One weld SCR is coupled to a first weld terminal and the other weld SCR is coupled to a second weld terminal.

In particular, the device includes a pouch filling station and a sealing station.

The powder is then fed out on a welding area (3).

Said welding stand comprises a welding device (2) and a transport device which is used to transport the spiral tube (1) in relation to the welding device (2).

The welder (100) may also include a switching module (110) in the welding circuit path o: the welder (100) having an electrical switch and a resistive path.

Subsequently, the welding apparatus (1) or the power source (2) are controlled by the control device (4) according to the pre-set welding parameters.

a position at which a welder is working (including equipment)

The welder produces a current between an advancing electrode (E) and a workpiece (W).

The invention also relates to a corresponding welding device used to carry out the process.

A method is also disclosed for automatically clamping tubes in an orbital welder when they are properly aligned.

If you have to do soldering work regularly, then the best option would be to use a soldering station.

The welder (100) includes a short - detecting capability for detecting a short condition upon occurrence of short circuit between the advancing electrode and the workpiece.

An arc welder stator (91) has two groups of slots around a core.

An electric arc welder (100) and a method for performing a pulse welding process producing reduced spatter.

The invention relates to a welding stand (3) which is configured in order to weld a spiral joint (25) of a spiral tube (1).
