Practical answers on choosing, fitting and looking after replacement parts for a compact stick welding machine.
Start with the rating plate on the machine. It identifies the maker, the type and the electrical ratings, and if the handbook has gone missing it is often the only specification you have. Note the type and serial details exactly as printed.Then use the parts list in the manual, which matches each part to the machine type. A part that looks the same can differ in fit or rating between versions of a range, so do not rely on appearance alone. Photograph the old part and its position before removing it, and read any markings on it. If the type or version is unclear, ask a welding-equipment supplier or the maker's service agent to confirm before you buy.
Only if you are competent to do electrical work. The law expects anyone doing work where technical knowledge is needed to prevent danger to have that knowledge or to be properly supervised, and a welder's mains cable carries the full input current. Makers generally say a mains cable should be replaced by a qualified electrician or an authorised service agent.When buying a replacement, match the cable to the data plate and manual: cable type, conductor size, plug and fuse must suit the machine's input rating. Never swap in a lighter household lead, and never keep using a damaged cable. After the work, the machine should be inspected and tested before it goes back into use.
Look before each use, with the machine unplugged. Signs include cuts, crushing or scorching on the sheath, the cable pulled out of its clamp, exposed conductors, a cracked or loose plug body, bent or discoloured pins, and a plug that feels warm in use.A brief user check is a recognised part of looking after portable electrical equipment, and most electrical defects can be found simply by looking. Do not mend a damaged cable with tape. If you find damage, stop using the machine, unplug it and have the cable replaced by a competent person. Machines that are dragged or carried by the lead tend to suffer sooner, so keep strain off the point where the cable enters the casing.
Start with a visual check: covers fitted, cable clamped, no loose screws or stray wire. Some faults, such as a poor earth connection or weak insulation, cannot be seen, so after repairs involving electrical parts the machine should be inspected and tested by a competent person using suitable test equipment. A standard exists for inspection and testing of welding power sources after repair.Keep a note of what was changed and when. Then make a trial weld on scrap at a modest setting, watching for unusual smells, noise, heat at the sockets or an unstable arc. Stop and unplug the machine if anything seems wrong.
