OPERATION
WELDING PROCESS
Your Eastwood MIG135 can be used to form a large number of different joints and welds all of which will require practice
and testing before using on an actual project piece. This following welding process is just a baseline to get you started.
1.
Refer to the ‘Suggested Settings’ chart which is located inside the side door of your Eastwood MIG135 as well as below in the
instruction manual. From the chart select your baseline starting point for the recommended settings described in the chart.
2.
Change the output polarity if necessary according to the welding wire’s specifi cations. This welder comes set up
to use Solid MIG wire, if using Flux Cored wire, the polarity will need to be changed.
3.
Connect your ground clamp to the work pieces that are to be welded. Make sure the ground clamp contacts are placed
on a clean piece of metal free of paint, grease, rust, oils, etc. It is recommended to place your ground clamp as close
to the weld area as possible.
4.
Assess your weld area and make sure the welding area is also cleaned of any paint, grease, rust, oils, etc.
5.
Plug in the welder and switch to the ON position.
6.
Open your gas valve on the bottle and adjust the fl ow rate if necessary.
7.
Depress the MIG Gun trigger pointing the welding gun away from your body and then let go of the trigger and
cut the wire back to ~1/4” stick out length.
8.
Wearing your welding helmet, gloves, and long sleeve shirt and pants, put the end of the wire sticking out of
the gun into the joint to be welded.
9.
Position the MIG Gun so that it is perpendicular to the base metal with ~20° tilt back.
10.
Depress the trigger to start the wire feed which starts the arc.
NOTE:
A push, perpendicular, or drag technique can be
used to weld the pieces together; the type used depends on the type of joint as well as other infl uential conditions.
11.
Once you depress the trigger and the arc has started, you will notice a molten puddle will form; this puddle is the weld bead
and will follow the motion of the MIG Gun. Watching the size of the puddle dictates how fast you should be moving with the torch.
If you burn through the material you are either moving to slow or you need to make some setting adjustments to the welder settings.
If you’re not penetrating the base metal you’re either moving too fast or you need to make adjustments to the welder settings.
12.
Release the trigger on the MIG Gun to stop the weld.
13.
After fi nished welding, close the valve completely on the Shielding Gas Bottle.
FOR EASTWOOD MIG135 WELDERS WITH
SET SCREW STYLE DRIVE ROLLER
1.
Turn off the welder and unplug the welder from power.
2.
Unlock the Pressure Adjuster (Fig. H1) by pulling the top wing
nut towards the rear of the welder.
3.
Lift the Rocker Arm (Fig. H2) and rotate the drive roller by hand
until you have access to the set screw in the center of the roller.
4.
Loosen the set screw.
5.
Slide the drive roller off the shaft.
6.
Determine which size wire is going to be used and slide the
Drive Roller back onto the shaft by lining up the set screw with
the fl at area on the shaft.
NOTE:
The stamped marking on the
side of the Drive Roller indicates the size of the groove on the opposite side of the roller. The groove closest to the drive motor is the
groove that will be used. If setting up to use 0.035” (0.6mm) wire, the ‘0.6’ stamping should be facing the user when installing it.
7.
Tighten the set screw on the Drive Roller and lower the Rocker Arm (Fig. H2) back into place.
8.
Lift up on the Pressure Adjuster (Fig. H) to put back in place and adjust as necessary.
