The expense regulator universal AR-40/U-30-DM is intended for pressure decline of the gas of argon / carbonic acid coming to the regulator from a cylinder, and maintenance to constants of the set gas consumption at food of electrowelding posts and installations.Technical characteristics Safe! The case and the AR-40/U-30-DM union is manufactured of brass. The sound notification about operation of the safety valve.
The regulator of an expense AR-40/U-30-DM at its use with a carbon dioxide cylinder can freeze because of the reduced gas moisture content at its long selection in large volume. Liquid CO2 carbon dioxide at pressure decline to atmospheric turns into white snegoobrazny weight "artificial ice", temperature - 78,5C (GOST 8050-85). At receipt of CO2 from a cylinder in a reducer without heating there is a freezing of the valve of a reducer, process of pressure decline of gas up to the working pressure and its automatic maintenance stops. To avoid freezing of the regulator of an expense of AR-40/U-30-DM, it is necessary to use a heater of flowing type (taking into account its capacity). For example, a gas heater direct-flow PEU-36 or PU-1 which are connected to the cylinder gate by an entrance with a carving G 3/4'. A heater exit with a carving G 3/4' the regulator of a consumption of AR-40/U-30-DM gas joins. At connection of a heater (PEU-36 or PU-1) to a power line of an alternating or direct current from 36B to 42B (as a rule, the socket for connection is from the back of the case of an automatic welding semiautomatic device or other power supply) the case of a heater heats up to temperature of 85C which is supported by the thermostat automatically. At change of a consumption of gas only time of the included condition of a heater changes. Therefore, we strongly recommend, together with the regulator of an expense AR-40/U-30-DM to get also heaters of gas direct-flow - PEU-36 or PU-1.
The regulator of an expense AR-40/U-30-DM at its use with an argon cylinder can freeze only in that case when the cylinder is filled with the low-quality argon oversaturated by water vapor that argon gaseous and liquid" is violation of requirements of GOST 10157 ".
