Why won't it weld?

If your Lincoln Ranger 250 gas welder is running but not striking an arc, there could be a few potential issues causing this problem. Here are some steps you can take to troubleshoot the issue:
1. Check the welding leads and connections: Ensure that the welding leads are securely connected to both the welder and the workpiece. Make sure the connections are tight and free from corrosion or damage.
2. Check the electrode/ground clamp connections: Inspect the electrode holder and ground clamp connections for any loose or damaged parts. Ensure that the electrode holder is securely gripping the welding electrode.
3. Check the welding electrode: Examine the welding electrode for any signs of damage or wear. Replace the electrode if it appears worn out, as it may not strike an arc effectively.
4. Check the power source: Verify that the power source to the welder is adequate. Ensure that the welder is receiving the correct voltage and that the power source is providing sufficient power.
5. Check the welding settings: Review the welding settings on the welder to ensure they are appropriate for the type and thickness of the metal you are working on. Adjust the settings if necessary.
6. Check the welding environment: Make sure you are operating in a clean and well-ventilated area. Remove any contaminants or debris from the workpiece and ensure good contact between the workpiece and the ground clamp.
7. Check the welder's internal components: If the above steps do not resolve the issue, it may be necessary to inspect the internal components of the welder. This requires expertise and should be performed by a qualified technician. Contact a professional repair service or the manufacturer for assistance.
Remember, safety is crucial when working with welding equipment. Always follow proper safety precautions and wear appropriate protective gear, such as welding gloves and a welding helmet, to protect yourself from potential hazards.

Magnetic reed switch near output is probably bad. Look for coil behind front panel, there is a small glass tube inside, with 2 small wires.

Why does my miller bobcat welder generator not stay at an idle when swithed to low idle, insted it goes back and ... Won't strike an arc,fuses ok brushes and slip.

Sounds like a power or ground issue ie. not enough power or a poor ground circuit

Does the electrode stick to the metal? In which case your problem is with the elctrode or your method of striking the arc.

try striking the rod like a match. keep a good arc, not too long or short. try around 90 amps.

check your input power connections on the primary side of the welders transformer, then if its an infinite control welder check that control,otherwise if it's a plug- in selectable amperage check these connections,it sounds like the infinite control is getting dirty and not passing all the current it shows on the control, also double your O.C.V. on the secondary and see if its with-in welder specs

Need code number to be exact, but sounds like the wiring to the current transformer is incorrect.

i took an old trickle battery charger,6 volts and energize the armmiture,all so called polarizing,google it ,shows how also
