WARNING

Gas under pressure is explosive. Always keep gas cylinders in an

upright position and always keep

chained to undercarriage or sta-

tionary Y support. See American National Standard Z-49.1, “Safety in Welding and Cutting” published

by the American Welding Society.

____________________________________

1.Set the gas cylinder on the rear platform of the WIRE-MATIC 250.

2.Hook the chain in place to secure cylinder to rear of welder.

3.Remove the cylinder cap.

4.Inspect the cylinder valves for damaged threads, dirt, dust, oil or grease.

a. Remove dust and dirt with a clean cloth.

NOTE: DO NOT ATTACH THE REGULATOR IF OIL, GREASE OR DAMAGE IS PRESENT! Inform your gas supplier of this condition. Oil or grease in the pres- ence of high pressure oxygen is explosive.
