what causes saturation in welding machine
in welding machine, the transformer used is basically a current transforrmer. so by changing the tap of secondary side of transformer, we can increase or decrease the current in the transformer.
A welding transformer is an electrical transformer used in welding power supply. It pulls relatively low current drawn from the mains power (typically limited to 15 A to avoid tripping the circuit breaker) and converts it to the typical 50 A to 500 A used in arc welding and higher currents used in spot welding. The main difference between a Normal Step Down Transformer & a Welding transformer , is Not only to Step Down ( lower ) the outlet supply voltage and at the same time increase the Available Output Circuit Current, but to be also able withstand the Short Circuit Conditions on the Welding Output Side and especially for the Magnetic ( Iron Lamination Core ) Part of the Transformer. This Magnetic Path difference prevents the Supply side Electrical Circuit from Oveloading , espcially during the Striking of the Arc, when the Welding Electrode & the Welding Job touch to initiate an Arc, after which the Welding Electrode is lifted slightly by Experience, to maintain the required weld flow. A Normal Transformer of equivalent rating will not be able witstand this operation without burning out.

which oil use for arc welding machine
When the curent Is in the secundary for the highervalues Ip in the primary coil are not equal proportional than for the lower curent. Is/Ip for lower values is for exemple 100 Is/Ip for higher values are for exemple 70The reason is the magnetique flux saturation in the closed iron core.Roger
A welding transformer uses the alternating current supplied to the welding shop at a high voltage to produce the low voltage welding power

SMAW stands for shielded metal arc welding. The rectifier used in the welding machines must be referring to this type welding.
two reasons i can think of: 1 - Probably dont need to, usually welding material of constant thickness. 2 - The transformer is mechanically adjusted on most welders, this means that that there would be a possibility for electricity jumping in the transformer, and premature failure, or fire.

With the possible exception of a variable reluctance transformer, you should always avoid core saturation of any type of transformer. When saturated the magnetic characteristics of the core material is radically changed and the coupling coefficients will be very different. Additionally, many transformers can overheat and be damaged.
