just picked me up a mag-mate WG200R welding clamp . the unit is rated at 200 amps and she has some clamping power of 150lbs . only 2 bad things i see off the top are the ny-lock nut might melt from heat but thay say this unit is NOT to be in the area of over 180*f temps . and the bolt is HUGE dia and length . otherwise this thing is quality in fell and quality of work put in to it . this should make welding a lot better as we all know sometimes finding a way to clamp the ground is hard to do . i got to thinking this would prob work great for the plasma cutter also . . .
