I WISH A FEW MORE FOR ALL MY WELDING MACHINES AND PLASMA CUTTER THIS PLASMA CUTTER COMES WITH COPPER MAGNET WIRE Magnet to clamp the ground wire onto the wire of the welding machine and the plasma cutter, it certainly provides excellent ground contact for arc welding, wire welding, TIG welding and plasma cutting. No more ground clamp for my welders except when welding alum with a spool gun or TIG welding. What I love most about this product is the extra spring and the contact witch is amazing. I recommend this magnet for welding grounding. noti welds and installs tubular fences, entrances and gates among other projects around the farm and home. I wish I had known that many years ago
