DON’T BUY ELECTRODE HOLDERS WITHOUT THIS MARKING.
Choose your holder according to the maximal electrode diameter you use. This diameter dictates the maximum amperage and subsequently the size of the welding cable. Once the above criteria are established, the remaining choice is one of personal preference.
Screw type: Very secure grip of the electrode that gives the possibility to twist the electrode once tightened.
Lever type: Secure grip of the electrode between the jaws with predefined angles for the electrode position, easy butt ejection.
