Operating Instructions - Klutch MIG 180SG Owner's Manual

vi. Open the Gas Bottle Valve on the cylinder of gas.
vii. Turn the Gas Flow Adjuster on the regulator so that the gas flow rate is set at
NOTE: Slowly open the cylinder valve by turning it counterclockwise until the cylinder
pressure gauge registers on the first gauge of the regulator. Turn the adjustment knob
clockwise (right) slowly to increase gas flow to 20 CFM. To reduce the gas flow, turn the
adjustment counter-clockwise (left). The gas valve is located on the back panel of the welder
and activated by the trigger. Gas flow should be heard when the trigger is activated. No gas
flow will result in a harsh arc with excessive spatter; a smooth weld bead will be difficult to
obtain. Avoid unnecessary gas loss by closing the tank valve when finished welding.
viii. Gas selection
High voltage danger from power source!

Consult a qualified electrician for proper installation of receptacle at the power source. This
welder must be grounded while in use to protect the operator from electrical shock. If you are
not sure if your outlet is properly grounded, have it checked by a qualified electrician. Do not
cut off the grounding prong or alter the plug in any way and do not use any adapter, other than
the supplied adapter, between the welder's power cord and the power source receptacle.
Make sure the POWER switch is OFF then connect your welder's power cord to a properly
grounded 230 VAC (220V - 240V), 60 HZ, single phase, 50 amp power source.
MIG OPERATION
1. POWER SWITCH - The power switch supplies electrical current to the welder. Whenever the
power switch is in the ON position, the welding circuit is activated. ALWAYS turn the power
switch to the OFF position and unplug the welder before performing any maintenance.
2. VOLTAGE CONTROL – Adjust the voltage control to adjust the welding voltage/heat. This unit
has an infinite voltage control. Refer to the Setting Label (inside the wire compartment) for
recommended voltage selector settings for your welding job.
3. WIRE SPEED CONTROL - The wire speed control adjusts the speed at which the wire is fed
out of the welding torch. The wire speed needs to be closely matched (tuned-in) to the rate at
which it is being melted off. Some things that affect wire speed selection are the type and
diameter of the wire being used, the heat setting selected, and the welding position to be
used. Refer to the Setting Label for recommended wire speed settings for your welding job.
any debris in the connection. Connect the regulator to the gas bottle
connection. Use a wrench to snug up the connection.
approximately 20 CFM. Make certain you are reading the correct scale on the
gauge.
Different materials require different shielding gas when MIG welding. Refer to
the set up chart inside the wire feed compartment.

Mild steel: Use 75% Argon and 25% CO2 for reduced spatter and
reduced penetration for thinner materials. Do NOT USE Argon gas
concentrations higher than 75% on steel. The result will be extremely
poor penetration, porosity, and brittleness of weld.

Mild steel: Use CO2 for deeper penetration but increased spatter. (A
CO2 regulator adapter will be needed.)

Stainless steel: Use a mixed gas consisting of Helium, Argon, and CO2.

Aluminum or bronze: Use 100% Argon.
