300A / 800A Welding Electrode Holder , Heavy Duty Copper Jaw MMA ARC Welding Rod Clamp

Detailed Product Introduction

This heavy-duty welding electrode holder has two optional specifications: 300A and 800A, matched with MMA ARC welding machines for manual arc welding operations. It is used to firmly clamp welding rods and transmit welding current for metal fabrication, equipment maintenance, construction engineering, auto repair and workshop welding work.

The jaw is forged from pure copper, featuring outstanding electrical conductivity, low resistance and good heat dissipation. It maintains stable current transmission and effectively reduces burn loss during continuous welding. The outer shell and handle are constructed of high-temperature resistant bakelite insulation material. Anti-scald structure protects welders from high-temperature burns.

Adopted ergonomic lever design, it is labor-saving to open and lock welding rods. The grooved non-slip handle provides firm and comfortable grip to prevent slipping during operation. It supports welding rods ranging from 2.0mm to 5.0mm, suitable for welding carbon steel and alloy steel.

300A model is ideal for light and medium welding tasks; the 800A heavy-duty version works for long-hour heavy industrial welding projects. Widely applied in factories, construction sites, automobile repair shops and metal processing workshops.
