Inspect Welding Leads Before the Arc

Know the hazard

Team: Welders. Topic: Welding Safety.

A welding lead is part of an electrical circuit, not just a rugged extension of the machine. Crushed insulation, exposed conductors, damaged holders, and poor connections can create shock and heat hazards. Repeatedly stepping over a damaged cable does not make its condition acceptable. The pre-use check should happen before the lead is laid through the work area.

Use the controls

Inspect accessible cables and connections under the approved deenergized procedure. Remove damaged equipment from service and have qualified personnel make permitted repairs or replacements. Do not improvise a splice or conceal a defect with whatever tape is nearby. Route leads away from vehicle tires, sharp steel, hot slag, and standing water. Avoid wrapping them around the body or carrying current through unintended objects. Keep the work area arranged so people can move without pulling the connections loose.

Work within the safe plan

Know the normal shutdown and isolation method before repositioning equipment or handling a fault. Never open the power source or touch internal components unless qualified and authorized. If a cable heats unexpectedly, a connection arcs, or the machine behaves abnormally, stop and report it rather than increasing settings to compensate. Include the lead route in housekeeping checks as fabrication progresses, because a cable protected at the start may be crushed under the next assembly.

Discuss with the crew

A forklift drives over an electrode cable and leaves its insulation flattened and split.

Question: Can welding continue if the machine still works?
Answer guidance: No. Stop and remove the damaged lead from service for qualified evaluation.

Question: Why check routing again during fabrication?
Answer guidance: Moving parts, traffic, and hot work can damage a route that was initially protected.

Prepare, act, and follow up

Leader preparation: Use an isolated sample lead or photographs of defects.

Put it into practice: Inspect one isolated lead and identify its protection at crossings and sharp edges. Have the crew identify who will receive a rejected cable and who can release its replacement.

Supervisor follow-up: Record rejected leads and verify replacements before restarting.
