How do I set up the Miller 350P welder for the first time?

Start by installing the work clamp to the negative output terminal, then install the welding gun through the opening until it bottoms against the drive assembly and secure with the gun securing knob. Connect the gun trigger plug and tighten the threaded collar. Install the gas supply by connecting the regulator/flowmeter to the rear panel with a typical flow rate of 20 cfh. Finally, thread the welding wire through the wire guides and drive rolls, adjusting hub tension so a slight force is needed to turn the spool. (Pages 10-19)
