Pinnacle IntruARC 141 ARC Welding Machine – 140 Amp Pinnacle Welding Inverter

Pinnacle IntruARC 141 Welding Machine – 140 Amp Heavy Duty Welder Pinnacle Welding – Pinnacle Welding Online This ARC 140 Amp Welding Inverter Machine, IntruARC 141 welding inverter, is manufactured with the latest in advanced IGBT technology. This inverter welding machine includes a digital display for accurate amperage usage. This includes an adjustable ARC-Force to reduce sticking and increase penetration during the welding process. All machines are supplied standard with a 200 Amp welding cable kit. ARC Welding machines known as MMA Welding stands for “Manual Metal Arc” this is an electric process by which an electric arc is struck between the welding electrode and the workpiece. The central metal electrode or core wire provides a filler metal for the weld and the electrode coating provides a shielding pool made up of the weld slag. This Welding process operates with DC or AC power sources, most commonly DC. MMA welding provides a limited amount of weld metal deposited from one electrode and electrodes need to be replaced frequently, making it a less productive process than other methods of welding.
