MIG Wire Feeds but No Arc? Check the Work Clamp and Return Path
If a MIG welder feeds wire but will not start a stable arc, inspect the work clamp, contact surface, cable, connectors, and polarity before replacing larger components.

Plasma Arc Starting Then Stopping Troubleshooting: Pilot Arc Dropout, Transfer Loss, Air, Work Clamp, and Consumable Checks
If a plasma arc starts and then stops, fires briefly then drops out, starts the pilot arc but will not transfer, or cuts for a second and shuts off, troubleshoot air supply,…

Stick Electrode Sticking During Arc Start: Amperage, Arc Length, Rod Condition, Polarity, Ground, and Hot Start Checks
Stick electrode sticking during arc start usually means the arc is not getting hot and stable fast enough to keep the rod from fusing to the work. The common causes are low…

Stick Welding Arc Blow Causes and Fixes: Magnetic Arc Deflection, Ground Clamp Placement, AC/DC Settings, and Weld Sequence
Stick welding arc blow happens when the arc is pulled, pushed, or deflected away from the joint instead of staying under the electrode. The usual symptoms are a wandering arc, undercut on…

MIG Contact Tip Overheating Causes: Wire Drag, Short Stickout, Loose Tip, Duty Cycle, Ground, and Gun Setup
MIG contact tip overheating shows up as blue/purple discoloration, repeated burnback, wire sticking inside the tip, unstable arc, spatter welded to the tip face, loose consumables, or tips that fail after only…

Lincoln Power MIG Poor Arc Stability Troubleshooting: Wire Feed, Contact Tip, Liner, Gas, Ground, and Settings
Lincoln Power MIG poor arc stability usually comes from inconsistent wire delivery, poor electrical return, wrong setup, or shielding gas problems before it comes from a failed control board. Common symptoms include…

Plasma Cutter Pilot Arc Failure Troubleshooting: No Start, Weak Spark, Arc Dropout, and Torch Consumable Checks
Plasma cutter pilot arc failure usually comes from worn consumables, poor air supply, incorrect torch assembly, a bad work lead path, torch safety-circuit problems, or internal pilot-arc circuit failure. If the torch…

MIG Ground Clamp Connection Problems: Arc Sputter, Heat, Poor Starts, and Weak Current Return
A bad MIG ground clamp connection causes arc instability, poor starts, extra spatter, weak penetration, burnback, and random sputtering even when voltage and wire speed look correct. The work clamp is not…

Ground Clamp Replacement Guide: FGC200 200 Amp Clamp for Welding Setups
Why this matters A weak ground clamp causes arc instability, poor starts, and wasted time. If the clamp is loose, corroded, or undersized for the job, the machine cannot deliver a consistent…
