Magnetic Weld Ground 300 A
The Mag-Mate WG300R is a magnetic welding ground rated for 300 A maximum current. It uses a rare-earth magnet to attach securely to flat or pipe surfaces. The clamp body is steel and includes a 1/2-13 x 1-1/4 in. ground bolt for cable connection.
Suits welders needing quick setup on ferrous
This ground clamps on and releases with an on/off switch, removing the need for mechanical jaws on clean steel. It accepts cable up to 4 AWG via bolt and nut termination. Welders working primarily on non-magnetic alloys or requiring a jaw-style clamp for painted or rusted surfaces should consider other grounding methods.
Fits tight joints with five preset angles
The compact body measures 2.9 in long, 1.9 in wide and 2.8 in high, allowing placement in confined areas. Five positioning angles — 45, 75, 90, 105 and 135 degrees — let the cable approach from multiple directions. The 150 lb magnetic pull holds the ground firm during welding, freeing both hands for torch control.

Questions about this item
What cable gauge must my welding lead already be for the bolt and nut connection?
The clamp accepts a maximum of 4 AWG cable secured with the included 1/2-13 x 1-1/4 in. grade bolt and nut.
Will the 150 lb pull hold on the 45 and 135 degree positioning angles I use for pipe work?
Yes, the rare-earth magnet is rated for 150 lb maximum pull at all listed angles: 45, 75, 90, 105 and 135 degrees.
How do I confirm the ground is making proper contact after I mount it?
Check that the on/off lever is fully engaged, the magnet sits flush on clean flat or curved steel, and the cable bolt is tight.
