transfers th...
What causes lack of penetration in CIGWELD Welding System?
Lack of penetration in your CIGWELD Welding System can be caused by a welding current that is too low, a joint preparation that is too narrow or a gap that is too tight, or an incorrect shielding gas. Increase welding current by increasing wire feed speed and increasing the voltage selection switch position. Increase the joint angle or gap. Change to a gas which gives higher penetration.
Why is the weld shape irregular with my CIGWELD Transmig 250?
An irregular weld shape with your CIGWELD Welding System can stem from incorrect voltage and current settings (convex shape indicates voltage too low; concave shape indicates voltage too high), a wandering wire, incorrect shielding gas, or insufficient/excessive heat input. Adjust voltage and current using the voltage selection switch and wire speed control. Replace the contact tip if the wire is wandering. Check the shielding gas, and adjust the wire speed control or voltage selection switch to manage heat input.
What to do if CIGWELD Transmig 250 mains indicator light is not lit but welding arc can be established?
If the mains indicator light is not lit but a welding arc can be established, it is likely due to a burnt out indicator light. Have an Accredited CIGWELD Service Agent replace the indicator light.
What to do if CIGWELD Transmig 250 indicator light is ON but welding arc can not be established?
If the indicator light is on but a welding arc cannot be established, it might be because the Coarse Voltage Control switch is in the STANDBY position. Switch the Coarse Voltage Control switch to a welding setting.
