Magnetic work clamp and arc blow

admin

I'm sure I'm revealing my ignorance of the finer points of magnetic arc blow, I can't even be sure I've experienced it.With stick in DC I've had weird behaviour our of the puddle where the filler seems to shoot out or to the side of the puddle, and solved it with repositioning the feng shui of my clamp and leads... That was with a regular clampSince I got my mig machine, I've never really experience the same phenomena or anything.  I'm thinking of making a magnetic work clamp for situations where there isn't a good spot for the alligator style clamp.Just wondering about arc blow and if I'm asking to go down that road. I've seen a stick weldor that I know using a magnetic clamp but I can't be sure he wasn't in AC (where I understand arc blow isn't an issue).

Reply:harbor freight has a cheap magnetic ground puck--you can hook your alligator clamp to the stud on it and try it.
Reply:i have a magnetic ground clamp with an on/off switch, got it from my LWS, havent had any problems with it yet, but it works best on nice new metal-NateMiller Trailblazer 302gMiller Spoolmatic 30aLN-25 x 2Idealarc SP200Hypertherm Powermax 600
Reply:The magnetic field that is affecting the arc is very localized around the magnet.  The strength of the magnetic field is approximately one quarter as strong when you move twice the distance away from the magnetic source.  It is unlikely that you will be welding within inches of the location of your magnetic ground clamp.
