A wire feed welder is a power tool used for adjoining two metals or thermoplastics. When using this power tool, you need to ensure safety at all time. You must be aware of how your tool works and how to prevent damage to you and your unit. With this particular tool, an expert advises welders to not keep the unit running for more than the allotted time span as this can greatly affect the efficiency of your tool. If using it for long term jobs, you need to let it cool down for a while before using it again. In this way, your machine will be kept in good condition. Follow the step by step guide below to properly operate a wire feed welder.
Step 1 – Set Up the Unit
Coil the machine with spool of E70 welding wire and then fasten the welder’s air gauges to the shielding glass container.
Step 2 – Clamp It to Place
Make sure that your work materials are resolutely held together and are in the right place. Clamp it together so your hands are free to do your task. The space in between your materials must be held firmly in place to get your job done smoothly.
Step 3 – Set the Voltage
Set the voltage according to the need and the type of material you will be using it for. Guide the setting upon the thickness of your material.
Step 4 – Point the Gun
Put on your welding mask, and ensure that the unit’s wire is completely out of the way. Point the welding wire directly to the joint. Remember that the 90-degree angle is used for straight up and down welding procedure and 45 degrees for T-shaped welding procedure. The welding wire should be no more than ½-inch in length from the tip of the gun. You should make sure that the welding wire is at an angle. However, the amount of it varies depending on what type of project you have.
Step 5 – Pull the Trigger
Switch on the unit, and then start tacking the two pieces of materials together as fine welding uses the stringer bead. You just need to weld using the wire in straight line. If you are doing a wider weld procedure, use the weave bead. You just need to draw the wire back and forth in between the adjoining pieces in a curve.
Step 6 – Shut it Down
When you are done with your welding process, you need to make sure that the machine is properly turned off. Have your working materials aside to cool down completely.
