The current selector moves a metal knife between contacts attached to various taps of the coil. You can see pictures of the selector in [https://www.mig-welding.co.uk/forum/threads/oxford-bantam-or-rt.21610/#post-237151 this forum post] to give an idea of how to operate it.
The electrode should be connected to the 80 volt terminal for lower current jobs and to the 50 volt terminal when higher current is required. The centre terminal connects to the work lead.

The arc welder is the most basic king of welder, and uses an electrode 'stick' of filler wire. The arc is struck and controlled manually, requiring skill.

Different kinds of filler wire sticks are available with coatings to create a flux suitable for different metal combinations.

Capacity and rating

Users say "very smooth, lots of power".

Power supply

A 32A plug and socket connection is used, with a pushbutton on/off control station and no-volt release. The supply is between phases (415V) allowing a greater welding capacity than previously (when a 13A / 240V supply was used).

Safety

Always make sure that the supply is turned off when you finish using this welder. Do a test strike to make sure.

Selector Switch

The current selector moves a metal knife between contacts attached to various taps of the coil. You can see pictures of the selector in this forum post to give an idea of how to operate it.

The electrode should be connected to the 80 volt terminal for lower current jobs and to the 50 volt terminal when higher current is required. The centre terminal connects to the work lead.
