As @brightspark said"As long as you can afford", might be the right answer here. But for the home hobby welder what cable length do you guys and gals feel is about right allowing good reach and movement around a garage? Length of electrode and earth please.
Regards
I should have done something to prevent that but I didn't yetI have several 10M lengths of cable from work and they generally snap next to the plugs so they are trimmed back after being taken home and new ends fitted and they go onto a 3 phase stick unit so power and drop is not an issue.
