2.3.7 Gas cylinder installation
The welder has a platform on the rear of the unit to support a gas cylinder (see fig. 2-7). If you plan
to move the welder around the shop, use only small cylinders for transport safety (outside diameter = 140
mm, height ≤ 500 mm, weight ≤ 10 Kg, service pressure ≤ 20 Mpa). Larger cylinders (outside diameter >
140 mm, or height > 500 mm, or weight > 10 Kg, service pressure ≤ 20 Mpa) should be secured in a
permanent location or to a separate cart, not to the welder. Secure the small cylinder with the straps
supplied with the welder. Small cylinders can be easily secured in place using the top rack "A".

2.3.8 Connecting welder to a gas cylinder.
Clean the threads of the gas cylinder valve. Open the gas valve for a few seconds to blow out any
dirt or particles that may have entered the orifice, in order to prevent them from entering the regulator.
Check the regulator (outlet flow meter: 0-25L/Min., inlet gauge: 0-25 Mpa, pressure range for safe
outflow: 0-0.35 Mpa) to make sure that it was supplied with a gasket. Tighten the regulator coupling
to the cylinder gas valve. Now connect the welder gas line to the hose barb outlet on your regulator.
A stainless steel hose clamp can be used to ensure a leak-proof connection (see fig. 2-8).
Check all connections for leaks by opening the regulator and cylinder gas valves.
Always shut off the regulator and cylinder gas valves when the unit is not in use.
