Gas Installation - Klutch MIG250S Owner's Manual

4.2.15 Plug in the welder power cord and turn the welder ON. Set the Voltage switch to the
voltage setting recommended for the gauge metal that is to be welded. Refer to the set-up chart on
the back side of the drive compartment door.
-The welding wire is electrically hot when the power is on and the torch trigger is activated.
4.2.16 Set the WIRE SPEED control to the middle of the wire speed range.
4.2.17 Straighten the MIG torch cable and pull the trigger in the gun handle to feed the wire
through the torch assembly. When at least one inch of the wire sticks out past the end of the torch,
release the trigger.
4.2.18 Turn the Power Switch to the OFF position.
4.2.19 Select a contact tip stamped with the same diameter as the wire being used.
NOTE:
- Due to inherent variances in flux cored welding wire, it may be necessary to use a contact tip one
size larger than your flux core wire if wire jams occur.
4.2.20 Slide the contact tip over the wire (protruding from the end of the torch). Thread the contact
tip into the end of the torch and hand-tighten securely.
4.2.21 Install the nozzle on the torch assembly.
4.2.22 Cut off excess wire that extends past the end of the nozzle more than 1/4 inch.
4.2.23 Turn the welder ON.
5. SETTING THE DRIVE ROLL TENSION

Arc flash can injure eyes! To reduce the risk of arc flash, make certain that the wire
coming out of the end of the torch does not come in contact with the work piece, ground
clamp, or any grounded material during the drive tension setting process or arcing will
occur.
5.1 Press the trigger on the torch.
5.2 Turn the drive tension adjustment knob clockwise until the wire seems to feed smoothly without
slipping.

6. GAS INSTALLATION

Shielding gas cylinders and high pressure cylinders can explode if damaged, so treat them
carefully.

Never expose cylinders to high heat, sparks, open flames, mechanical shocks or arcs.

Do not weld on the cylinder.

Always secure cylinder upright to a cart or stationary object.

Keep cylinders away from welding or electrical circuits.

Use the proper regulators, gas hose and fittings for the specific application.
