Product Description

Miller's Dimension 812, CC/CV DC transformer power sources provide outstanding versatility plus the endurance to handle demanding industrial applications. Engineered to provide exceptional performance across a variety of arc welding processes.

Power Source Only

DC Multiprocess capability provides versatility and outstanding arc performance in CV (MIG) and CC (Stick, TIG).

Internal digital voltage control (DVC) enables operator to preset weld voltage in the CV mode prior to welding. 

Built-in Arc Control lets you get in tight without sticking the electrode. An electrode compensation circuit ensures consistent arc control performance regardless of the electrode size. 

Hot Start™ makes it easier to start difficult to start electrodes such as E-6010 and E-7018. 

Line voltage compensation ensures consistent weld performance by keeping power constant even if primary input varies by ±10%.

Fan-On-Demand™ operates only when needed reducing noise, power consumption, and the amount of airborne contaminants pulled through the machine.

Enclosed Circuit Boards provide additional protection form contaminants resulting in longer service life. 

PC board protection prevents the wire feeder power or other stray voltages from harming the power source PC board.

Digital voltmeter and ammeter are easy to read.

Remote voltage control allows operator to change voltage from feeder. 

Thermal overload protection light indicates power shutdown. Helps prevent machine damage if the duty cycle is exceeded or airflow is blocked. 

Simple Control Panel features single range amperage/voltage adjustment. Provides easy and efficient operation.
