*Tongs-
*Electrode Tips – The copper ends of the tongs that make contact with the workpiece to deliver welding current.
*Arms / Handles – The insulated portions you hold; provide leverage to open/close the tongs.
*Jaws – The part of the tongs where the electrode tips are mounted; may pivot to adjust pressure.
*Adjustment Knob / Screw – Used to set electrode pressure for consistent welds.
*Cable / Conductor – Heavy cable connecting the tongs to the welder to carry welding current.
*Spring Mechanism – Internal spring that helps return the tongs to the open position when released.
*Insulation / Grip – Protective covering to prevent electric shock and allow safe handling.

==Troubleshooting==
==Troubleshooting==
*No weld or weak weld:
**Check electrode tips for wear, dirt, or oxidation; clean or replace as needed.
**Verify proper electrode pressure; adjust using the adjustment knob/screw.
**Ensure cables are securely connected and not damaged.
*Sparks at handles / arcing:
**Inspect insulation on handles and tongs; replace if cracked or damaged.
**Confirm all connections are tight and corrosion-free.
*Tongs won’t open/close smoothly:
**Check spring mechanism for damage or debris; clean and lubricate lightly if needed.
**Ensure pivot points are not seized or misaligned.
*Overheating tongs:
**Reduce duty cycle; allow tongs to cool between welds.
**Check for proper current settings and electrode contact.
*Uneven welds:
**Inspect electrode tips for uneven wear; dress or replace as needed.
**Confirm correct alignment of jaws and consistent pressure.
