Most Lincoln welders provide external hookups to install gas welding tanks. The units that do not have this ability are plainly identified on the package when the welder is purchased. The external gas hookup for a Lincoln welder consists of a simple brass fitting with an O-ring gasket. The gas tanks are attached to this brass fitting via a rubber hose and a gas regulator. Ensure that the hose is properly attached to the brass coupler before turning on the regulator.
Locate the brass coupler for gas hookup on the Lincoln welder. It is located either on the backside of the unit or the front.
Insert the gas line fitting into the brass coupler by pushing the brass sleeve toward the welder unit to expose the steel bearings that will hold the gas line in place. Press the gas line into the fitting, then release the sleeve. This will secure the gas line in place.
Switch the welder over to its gas welding setting. Some welders are equipped with this switch, while others are not. If it is equipped with the switch, it is located on the front face of the welder, beside the power dial.
Tips & Warnings
- Use MIG wire for gas welding. Flux core wire may not provide a high-quality weld when used with additional shielding gas.
