WELDING PROCESS
Your Eastwood MIG175 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 MIG175 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 specifications. 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 flow rate if necessary.
7.
Depress the torch 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 welding 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
influential 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 welding torch. 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 welding gun to stop the weld.
13.
After finished welding, close the valve completely on the Shielding Gas Bottle.
OVERLOAD PROTECTION
Your Eastwood MIG175 is equipped with a temperature controller as well as an overload breaker. These two protection devices will protect your welder if the duty
cycle is exceeded. If the output is exceeded, the internal breaker will trip and stop power supply to the drive motor although the fan will still run to cool the unit.
If the breaker tripped resulting from an overload, the circuit breaker button on the rear of the welder will extend out. This circuit breaker must be reset manually.
Before resetting the circuit breaker button allow the welder to cool for a minimum of 15 minutes.
If there is no voltage output and the circuit breaker was not tripped, the internal thermal protector may have shut off the welder until it cools to normal operating
temperature. This is an automatic function and does not require the user to manually reset anything.
