Aluminum motorcycle parts are among the least forgiving jobs for a TIG welder. Engine covers, brackets, subframes, rearsets, and fabricated fuel or oil tanks often use thin aluminum that overheats…
Stainless-steel benches look simple, but long, visible seams make them unforgiving to weld. A TIG machine gives you precise control over thin sheet and clean corners, provided it has a…
What matters when TIG welding thin-wall aluminum tubing Thin aluminum tubing is easy to distort and easy to melt through. A welder that can produce a stable arc at low…
Why TIG for copper heat exchanger repairs Copper conducts heat quickly, so a small repair can pull warmth away from the weld before the joint fuses. That makes TIG useful:…
Stainless food-service frames demand cleaner work than ordinary shop fabrication. The welds may be exposed, wiped down repeatedly, and inspected for pinholes, undercut, trapped contamination, or rough crevices. A good…
MIG spatter around a contact tip can usually be removed with a hand reamer and a wire brush. The nozzle itself needs more care: gouging its bore, bending the tip,…
Skip welding is a way to join steel in short, separated welds instead of running one continuous bead along the joint. The unwelded sections are filled later, after the first…
MIG gas preflow and postflow control how long shielding gas runs before and after the arc. Set them too short and air can contaminate the weld at startup or as…
When vertical-down MIG works Vertical-down welding moves the torch from the top of a joint toward the bottom. On thin sheet, that direction can help limit heat buildup and reduce…
Short MIG welds are deceptively easy to ruin. A 2-inch seam can pull a panel out of alignment just as quickly as a long weld, especially on sheet metal, tubing,…
