AK-2 or AK-3?
Choose AK-2 for .040, 1/16 and 3/32 in consumables, #4/#5/#6 cups and a short backcap. The AK-3 kit covers 1/16, 3/32 and 1/8 in sizes and includes both short and long backcaps.
Check whether the torch uses standard 3-Series components or has a stubby or gas-lens conversion. These kit parts are not automatically interchangeable with every converted front end. The kit does not include a complete torch.
Confirm the welding procedure, cup size and electrode preparation for the job. For additional electrodes, see the 1/16 in and 3/32 in ceriated packs.
