CONNECTIONS AND POLARITY
REAR (NOTES)
Connections:
To safely connect the regulator to the cylinder, first make sure the cylinder is
properly chained and secured. Then, before connecting the regulator and while standing to the
side of the discharge (not in front of the discharge), briefly crack the valve and allow a 1 to 2 sec-
ond blast of gas to clear any dirt or contamination from the valve seat. Then connect the regulator
and screw the fitting clockwise until finger tight and finish tightening with one (1) 1 1/8” wrench.
Do not use a pair of pliers or other grip/lock devices. Use a large adjustable wrench if no other
wrench is available. Make sure it is tight and slowly open the valve to check the connection for
leaks with luke - warm soapy water (or approved leak detector solution) applied to the fittings at the
valve. To connect the hose to the rear of the unit, screw the 5/8” gas fitting into the gas inlet on the
rear of the unit, rotating clockwise until finger tight. Then use two (2) 3/4” wrenches to complete
the tightening process. One wrench should be placed on the female gas inlet nut and should be
held tightly to while the other wrench is used to finish tightening the male fitting. Do not tighten with
one only one wrench or damage to the female nut and fitting may occur (even though the fitting
seems to be tight and secure enough to hold the pressure). The female side must be held to pre-
vent rotating in the housing and stripping of the fitting inside. Check all fittings and connections for
leaks once again. Do not use thread tape or sealant on threads of the unit, regulator or cylinder.
Plugging and sticking of the gas solenoid valves, regulator or torches may occur if thread sealants
are used. The compression fittings used will tighten up once proper pressure has been achieved.
If the cylinder will not seal, the threads may be worn on the valve or mating surfaces scarred. If
hoses show sign of leaks, tighten the clamps with a pair of side cutters or end nippers. Gently
squeeze the clamp tighter until the leak stops or add an additional clamp only if absolutely neces-
sary. If the regulator leaks, while under warranty contact Everlast for a replacement. Warning !
Never attempt to repair a leaking regulator yourself. The parts are under pressure. Serious
i
njury or death may occur.
Adjustment: The Ball valve will float briefly once the main cylinder valve is opened and will then
settle down and stop floating after 4 to 5 seconds. Fully open the cylinder when in use to prevent
valve leaks. If the valve continues to float, you have a leak. Stop and check. To adjust the gas
flow rate, the welder must be turned on. Select MIG or TIG and set post flow to maximum. Gas
flow is actuated by pressing the trigger on the torch (or pedal) and releasing (or holding depending
upon the mode selected). The small knob on top of the down tube that connects to the hose ad-
justs the gas flow rate. Slowly screw the valve counter - clockwise to increase flow and watch the
ball begin to float. Read the scale where the ball is floating. The ball should float until the gas flow
stops. This meter will work with both Argon and Argon/CO2 mixes. The rate is calibrated in Cubic
Feet Per Hour (CFH). The pressure gauge only confirms pressure inside of the tank. The clear
plastic tube determines actual flow rate. As the cylinder looses pressure near the end, flow rate
may need to be readjusted. This is normal. Read the flow rate of the gas at the middle of the
floating ball. Do not open the cylinder valve quickly or damage can occur to the regulator can oc-
cur over time. Caution! Do not leave the regulator on when not in use or loss of cylinder
contents may occur over time. Asphyxiation may occur if leaked cylinder contents flood
the area as the gas will displace oxygen. Always use the welder with proper ventilation as
well to prevent build up of spent gas.
