Lincoln Electric Arc Welder SAE 400

● Do not touch electrically live parts such as output terminals or internal wiring

● Use in open, well ventilated areas or vent exhaust outside

● Do not operate with doors open or guards off

Warning: This procedure requires trained personnel with PPE!

This welder is equipped with a double-shielded ball bearing having sufficient grease to last indefinitely under normal service.

Is the welder used constantly or in excessively dirty locations?

If yes, it may be necessary to add one-half ounce of grease per year.

A pad of grease one inch wide, one inch long and one inch high weighs approximately one-half ounce.

Over greasing is far worse than insufficient greasing.

When greasing the bearings, keep all dirt out of the area.

Wipe the fittings completely clean and use clean equipment.

More bearing failures are caused by dirt introduced during greasing than from insufficient grease.
