Welding machines are complex and even if a small thing goes wrong it will have a huge effect on the machine and your welding work.
If your welding machine won’t start it might be because of a blown power supply line fuse, dead power circuit, overloading or wrong voltage input.
This can either be because the fuse is too small or because there is a short circuit in the connections.
If your welding machine suddenly stops during welding it might be due to overloading, an obstruction in ventilation or the dysfunction of the internal cooling fan.
This problem could be because of a worn-out connection or due to improper use of the switch when the welder is still under load.
This is a common problem and could be due to a loose connection or inappropriate duty cycle of the electrode holder.
You may occasionally receive small electrical shocks while touching the welder. It might not happen all the time but can be dangerous. This usually occurs if the frame of your welding machine isn’t grounded properly.
Sometimes the welding cable will get hot very fast. When this happens, the cable used in the welding machine is likely not of proper size with an inappropriate duty cycle.
If the ground clamp of the welding machine gets coated with oxides the electrons can’t transfer easily. This creates high resistance on the machine and alters the flow of the current.
The cable will get damaged over time, resulting in frayed and worn areas. Chat to Tru-Butt about replacing the cable safely.
If your welding machine doesn’t switch off until the power supply is turned off, the line switch is worn out or has failed mechanically. Tru-Butt can fix that for you.
In addition to problems with your welding machine, you might also battle with welding defects.
The reason for improper wire feeding might be a worn-out drive roller. This could also cause the wire feed to slip.
If the tip inside the welding gun is worn, the power from the welding machine doesn’t adequately hit. This creates extra work for the welder.
This commonly occurs on the surface of the bead as the result of bad wiring or inadequate gas flow.
If the wire is rusty or dirty, or if the bead is too small and concave there might be shrinkage cracks on the weld.
If you weld too fast or battle with a very low current and high voltage arc, you can expect some lateral cracks.
A lot of spatter could be the result of too much high voltage or excess CO2.
Maintaining your welding machine is essential to avoid problems and minimise defects.
