Tungsten contamination is metal or debris transferred to the electrode or weld pool during TIG welding. It can cause unstable arc starts, wandering arcs, inclusions, and visible defects. The usual…
For AC aluminum TIG welding, the best all-around tungsten choice for most modern inverters is 2% lanthanated tungsten. It starts reliably, handles both AC and DC, and does not rely…
Why cup choice matters on stainless A TIG cup does more than direct the arc. Its diameter and shape affect how widely shielding gas covers the weld pool and the…
Field-repairing stainless steel is less about chasing high amperage than controlling heat, protecting the weld from contamination, and having a power source that suits the site. A compact DC TIG…
Aluminum bicycle frame repair is different Aluminum frames are thin, heat-treated structures, not convenient test pieces. A repair can soften the material around the weld, distort a tube, or hide…
MIG wire rusts when moisture and contaminants reach its steel surface. A little surface oxidation can cause more than a rough-looking spool: rust and dirt can clog the liner, increase…
Why vertical-up welds sag On a vertical joint, gravity pulls the molten weld pool down while you work upward. If the pool gets too large or stays liquid too long,…
Small-batch furniture work rewards a MIG welder that starts reliably, runs smoothly at low settings and can handle the material you actually plan to use. For most tables, shelving and…
What Heavy Trailer Frames Demand From a MIG Welder Heavy trailer frames are usually made from 3/16-inch to 1/4-inch steel tubing, channel, angle, or plate. Some axle brackets, coupler mounts,…
What this job demands Joining thin steel sheet to structural tubing is a heat-control problem, not a contest to buy the most powerful welder. The sheet can burn through before…
