Proper Gun Handling
Most feeding problems are caused by improper han-
dling of the gun cable or electrodes.
• Do not kink or pull the gun around sharp corners
• Keep the gun cable as straight as practical when
welding.
• Do not allow dolly wheels or trucks to run over the
cables.
• Keep the cable clean.
• Innershield electrode has proper surface lubrica-
tion. Use only clean, rust-free electrode.
• Replace contact tip when it becomes worn or the
end is fused or deformed.
