5. SETTING THE DRIVE ROLL TENSION
⚠WARNING
• 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.
a. Press the trigger on the torch.
b. Turn the drive tension adjustment knob (Figure 2) clockwise until the wire seems to
feed smoothly without slipping.
6. GAS INSTALLATION
⚠WARNING
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 the cylinder upright to a cart or stationary object.
• Keep cylinders away from welding or electrical circuits.
• Use the proper regulators, gas hoses, and fittings for the specific application.
a. Polarity Changing - When MIG wire is used, shielding gas is required and the polarity
on this unit needs to be electrode positive.
i. Electrode Positive for MIG Welding - The Weld Power Cable should be
connected to the Positive (+) weld output connection on the front of the
machine. The ground cable would then be connected to the Negative (-) weld
output connection. Refer to the polarity setting label inside the wire
compartment.
ii. Electrode Negative for Flux Core Welding - The Weld Power Cable should be
connected to the Negative (-) weld output connection on the front of the
machine. The ground cable would then be connected to the Positive (+) weld
output connection. Refer to the polarity setting label inside the wire
compartment.
iii. Connect one end of the gas hose to the gas hose connection on the back of
the welder. Use a wrench to snug up the connection.
1. This welder has two gas valves on the back of the machine. Locate
the gas valves and identify which gas valve is for the MIG gun and
which gas valve is for the spool gun.
