Tight connections should be maintained on welding cable terminals to eliminate what?

• A. Increased resistance
• B. Excessive spatter, poor bead quality, reduced weld gum
• C. Higher energy consumption
• D. Longer cooldown times

Answer: (B)

Tight welding cable connections create a solid, low-resistance path for the current. When a connection is loose, resistance climbs at the terminal, causing localized heating and an unstable arc. That instability tends to arc at the lug and throw molten metal, producing excessive spatter. It also hurts the consistency of heat input to the weld pool, so the bead forms unevenly and with poorer fusion. Keeping connections tight minimizes resistance and arcing, leading to cleaner welds with better bead quality and overall weld integrity.
